for_each_cpu() actually iterates across all possible CPUs. We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs. This is inefficient and
possibly buggy.We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.This patch replaces for_each_cpu with for_each_possible_cpu.

Patch from Lennert Buytenhek
The irq2gpio array was recently converted from an array of ints to an
array of chars (by patch 3368/1.) However, this array contains elements
that are -1, and on ARM, the char type is unsigned by default, so this
patch broke the GPIO check in ixp4xx_set_irq_type.Change the 'char' to be a 'signed char' to fix this.

AMD K7/K8 CPUs only save/restore the FOP/FIP/FDP x87 registers in FXSAVE
when an exception is pending. This means the value leak through
context switches and allow processes to observe some x87 instruction
state of other processes.This was actually documented by AMD, but nobody recognized it as
being different from Intel before.The fix first adds an optimization: instead of unconditionally
calling FNCLEX after each FXSAVE test if ES is pending and skip
it when not needed. Then do a x87 load from a kernel variable to
clear FOP/FIP/FDP.This means other processes always will only see a constant value
defined by the kernel in their FP state.I took some pain to make sure to chose a variable that's already
in L1 during context switch to make the overhead of this low.Also alternative() is used to patch away the new code on CPUs
who don't need it.Patch for both i386/x86-64.
The problem was discovered originally by Jan Beulich. Richard
Brunner provided the basic code for the workarounds, with contribution
from Jan.This is CVE-2006-1056

This fixes a hang in mpu401_uart.c that can occur when the mpu401 interface
is non-existent or otherwise doesn't respond to commands but we issue IO
anyway. snd_mpu401_uart_cmd now returns an error code that is passed up
the stack so that an open() will fail immediately in such cases.Eventually discovered after wine/cxoffice would constantly cause hard
lockups on my desktop immediately after loading (emulating Windows too
well). Turned out that I'd recently moved my sound cards around and using
/dev/sequencer now talks to a sound card with a broken MPU.This second version changes -EFAULT to -EIO and frees open resources on
error too. Test booted and seems to work ok.Signed-off-by: Jon Masters

Fix for bug #6395:
Fail to resume on Tecra M2 with ADM1032 and Intel 82801DBM
The BIOS of the Tecra M2 doesn't like it when it has to reboot or resume
after the i2c-i801 driver has left the SMBus in PEC mode. The most simple
fix is to clear the PEC bit after after every transaction. That's what
this driver was doing up to 2.6.15 (inclusive).Thanks to Daniele Gaffuri for the very good report.

On the MSI-K8T-NEO2 FIR ( Athlon-64, Socket 939 with VIA-K8T800- Chipset
and onboard Sound,... ) the BIOS lets you choose "DISABLED" or "AUTO" for
the On-Board Sound Device.If you add another PCI-Sound-Card the BIOS disables the on-board device.
So far I have a Quirk, that does set the correspondent BIT in the
PCI-registers to enable the soundcard.But how to ensure that the code is executed ONLY on excactly this kind of
boards (not any other with similar Chipset)?Cc: Jaroslav Kysela

…ences and other cleanups
During module unloading, cdev_del() must be called to unmap cdev related
kobject references and other cleanups(such as inode->i_cdev being set to
NULL) which prevents the OOPS upon subsequent loading, usage and unloading
of modules(as seen in the mail thread
http://marc.theaimsgroup.com/?l=linux-kernel&m=114533640609018&w=2).Also, remove unneeded test of gpio_base.

In cases where a struct kretprobe's *_handler fields are non-NULL, it is
possible to cause a system crash, due to the possibility of calls ending up
in zombie functions. Documentation clearly states that unused *_handlers
should be set to NULL, but kprobe users sometimes fail to do so.Fix it by setting the non-relevant fields of the struct kretprobe to NULL.

Add some sanity checking. truesize should be at least sizeof(struct
sk_buff) plus the current packet length. If not, then truesize is
seriously mangled and deserves a kernel log message.Currently we'll do the check for release of stream socket buffers.
But we can add checks to more spots over time.
