To allow various options to work per-mount instead of per-sb we need a
struct vfsmount when updating ctime and mtime. This preparation patch
replaces the inode_update_time routine with a file_update_atime routine so
we can easily get at the vfsmount. (and the file makes more sense in this
context anyway). Also get rid of the unused second argument - we always
want to update the ctime when calling this routine.

The xattr code has rather complex permission checks because the rules are very
different for different attribute namespaces. This patch moves as much as we
can into the generic code. Currently all the major disk based filesystems
duplicate these checks, while many minor filesystems or network filesystems
lack some or all of them.
To do this we need defines for the extended attribute names in common code, I
moved them up from JFS which had the nicest defintions.

- Saving the cpu registers of all cpus before booting in to the crash
kernel.
- crash_setup_regs will save the registers of the cpu on which panic has
occured. One of the concerns ppc64 folks raised is that after capturing the
register states, one should not pop the current call frame and push new one.
Hence it has been inlined. More call frames later get pushed on to stack
(machine_crash_shutdown() and machine_kexec()), but one will not want to
backtrace those.
- Not very sure about the CFI annotations. With this patch I am getting
decent backtrace with gdb. Assuming, compiler has generated enough
debugging information for crash_kexec(). Coding crash_setup_regs() in pure
assembly makes it tricky because then it can not be inlined and we don't
want to return back after capturing register states we don't want to pop
this call frame.
- Saving the non-panicing cpus registers will be done in the NMI handler
while shooting down them in machine_crash_shutdown.

- If system panics then cpu register states are captured through funciton
crash_get_current_regs(). This is not a inline function hence a stack frame
is pushed on to the stack and then cpu register state is captured. Later
this frame is popped and new frames are pushed (machine_kexec).
- In theory this is not very right as we are capturing register states for a
frame and that frame is no more valid. This seems to have created back
trace problems for ppc64.
- This patch fixes it up. The very first thing it does after entering
crash_kexec() is to capture the register states. Anyway we don't want the
back trace beyond crash_kexec(). crash_get_current_regs() has been made
inline
- crash_setup_regs() is the top architecture dependent function which should
be responsible for capturing the register states as well as to do some
architecture dependent tricks. For ex. fixing up ss and esp for i386.
crash_setup_regs() has also been made inline to ensure no new call frame is
pushed onto stack.

- In case of system crash, current state of cpu registers is saved in memory
in elf note format. So far memory for storing elf notes was being allocated
statically for NR_CPUS.
- This patch introduces dynamic allocation of memory for storing elf notes.
It uses alloc_percpu() interface. This should lead to better memory usage.
- Introduced based on Andi Kleen's and Eric W. Biederman's suggestions.
- This patch also moves memory allocation for elf notes from architecture
dependent portion to architecture independent portion. Now crash_notes is
architecture independent. The whole idea is that size of memory to be

allocation of this memory can be architecture independent.

This is the first step on the road towards asynchronous support in
the Crypto API. It adds support for having multiple crypto_alg objects
for the same algorithm registered in the system.
For example, each device driver would register a crypto_alg object
for each algorithm that it supports. While at the same time the
user may load software implementations of those same algorithms.
Users of the Crypto API may then select a specific implementation
by name, or choose any implementation for a given algorithm with
the highest priority.
The priority field is a 32-bit signed integer. In future it will be
possible to modify it from user-space.

Patch from Deepak Saxena
In working on adding 36-bit addressed supersection support to ioremap(),
I came to the conclusion that it would be far simpler to do so by just
splitting __ioremap() into a main external interface and adding an
__ioremap_pfn() function that takes a pfn + offset into the page that
__ioremap() can call. This way existing callers of __ioremap() won't have
to change their code and 36-bit systems will just call __ioremap_pfn()
and we will not have to deal with unsigned long long variables.
Note that __ioremap_pfn() should _NOT_ be called directly by drivers
but is reserved for use by arch_ioremap() implementations that map
32-bit resource regions into the real 36-bit address and then call
this new function.

This moves the 32 bit ioctl compatibility handlers for
Video4Linux into a new file and adds explicit calls to them
to each v4l device driver.
Unfortunately, there does not seem to be any code handling
the v4l2 ioctls, so quite often the code goes through two
separate conversions, first from 32 bit v4l to 64 bit v4l,
and from there to 64 bit v4l2. My patch does not change
that, so there is still much room for improvement.
Also, some drivers have additional ioctl numbers, for
which the conversion should be handled internally to
that driver.

Patch from SAN People
Following changes were made to clock.c:
1) Replaced <asm/hardware/clock.h> with <linux/clk.h>
2) Removed old unused clk_enable & clk_disable.
3) Replaced clk_use/clk_unuse with clk_enable/clk_disable.
Otherwise it's the same as the previous patch.

This patch makes IDE use the new blk_complete_request() interface.
There's still room for improvement, as __ide_end_request() really
could drop the lock after getting HWGROUP->rq (why does it need to
hold it in the first place? If ->rq access isn't serialized, we are
screwed anyways).

This patch moves the SCSI softirq handling to the block layer version.
There should be no functional changes.
Signed-off-by: Jens Axboe <axboe@suse.de>
Request completion can be a quite heavy process, since it needs to
iterate through the entire request and complete the bio's it holds.
This patch adds blk_complete_request() which moves this processing
into a dedicated block softirq.

It's a broken interface, it's done way too late. And apparently it triggers
slab problems in recent kernels as well (most likely after the generic dispatch
code was merged). So kill it, ide-cd is the only user of it.

My recent changes to oprofile broke it when built as a module. Fix it by
using an enum instead of a function pointer. This way we still retain
the oprofile configuration in the cputable.

This is the platform function interpreter itself along with the backends
for UniN/U3/U4, mac-io, GPIOs and i2c. It adds the ability to execute
those do-platform-* scripts in the device-tree (at least for most
devices for which a backend is provided). This should replace the clock
spreading hacks properly. It might also have an impact on all sort of
machines since some of the scripts marked "at init" will now be executed
on boot (or some other on sleep/wakeup), those will possibly do things
that the kernel didn't do at all, like setting some values into some i2c
devices (changing thermal sensor calibration or conversion rate) etc...
Thus regression testing is MUCH welcome. Also loook for errors in dmesg.
That's also why I've left rather verbose debugging enabled in this
version of the patch.
(I do expect some Windtunnel G4s to show some errors as they have an i2c
clock chip on the PMU bus that uses some primitives that the i2c backend
doesn't implement yet. I really need users that have one of those
machine to come back to me so we can get that done right, though the
errors themselves should be harmless, I suspect the machine might not
run at full speed).
