The size argument to zalloc should be the size of desired
structure, not the pointer to it.

After the merge of the IO controller patches, booting on my megaraid
box ran much slower. Vivek Goyal traced it down to megaraid discovery
creating tons of devices, each suffering a grace period when they later
kill that queue (if no device is found).
So lets use call_rcu() to batch these deferred frees, instead of taking
the grace period hit for each one.

In ____cache_alloc(), the variable 'ac' may be changed after
cache_alloc_refill() and the following kmemleak_erase() may get an incorrect
pointer. Update 'ac' after cache_alloc_refill() unconditionally.

Branch profiling on my nehalem machine showed 99% incorrect branch hints:

Discussion on lkml [1] led to the solution to remove this hint.

When we enter in irq, two things can happen to preserve the link
to the previous frame pointer:
- If we were in an irq already, we don't switch to the irq stack
as we are inside. We just need to save the previous frame
pointer and to link the new one to the previous.
- Otherwise we need another level of indirection. We enter the irq with
the previous stack. We save the previous bp inside and make bp
pointing to its saved address. Then we switch to the irq stack and
push bp another time but to the new stack. This makes two levels to
dereference instead of one.
In the second case, the current stacktrace code omits the second level
and loses the frame pointer accuracy. The stack that follows will then
be considered as unreliable.
Handling that makes the perf callchain happier.

While dumping a stacktrace, the end of the exception stack won't link
the frame pointer to the previous stack.
The interrupted stack will then be considered as unreliable and ignored
by perf, as the frame pointer is unreliable itself.
This happens because we overwrite the frame pointer that links to the
interrupted frame with the address of the exception stack. This is
done in order to reserve space inside.
But rbp has been chosen here only because it is not a scratch register,
so that the address of the exception stack remains in rbp after calling
do_debug(), we can then release the exception stack space without the
need to retrieve its address again.
But we can pick another non-scratch register to do that, so that we
preserve the link to the interrupted stack frame in the stacktraces.
Just randomly choose r12. Every registers are saved just before and
restored just after calling do_debug(). And r12 is not used in the
middle, which makes it a perfect candidate.
Example: perf record -g -a -c 1 -f -e mem:$(tasklist_lock_addr):rw

We are infected with all the debug stack. Like the nmi stack, the debug

struct perf_event::event callback was called when a breakpoint
triggers. But this is a rather opaque callback, pretty
tied-only to the breakpoint API and not really integrated into perf
as it triggers even when we don't overflow.
We prefer to use overflow_handler() as it fits into the perf events
rules, being called only when we overflow.

"ARCH" can be just about anything, so we shouldn't end up
with UTS_MACHINE of "sparc" in a 64-bit kernel build just
because someone set the personality using 'sparc32' or
similar. CONFIG_SPARC64 drives the compilation and
therefore provides the definitive value, not "ARCH".
This mirrors commit 8c6531f7a99f29ba8817ffb12cc9ecf190049bd6
(x86: correctly set UTS_MACHINE for "make ARCH=x86")

We no longer need to maintain a distinction between nfs41_sequence_done and

We should not assume that nfs41_init_clientid() will always want to
initialise the session. If it is being called due to a server reboot, then
we just want to reset the session after re-establishing the clientid.
Fix this by getting rid of the 'reset' parameter in
nfs4_proc_create_session(), and instead relying on whether or not the
session slot table pointer is non-NULL.

This patch invokes RECLAIM_COMPLETE after the client is done
reclaiming state.
There are interpretations of the spec that suggest that
RECLAIM_COMPLETE should also be issued after a new clientid
has been obtained from the server and even if there is no
state to reclaim. This tells the server that the client
has no state to reclaim even if the client isn't aware the
server may have rebooted.

Implements RECLAIM_COMPLETE as an asynchronous RPC.
NFS4ERR_DELAY is retried, NFS4ERR_DEADSESSION invokes the error handling
but does not result in a retry, since we don't want to have a lingering
RECLAIM_COMPLETE call sent in the middle of a possible new state recovery
cycle. If a session reset occurs, a new wave of reclaim operations will
follow, containing their own RECLAIM_COMPLETE call. We don't want a
retry to get on the way of recovery by incorrectly indicating to the
server that we're done reclaiming state.
A subsequent patch invokes the functionality.

This patch replace 64-bit division by do_div() macro and remove usage of
floating point variable

The same loop to seek for a key were used on different places. Also,
no spinlock were protecting it to avoid the risk of replacing a keycode
while seeking for a new code.
This cleanup does:
- create an unique function to seek for a code;
- adds an spinlock to protect the table lookup;
- remove some unused code;
- simplifies to code to make it easier to understand.
Basically no change in behavior should be noticed after this patch.

Currently, the IR table is initialized by calling ir_input_init(). However,
this function doesn't return any error code, nor has a function to be called
when de-initializing the IR's.
Change the return argment to integer and make sure that each driver will
handle the error code. Also adds a function to free any resources that may
be allocating there: ir_input_free().

Modifies the IR table for HVR-950 to use the newer Hauppauge RC5 table,
and adds the RC5 address to the functions that get the scancode for this
device.
It is easy to add support for all other RC5 IR's on em2880 boards, but
the scancode table needs to be re-generated. So, keep using the old
7bits tables while we don't have all tables converted.
Also, the 7bits tables are still used on other drivers, so this small
patch needs to be ported to all drivers.

Now that V4L drivers can support more than 7 bits for scan code, let's
add a modified version for the Hauppauge Grey IR containing the full IR
scancode.

Now that the IR conversion to dynamic tables has finished, we can get
rid of some fields and definitions that aren't used anymore.

V4L drivers use an static keycode vector with 128 entries, where the scancode
indexes the keycode. While this works, it limits the scancodes to have only
7 bits, not allowing for example full RC5 codes.
Instead of implementing the same code on every V4L driver, provide a common
infrastructure to handle the bigger tables, minimizing the changes inside
each driver.

As newer IR common code will be added on other files, we need a global
debug var inside the module.

Convert the go7007 driver to v4l2 subdev interface, using v4l2 i2c
subdev functions instead of i2c functions directly. The v4l2 ioctl ops
functions call subdev ops instead of i2c commands.

The s2250-board i2c module was converted to use v4l2-i2c-drv.h in
preparation for its subdev conversion. This change prevented the
s2250-loader from being initialized within the same module due to
the module_init and module_exit function definitions in v4l2-i2c-drv.h.
Therefore, s2250-loader is now its own module, and the header for
exporting s2250-loader functions is no longer needed.
The s2250 i2c module name was "2220-board" in some places, and was
changed to "s2250".
