Since sparse_index_alloc() can return NULL on memory allocation failure,

Ingo hit some BUG_ONs that were probably caused by these missing unlocks
causing an unbalance. He couldn't reproduce the bug reliably, so it's
unknown that it's definitly fixing the problem he hit, but it's a fairly
good chance, and this fixes an obvious bug.[ Dave: "Ingo followed up that he hit some lockdep related output with
this applied, so it may not be right. I'll look at it after
xmas if no-one has it figured out before then."
Akpm: "It looks pretty correct to me though." ]Signed-off-by: Dave Jones

This fixes some of the alpha-specific build problems, except a) modpost
warning about COMMON symbol "saved_config" and b) nasty final link
failure with gcc-4.x, -Os and scsi-disk driver configured built-in
(due to jump table in .rodata referencing discarded .exit.text).- build failure with gcc-4.2.x: fix up casts in cia_io* routines to avoid
warnings ('discards qualifiers from pointer target type'), which are
failures, thanks to -Werror;
- modpost warnings: add missing __init qualifier for titan and marvel;
for non-generic build, move machine vectors from .data to .data.init.refok
section;
- unbreak CPU-specific optimization: rearrange cpuflags-y assignments
so that extended -mcpu value (ev56, pca56, ev67) overrides basic
one (ev5, ev6) and not vice versa.Signed-off-by: Ivan Kokshaysky

As it turns out, the kernel divides by EXT3_INODES_PER_GROUP(s) when
mounting an ext3 filesystem. If that number is zero, a crash follows.
Below a patch.This crash was reported by Joeri de Ruiter, Carst Tankink and Pim Vullers.

SPARSEMEM_VMEMMAP needs to be a selectable config option to support
building the kernel both with and without sparsemem vmemmap support. This
selection is desirable for platforms which could be configured one way for

ecryptfs_destroy_mount_crypt_stat() checks whether each
auth_tok->global_auth_tok_key is nonzero and if so puts that key. However,
in some early mount error paths nothing has initialized the pointer, and we
try to key_put() garbage. Running the bad cipher tests in the testsuite
exposes this, and it's happy with the following change.Signed-off-by: Eric Sandeen

While auditing proc_doulongvec_ms_jiffies_minmax() usage in kernel, I found
a bug in drivers/parport/procfs.c, incorrectly using sizeof(int) instead of
sizeof(unsigned long)Only 64bit arches are affected by this old bug.

First of all, thanks to Bob Tracy and
Michael Cree for testing.
Especially to Bob, as he has done titanic multi-day git-bisect
work that finally helped to reproduce and nail down the bug
(http://bugzilla.kernel.org/show_bug.cgi?id=9457).[ev6-]stxncpy.S: it's t12, not t2 register that is supposed to contain
the last byte offset upon return. As a result of wrong register use
(which was my fault back in 2003, IIRC), under some circumstances extra
terminating zero bytes were added to destination string. This particularly
led to incorrect DEVPATH strings generated in uevent and therefore to udev
problems.strncpy.S: unrelated bug I found while testing the above fix - destination
is not properly zero-padded then a byte count exceeds source length.
Actually this is addition to strncpy fix from last year.Signed-off-by: Ivan Kokshaysky

Sometimes when UML is debugged gdb miss breakpoints.
When process traced by gdb do fork, debugger remove breakpoints from
child address space. There is possibility to trace more than one fork,
but this not work with UML, I guess (only guess) there is a deadlock -
gdb waits for UML and UML waits for gdb.When clone() is called with SIGCHLD and CLONE_VM flags, gdb see this
as PTRACE_EVENT_FORK not as PTRACE_EVENT_CLONE and remove breakpoints
from child and at the same time from traced process, because either
have the same address space.Maybe it is possible to do fix in gdb, but I'm not sure if there is
easy way to find out if traced and child processes share memory. So I
do fix for UML, it simply do not call clone() with both SIGCHLD and
CLONE_VM flags together. Additionally __WALL flag is used for
waitpid() to assure not miss clone and normal process events.[ jdike - checkpatch fixes ]

ocfs2_extend_trans() might call journal_restart() which will commit dirty
buffers and then restart the transaction. This means that any buffers which
still need changes should be passed to journal_access() again. Some paths
during extend weren't doing this right.Signed-off-by: Mark Fasheh
-
The nastiest cases of transaction extends are also the rarest. We can expose
them more quickly at the expense of performance by going straight to the
journal_restart() in ocfs2_extend_trans(). Wrap things in OCFS2_DEBUG_FS so
that we only do this when "expensive debugging" is turned on.Signed-off-by: Mark Fasheh

This reverts one change from 67fa10627ec0d8aa16f1cf38cf527e67d8097d3c
that prevented userspace from seing the "driver disk" lun in a san disk
device. The kernel shouldn't do this, it's up to userspace to handle
this properly, if it somehow wants to filter this away.Cc: Ben Collins

The OHCI IRQ handler has an optimisation that avoids reading some
chip registers when the controller reports that the interrupt was
triggered *only* because completed requests were written into the
controller's "done list" and handed to the host.This mechanism can't be used on some controllers. Among others, it
fails for the SA1111 and the AMCC 440EP PowerPC processor.This patch removes the optimisation and makes the code clearer.

Correct hanging while disconnecting the USB device cable. Prevent a race
between vbus and UDP interrupts. This bug was tracked on at91sam9260ek
boards.A usb resume interrupt was firing after the vbus interrupt : the IP was
then already stoped and not able to deal with it (no more clock). A simple
interrupt disabling is ok as the "end of bus reset" irq is non maskable and
ok to resume the USB device IP.Signed-off-by: Nicolas Ferre

Host controller IRQs are supposed to be serviced with interrupts
disabled. This patch (as1026) adds an IRQF_DISABLED flag to all the
controller drivers that lack it. It also replaces the
spin_lock_irqsave() and spin_unlock_irqrestore() calls in uhci_irq()
with simple spin_lock() and spin_unlock().This fixes Bugzilla #9335.

This adds a device ID for the Aerocomm Radio Modem, which uses the
cp2102. I'm sure changing num_bulk_in/num_bulk_out to NUM_DONT_CARE
is the wrong fix, but this is the only device I have with a cp2102,
so I have no idea what a good global value would be, if there is one.

When a device cannot handle the smallest previously limited transfer
size (64 blocks) without stalling, limit the device to the amount of
packets that fit in a platform native page.The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever
used on a platform that has larger than 8K pages, you lose unless you
can convince the device firmware folks to fix the issue.Cc: Mathew Dharm
