[PATCH] fix broken cross compiles
The change to kbuild to use -isystem `gcc -print-file-name=include`
broke our parisc crosscompile (and presumably everyone else's).
The reason is that you have a := in the NOSTDINC_FLAGS rule, which is
evaluated in situ (i.e. before we've had a chance to set CROSSCOMPILE
on CC) so the gcc include path is actually the native one not the
crosscompiler one. On parisc this causes us to be unable to handle
_builtin_va functions, but I bet there are a heap of other problems.

[PATCH] ppc64: fix use kref for device_node refcounting (fix)
The recent ppc64 patch to use kref for device_node refcounting
introduced an unbalanced get/put in of_add_node which would cause
newly-added device nodes to be prematurely freed. Sorry for the
screwup, a more rigorously tested fix follows.

[PATCH] Include type information as module info where possible
Module parameters no longer have a type in general, as we use a callback
system (module_param_call()). However, it's useful to include type
information in the commonly-used wrappers: module_param,
module_param_string and module_param_array.

[PATCH] matroxfb: FB_MATROX_G Kconfig changes
The current Kconfig entries for the Matrox G cards are quite confusing:
config FB_MATROX_G450
bool "G100/G200/G400/G450/G550 support"
depends on FB_MATROX
config FB_MATROX_G100A
bool "G100/G200/G400 support"
depends on FB_MATROX && !FB_MATROX_G450
The patch below contains:
- remove FB_MATROX_G100{,A} and rename FB_MATROX_G to FB_MATROX_G450
(FB_MATROX_G450 included support from the G100 to the G550, so
I don't see any non-historic reason why to call it G450)
- small update for the FB_MATROX_G Kconfig text
The disadvantage of this patch is, that you can no longer select support
only for the G100-G400 without supporting the G450 and G550. But
compared with the current confusing Kconfig setup, I don't think that's
a big issue.

[PATCH] intelfb: Workaround for 830M
This is a work around for the 830M with intelfb. Relative to 2.6.10. Without
this patch, updates to the DSPACNTR register will be ignored.
On the 830M, the display plane needs to be enabled before writing to any of
the other bits in the DSPACNTR register.
This patch detects the specific case, temporarily enables the plane, updates
the register, and then disables the plane. It also appears to require some
settling time, but not an entire frame's time.
Without this change, the pixel format fields in DSPACNTR won't get written on
the 830M.

[PATCH] vesafb: Change return error id
With <Stuart_Hayes@Dell.com>
I'm getting a message in dmesg: "localhost kernel: vesafb: probe of vesafb0
failed with error -6"
I searched the web, and found that a lot of people are getting this, but I
couldn't find an answer, so I looked into it.
This appears to be because "vesafb" returns -ENXIO ("No such device or
address") when its probe function fails. However, driverse/base/bus.c spews
an error message during device_attach() if a matching driver's probe function
returns anything but -ENODEV ("No such device").

[PATCH] InfiniBand/mthca: clean up ioremap()/request_region() usage
From: "Michael S. Tsirkin" <mst@mellanox.co.il>
Here are misc fixes for mthca mapping:
1. Thinkably, MSI tables or another region could fall between HCR
and ECR tables.
Thus its arguably wrong to map both tables in one region.
So, do it separately.
I think its also more readable to have ecr_base and access ecr there,
not access ecr with hcr pointer.
2. mthca_request_regions error handling was borken
(wrong order of cleanups). For example on all errors
pci_release_region was called which is wrong if the region
was not yet mapped. And other such cleanups.
3. Fixed some error messages too.

[PATCH] ext2/ext3 ACLs: remove the number of acl entries limit
This patch removes the arbitrary limit of 32 acl entries on ext[23] when
writing acls. A patch that removes the same check when reding acls is in
BK since 12 March 2004, so all kernels since then are already able to read
large acls. I think that ten+ months are enough so that we can now also
remove the write limit.
This is the read-limit patch:
http://linux.bkbits.net:8080/linux-2.6/cset%404051e2863UsuQEgAQShmimgBooAXkg?nav=index.html
Even without this patch the xattr block could already contain less space
than needed for the acl, because other attributes might already use up
almost all space. So this patch does not introduce additional error
conditions. We have been shipping with this patch the last year (almost).

[PATCH] ext3: fix ea-in-inode default ACL creation
When a new inode is created, ext3_new_inode sets the EXT3_STATE_NEW flag,
which tells ext3_do_update_inode to zero out the inode before filling in
the inode's data. When a file is created in a directory with a default
acl, the new inode inherits the directory's default acl; this generates
attributes. The attributes are created before ext3_do_update_inode is
called to write out the inode. In case of in-inode attributes, the new
inode's attributes are written, and then zeroed out again by
ext3_do_update_inode. Bad thing.
Fix this by recognizing the EXT3_STATE_NEW case in ext3_xattr_set_handle,
and zeroing out the inode there already when necessary.

[PATCH] ext3/ea: disallow in-inode attributes for reserved inodes
When creating a filesystem with inodes bigger than 128 bytes, mke2fs fails
to clear out bytes beyond EXT3_GOOD_OLD_INODE_SIZE in all inodes it creates
(the journal, the filesystem root, and lost+found). We would require a
zeroed-out i_extra_isize field but we don't get it, so disallow in-inode
attributes for those inodes.

[PATCH] ext3/ea: ix i_extra_isize check
We are checking for (EXT3_SB(inode->i_sb)->s_inode_size <=
EXT3_GOOD_OLD_INODE_SIZE) to find out if we can set in-inode attributes;
the test fails for inodes that have been created before the ea-in-inode
patch. Those inodes have (i_extra_isize == 0), so we end up with the
attributes overlapping the i_extra_isize field. Checking for
(i_extra_isize == 0) instead fixes this case.
The EXT3_STATE_XATTR flag is only set if (i_extra_isize > 0) and the inodes
has in-inode attributes, so that is enough in the first two tests.

[PATCH] ext2/ext3: block allocator startup fix
We found strange blocks layout in our mail server, after careful study, we
got the reason and tried to fix it.
On the very fist attempt to allocate a block to the newly-initialised inode,
if we are trying to add a block at logical file offset "1" then
ext2_find_goal() will incorrectly assume that this was a next_alloc_block
cache hit (because we think the previously-allocated block was at offset
zero).
Net result: why trying to extend a freshly-opened one-block file we end up
deciding to place the second file block at disk block "1", rather than going
off and calling ext2_find_near().
Fix it by checking that we actually do have something valid cached in
next_alloc_goal.

[PATCH] x86: no interrupts from secondary CPUs until officially online
Andi Kleen reported a problem where a very slow boot caused the timer
interrupt on a secondary CPU to go off before the CPU was actually brought
up by the core code, so the CPU_PREPARE notifier hadn't been called, so the
per-cpu timer code wasn't set up.
This was caused by enabling interrupts around calibrate_delay() on
secondary CPUs, which is not actually neccessary (interrupts on CPU 0
increments jiffies, which is all that is required). So delay enabling
interrupts until the actual __cpu_up() call for that CPU.

[PATCH] ppc64: use kref for device_node refcounting
This patch is from Nathan Lynch <nathanl@austin.ibm.com>.
This changes struct device_node and associated code to use the kref api for
object refcounting and freeing. I've given it some testing on pSeries with
cpu add/remove and verified that the release function works. The change is
somewhat cosmetic but it does make the code easier to understand... at least
I think so =)
The only real change is that the refcount on all device_nodes is initialized
at 1, and the device node is freed when the refcount reaches 0 (of_remove_node
has the extra "put" to ensure that this happens). This lets us get rid of the
OF_STALE flag and macros in prom.h.

[PATCH] ppc64: clear MSR_RI earlier in syscall exit path
This patch is from Craig Chaney <cchaney@us.ibm.com>.
This patch moves the restoring of the stack pointer in the system call exit
path to after the point where we clear the RI (recoverable interrupt) bit in
the MSR. Normally, loading the stack pointer before clearing RI doesn't cause
any problem because there is no trap that can normally occur in between. But
if we are tracing the code using a tool that single-steps instructions, this
can cause a problem. In this case, clearing RI serves as an indication that
the following code can't be safely single-stepped.

[PATCH] mm: adjust dirty threshold for lowmem-only mappings
With Rik van Riel <riel@redhat.com>
Simply running "dd if=/dev/zero of=/dev/hd<one you can miss>" can cause
excessive amounts of dirty lowmem pagecache, due to the blockdev's
non-highmem page allocation strategy.
This patch effectively lowers the dirty limit for mappings which cannot be
cached in highmem, counting the dirty limit as a percentage of lowmem
instead. This should prevent heavy block device writers from pushing the
VM over the edge and triggering OOM kills.

[PATCH] removing bcopy... because it's half broken
Nothing in the kernel is using bcopy right know, and that is a good thing.
Why? Because a lot of the architectures implement a broken bcopy()....
the userspace standard bcopy() is basically a memmove() with a weird
parameter order, however a bunch of architectures implement a memcpy() not a
memmove().
Instead of fixing this inconsistency, I decided to remove it entirely,
explicit memcpy() and memmove() are prefered anyway (welcome to the 1990's)
and nothing in the kernel is using these functions, so this saves code size
as well for everyone.

From Terence Ripperda <tripperda@nvidia.com>

Since the last round of change_page_attr changes this would

The problem would be only visible on machines with >3GB of memory,
because only then the PCI memory hole is below end_pfn and
change_page_attr is used.
Fixed for both i386 and x86-64.
This was actually discovered&fixed by Andrea earlier, but I goofed up

[ARM PATCH] 2431/1: Split arch specifics out of arch/arm/kernel/debug.S
Patch from Ben Dooks
This patch moves all the machine/arch specific bits out of

are placed into include/asm-arm/arch-*/debug-macro.S.
The aim is to clean-up the debug.S code and make it easier to
modify a single-architecture without affecting the entire
debug.S file.
The patch also removes CONFIG_ARCH_FTVPCI, which no longer
exists anywhere else in the kernel.
All new include files have the original copyright notice
from arch/arm/kernel/debug.S.
Note, not all architectures modified here have been built

[IA64] remove superfluous layer from sn2 DMA API
When I converted the sn2 code over to the new DMA API, I left the old routines
in place and added wrappers to call them from the generic DMA API functions.
This added an unnecessary level of obfuscation since the generic ia64 code
calls those functions when any of the old style PCI DMA API functions are
called. This patch rectifies the problem making the code much easier to
understand and hopefully a little more efficient (though I'm sure gcc was
already inlining things pretty well, there were a bunch of unnecessary checks
that I took this opportunity to remove). It also shrinks the size of the sn2
pci_dma.c quite a bit.

[IA64] new api efi_range_is_wc()
Ok, here you go Tony. This one fixes the loop and also fixes drm_vm.c. All

This patch adds efi_range_is_wc() to efi.h. It's used to determine whether an
address range can be mapped with the write coalescing attribute. It also
fixes up some ia64 specific callers to use the new routine instead of
unconditionally calling pgprot_writecombined, which can be dangerous if used
on ranges that don't support it.

psr.pp/dcr.pp, via IPI. This is when the stop is triggered
by a close(), either explicit in the application or implicit
via exit_files(). The IPI is necessary because at the time the
thread (controlling the context) issues a close() it may not run
on the CPU the context is bound to. Yet the call must succeed,
hence we need to propagate the call to the right CPU.
But what is the problem then?
Under IPI, we invoke a perfmon routine which clear the kernel
(live) kernel psr.pp bit and also dcr.pp. Then we return from
the function and execute the kernel exit path which restores
the interrupted state. Unfortunately, this restores the kernel
psr from ipsr which now contains a stale value. Therefore
monitoring in the kernel will be active even though we stopped it.
You cannot modify the "global" psr in an interrupt routine because
it will be systematically restored on the way back.
Solution:
We need to patch ipsr.pp in the kernel exit path to reflect the
kernel value of the kernel psr.pp bit. This must be done only when
returning to kernel.
The proposed patch does patch ipsr.pp such that it is identical
to psr.pp. The patch is subtle because the exit path does not have
a lot of free registers and also because we need to schedule for
a psr read. I had to shuffle things around a little bit.
The patch is important because there will be another situation where
this problem can occur once we incorporate the support for event set
and multiplexing. In this configuration, you may be in the middle of
the idle loop and on a timer interrupt, you may stop monitoring.
Slightly different condition, yet same problem with ipsr.pp vs. psr.pp.
Changelog:
- update kernel exit path when returning to kernel to copy
psr.pp to ipsr.pp. This is necesary to ensure that if psr.pp
was modified during the kernel entry, the change is propagated
the the psr.pp of the of the interrupted thread. Psr.pp can
be modified as a consequence of an IPI under certain conditions,
such as when a system-wide context is closed from a remote CPU.
Special thanks to David for reworking the patch to fit
into the enhanced exit path.

When compiling for non-NUMA variable "node" ended up not being used,
which solicits a warning from GCC. Fix is to evluate cpu_to_node(i)
in place. This has the effect of doing cpu_to_node(i) twice on NUMA,
but this is init code, so performance is not an issue (and even if
it were, you can just declare cpu_to_node() as being a pure function,
so the compiler can eliminate the second call).

[PATCH] PPC64: fix stack alignment for signal handlers
The PPC64 ABI specifies that the stack should be kept aligned to 16
bytes. However, signal handlers on PPC64 are getting run with the stack
misaligned (sp % 16 == 8). This patch fixes that by ensuring that the
signal frame allocated is a multiple of 16 bytes.
In addition to the PPC64 signal frame itself being of misaligned size,
the explicit alignment of the starting stack pointer is also to 8
instead of 16. I've corrected this as well, so signal frames are
aligned even if the interrupted registers contained a misaligned stack
pointer.
