The commit
1155de4 ring-buffer: Make it generally available
already made ring-buffer available without the TRACING option
enabled. This patch removes the TRACING dependency from oprofile.Fixes also oprofile configuration on ia64.
The patch also applies to the 2.6.32-stable kernel.

Replace the zero-division warning message with WARN_ON_ONCE() per the
advice by Linus. This shouldn't happen, but if it happens, it's
possible that the bug happens often due to buggy IRQs.Signed-off-by: Takashi Iwai

Mike Frysinger pointed out that calling tracehook_signal_handler with
stepping=0 missed testing the thread flags, resulting in not calling
ptrace_notify. Fix this by testing if we're single stepping or branch
stepping and setting the flag accordingly.Tested, seems to work.

If the regulator constraints are empty and there is no voltage
reported then nothing will be added to the text displayed for the
constraints, leading to random stack data being printed. This is
unlikely to happen for practical regulators since most will at
least report a voltage but should still be fixed.Signed-off-by: Mark Brown

This patch solves a corner case during allocation which occurs if both
metadata (indirect) and data blocks are required but there is an
obstacle in the filesystem (e.g. a resource group header or another
allocated block) such that when the allocation is requested only
enough blocks for the metadata are returned.By changing the exit condition of this loop, we ensure that a
minimum of one data block will always be returned.Signed-off-by: Steven Whitehouse

When reserving stack space for a new process, make sure we're not
attempting to expand the stack by more than rlimit allows.This fixes a bug caused by b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm:
variable length argument support") and unmasked by
fc63cf237078c86214abcb2ee9926d8ad289da9b ("exec: setup_arg_pages() fails
to return errors").This bug means that when limiting the stack to less the 20*PAGE_SIZE (eg.
80K on 4K pages or 'ulimit -s 79') all processes will be killed before
they start. This is particularly bad with 64K pages, where a ulimit below
1280K will kill every process.To test, do:
'ulimit -s 15; ls'
before and after the patch is applied. Before it's applied, 'ls' should
be killed. After the patch is applied, 'ls' should no longer be killed.A stack limit of 15KB since it's small enough to trigger 20*PAGE_SIZE.
Also 15KB not a multiple of PAGE_SIZE, which is a trickier case to handle
correctly with this code.4K pages should be fine to test with.

Commit b4846251727a38a7f248e41308c060995371dd05 ("edac: mpc85xx add
mpc83xx support") accidentally broke how a chip select's first and last
page addresses are calculated. The page addresses are being shifted too
far right by PAGE_SHIFT. This results in errors such as:EDAC MPC85xx MC1: Err addr: 0x003075c0
EDAC MPC85xx MC1: PFN: 0x00000307
EDAC MPC85xx MC1: PFN out of range!
EDAC MC1: INTERNAL ERROR: row out of range (4 >= 4)
EDAC MC1: CE - no information available: INTERNAL ERRORThe vaule of PAGE_SHIFT is already being taken into consideration during
the calculation of the 'start' and 'end' variables, thus it is not
necessary to account for it again when setting a chip select's first and

This patch fixes a bug in the multiblock write tests where the written
data is read back for verifying one block at a time. The tests in
mmc_test assumes that all cards are byte addressable.This will cause the multi block write tests to fail, leading the user of
the mmc_test driver thinking there is something wrong with the sdhci
driver they are testing.The start address for the block is calculated as: blocknum * 512. For
block addressable cards the blocknum alone should be used.Signed-off-by: Johan Kristell

When suspending, tpm_infineon calls the generic suspend function of the

hangs upon suspend. When sending the necessary command "TPM_SaveState"

An unfortunate "WARNING" in the message amd64_edac dumps when the system
doesn't support DRAM ECC or ECC checking is not enabled in the BIOS
used to trigger kerneloops which qualified the message as an OOPS thus
misleading the users. See, e.g.https://bugs.launchpad.net/ubuntu/+source/linux/+bug/422536
http://bugzilla.kernel.org/show_bug.cgi?id=15238Downgrade the message level to KERN_NOTICE and fix the formulation.

This patch corrects a userspace pointer dereference in the VGA arbiter
in 2.6.32.1.copy_from_user() is used at line 822 to copy the contents of buf into
kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf. This
problem led to a GPF in strncmp() when X was started on my x86_32 systems.
X triggered the behavior with a write of "target PCI:0000:01:00.0" to
/dev/vga_arbiter.The patch has been tested against 2.6.32.1 and observed to correct the GPF
observed when starting X or manually writing the string "target
PCI:0000:01:00.0" to /dev/vga_arbiter.Signed-off-by: Andy Getzendanner
