Michael Kerrisk found out that signalfd was not reporting back user data
pushed using sigqueue:
http://groups.google.com/group/linux.kernel/msg/9397cab8551e3123
The following patch makes signalfd report back the ssi_ptr and ssi_int members
of the signalfd_siginfo structure.

Increase the PNP "number of devices" limit. We currently use an unsigned
char, which limits us to 256 devices per protocol. This patch changes that to
an unsigned int.
Not all backends can take advantage of this: we limit ISAPNP to 10 devices in
isapnp_cfg_begin(), and PNPBIOS is limited to 256 devices because the BIOS
interfaces use a one-byte device node number.
But there is no limit on the number of PNPACPI devices we may have. Large HP
Integrity machines have more than 256, which causes the current "unsigned char
number" to wrap around. This causes errors like this:
pnp: PnP ACPI init
kobject_add failed for 00:00 with -EEXIST, don't try to register things with the same name in the same directory.

This patch increases the limit to fix this PNPACPI problem. It should not
have any adverse effect on ISAPNP or PNPBIOS because their limits are still
enforced in the backends.

If a failure is detected after a parity check operation has been initiated,
but before it completes handle_parity_checks5 will never quiesce operations on
the stripe.
Explicitly handle this case by "canceling" the parity check, i.e. clear the
STRIPE_OP_CHECK flags and queue the stripe on the handle list again to refresh
any non-uptodate blocks.
Kernel versions >= 2.6.23 are susceptible.

Jeff Roberson discovered a race when using kaio eventfd based notifications.
When it occurs it can lead tomissed wakeups and hung userspace.
This patch fixes the race by moving the notification inside the spinlocked
section of kaio. The operation is safe since eventfd spinlock and kaio one
are unrelated.

Extend the /proc/<pid>/cgroup file to include the appropriate hierarchy ID on
each line.
Currently this ID isn't really needed since a hierarchy can be completely
identified by the set of subsystems bound to it, but this is likely to change
in the near future in order to support stateless subsystems and
merging/rebinding of subsystems. Getting this change into 2.6.25 reduces the
need for an API change later.

It's really a pretty ugly thing to need, and some day it will hopefully
be obviated by teaching gcc about the magic calling conventions for the
low-level system call code, but in the meantime we can at least add big
honking comments about why we need these insane and strange macros.
I took my comments from my version of the macro, but I ended up deciding
to just pick Roland's version of the actual code instead (with his
prettier syntax that uses vararg macros). Thus the previous two commits
that actually implement it.

Use asmlinkage_protect in sys_io_getevents, because GCC for i386 with
CONFIG_FRAME_POINTER=n can decide to clobber an argument word on the
stack, i.e. the user struct pt_regs. Here the problem is not a tail
call, but just the compiler's use of the stack when it inlines and
optimizes the body of the called function. This seems to avoid it.

The prevent_tail_call() macro works around the problem of the compiler
clobbering argument words on the stack, which for asmlinkage functions
is the caller's (user's) struct pt_regs. The tail/sibling-call
optimization is not the only way that the compiler can decide to use
stack argument words as scratch space, which we have to prevent.
Other optimizations can do it too.
Until we have new compiler support to make "asmlinkage" binding on the
compiler's own use of the stack argument frame, we have work around all
the manifestations of this issue that crop up.
More cases seem to be prevented by also keeping the incoming argument
variables live at the end of the function. This makes their original
stack slots attractive places to leave those variables, so the compiler
tends not clobber them for something else. It's still no guarantee, but
it handles some observed cases that prevent_tail_call() did not.

This patch also resolves hangs on boot:
http://lkml.org/lkml/2008/2/23/263
http://bugzilla.kernel.org/show_bug.cgi?id=10093
The bug was causing once-in-few-reboots 10-15 sec wait during boot on
certain laptops.
Earlier commit 40d6a146629b98d8e322b6f9332b182c7cbff3df added
smp_call_function in cpu_idle_wait() to kick cpus that are in tickless
idle. Looking at cpu_idle_wait code at that time, code seemed to be
over-engineered for a case which is rarely used (while changing idle
handler).
Below is a simplified version of cpu_idle_wait, which just makes a dummy
smp_call_function to all cpus, to make them come out of old idle handler
and start using the new idle handler. It eliminates code in the idle
loop to handle cpu_idle_wait.

Handle update_mmu_cache() being called when current->mm is NULL.
We cache static TLB mappings for the current page table in DAMPR4 and DAMPR5
on the theory that the next data lookup is likely to be in the same general
region, and thus is likely to be mapped by the same page table. However, we
can't get this information if we can't access the appropriate mm_struct.
If current->mm is NULL, we just clear the cache in the knowledge that the TLB
miss handlers will load it.

This fixes kernel bugzilla 10371.
As reported by M.Piechaczek@osmosys.tv, if we try to grab a
char sized socket option value, as in:
unsigned char ttl = 255;
socklen_t len = sizeof(ttl);
setsockopt(socket, IPPROTO_IP, IP_MULTICAST_TTL, &ttl, &len);
getsockopt(socket, IPPROTO_IP, IP_MULTICAST_TTL, &ttl, &len);
The ttl returned will be wrong on big-endian, and on both little-
endian and big-endian the next three bytes in userspace are written
with garbage.
It's because of this test in do_ip_getsockopt():
if (len < sizeof(int) && len > 0 && val>=0 && val<255) {
It should allow a 'val' of 255 to pass here, but it doesn't so it
copies a full 'int' back to userspace.
On little-endian that will write the correct value into the location
but it spams on the next three bytes in userspace. On big endian it
writes the wrong value into the location and spams the next three
bytes.

When switching scheduler from cfq, cfq_exit_queue() does not clear
ioc->ioc_data, leaving a dangling pointer that can deceive the following
lookups when the iosched is switched back to cfq. The pattern that can
trigger that is the following:
- elevator switch from cfq to something else;
- module unloading, with elv_unregister() that calls cfq_free_io_context()
on ioc freeing the cic (via the .trim op);
- module gets reloaded and the elevator switches back to cfq;
- reallocation of a cic at the same address as before (with a valid key).
To fix it just assign NULL to ioc_data in __cfq_exit_single_io_context(),
that is called from the regular exit path and from the elevator switching
code. The only path that frees a cic and is not covered is the error handling
one, but cic's freed in this way are never cached in ioc_data.

Since older kernels may look in the sb_bad_features2 slot for flags,
rather than zeroing it out on fixup, we should make it equal to the
sb_features2 value.
Also, if the ATTR2 flag was not found prior to features2 fixup, it was not
set in the mount flags, so re-check after the fixup so that the current
session will use the feature.
Also fix up the comments to reflect these changes.

Due to the xfs_dsb_t structure not being 64 bit aligned, the last field of
the on-disk superblock can vary in location This causes problems when the
filesystem gets moved to a different platform, or there is a 32 bit

This patch detects the defect at mount time, logs a warning such as:

in dmesg and corrects the problem so that everything is OK. it also
blacklists the bad field in the superblock so it does not get used for
something else later on.

1) ptrace should pass 'current' to task_user_regset_view()
2) When fetching general registers using a 64-bit view, and
the target is 32-bit, we have to convert.
3) Skip the whole register window get/set code block if
the user isn't asking to access anything in there.
Otherwise we have problems if the user doesn't have
an address space setup. Fetching ptrace register is
still valid at such a time, and ptrace does not try
to access the register window area of the regset.

gcc expects all toplevel assembly to return to the original section type.
The code in alteranative.c does not do this. This caused some strange bugs
in sched-devel where code would end up in the .rodata section and when
the kernel sets the NX bit on all .rodata, the kernel would crash when
executing this code.
This patch adds a .previous marker to return the code back to the
original section.
Credit goes to Andrew Pinski for telling me it wasn't a gcc bug but a
bug in the toplevel asm code in the kernel. ;-)

This patch restores the initialization, fixing openswan, but probably

case, disable protection and use short preamble mode as specified in
capability field. The same is done if capability field is changed on-the-fly.

Commit 0f436eff54f90419ac1b8accfb3e6e17c4b49a4e breaks build on
arch/ppc as it doesn't implement the machine_is() macro.
This fixes it by using CONFIG_PPC_MERGE instead which represents
arch/powerpc only, while CONFIG_PPC is set for both.
