Patch from Hugh Dickins <hugh@veritas.com>

When prune_icache coincides with unmounting, invalidate_inodes notices
the inode it's working on as busy but doesn't wait: Self-destruct in 5
seconds message, and later iput oopses on freed super_block.

Neither end is a fast path, so the patch just adds iprune_sem for exclusion.

The semaphore is held across dispose_list so that
dispose_list->clear_inode->destroy_inode cannot reference a destroyed
superblock.

Patch from Rick Lindsley <ricklind@us.ibm.com>

Fixes a couple of odd cases in which disk requests were not being accounted
for.

This check is not needed - the PMD is known to be present.

Patch from Maneesh Soni <maneesh@in.ibm.com>

Turns out that sysfs is doing dget() on a zero-ref dentry.  That's a bug, but
dcache is no longer detecting it.

The check was removed because with lockless d_lookup, there can be cases when
d_lookup and dput are going on concurrently, If d_lookup happens earlier then
it may do dget() on a dentry for which dput() has decremented the ref count
to zero.  This race is handled by taking the per dentry lock and checking the
DCACHE_UNHASHED flag.

The patch open-codes that part of d_lookup(), and restores the BUG check in
dget().

Use interruptible sleep rather than uninterruptible to avoid perturbing load
average.

do_generic_mapping_read() has an open-coded version of find_get_page() hidden
inside it.

Use the early ioremap code to parse the Static Resource Affinity Table on
x440 machines.

Patch from Patricia Gaughen <gone@us.ibm.com>,
		Dave Hansen <haveblue@us.ibm.com>

It provides a very early sort of kmap-by-hand.

The patch is used by the x440 discontigmem to map the srat tables into low
memory so that the memory can be setup.  This remap function is used very
early in the boot process...  at the start of setup_arch().

This functionality is only available to Summit and NUMAQ.  It will work on
other platforms, but they do not need it.

Patch from Thomas Schlichter <schlicht@uni-mannheim.de>

Make flush_tlb_all() preempt-safe.  Same as the ia32 fix.

Patch from Joakim Tjernlund <joakim.tjernlund@lumentis.se>

Here is another update(against BK curr) for crc32(). A kind soul pointed out
the optimizations below.

lib/crc32defs.h:
 - Make it possible to define new values for CRC_LE_BITS/CRC_BE_BITS without
   modifying the source.

lib/crc32.c:
 - Eliminate the need for ENDIAN_SHIFT. Saves a 24 bit shift in the byte
   loops.

 - Swap the XOR expression in DO_CRC. gcc for x86 can not do that simple
   optimization itself(gcc 3.2.2 and RH gcc 2.96 tested). Will improve
   performance with 20-25% on x86.

Spotted by Anton Blanchard: Our attempt to limit the interrupts-off time in
slab wasn't very effective.  #ifndef DEBUG is never true.

Rework this function so that we only make the indirect call to the
page-freeing function on the final put_page(), rather than on every
invokation.

Patch from Hugh Dickins <hugh@veritas.com>

Userspace shows huge elapsed time across jiffies wrap: with USER_HZ less then
HZ, sys_times needs jiffies_64 to calculate its retval.

From Tim Schmielau <tim@physik3.uni-rostock.de>

Force jiffies to start out at five-minutes-before-wrap.  To find
jiffy-wrapping bugs.

make rpm has been broken in several kernel versions, fix it.  Solves
http://bugme.osdl.org/show_bug.cgi?id=373 which Paolo Ciarrocchi pushed
me to fix.

1) Moved make rpm to the noconfig section, thus allowing it to see
   the clean target.
2) Fixed the commandline for find
3) Use rpmbuild if present
4) In mkspec use the generic all target, and drop the dep target
   This made the build command arch independent

These are minor fixes for swsusp and S3 sleep.

 - #ifdef mess in acpi_save_state_mem() is simplified
 - better error handling in reserving bootmem
 - handle video bioses that play with segment registers
 - automagic support for S3 on toshiba notebook
 - don't try to sync() when pdflush is already stopped
 - reorder actions to make pdflush not complain

This converts /proc/io{mem,ports} to the seq_file interface
(single_open).

This patch fixes the incomplete data return problem of /proc/ide/triflex.
When the number of consecutive read bytes are smaller than the total
data in triflex_get_info(), the second read() returns 0.

Fixes for the 31 bit compatability layer:
 * add compat function for jiffies_to_timeval
 * convert parameters of clone system call
 * incorporate changes from setup_arg_pages to setup_arg_pages32
 * incorporate changes from do_execve to do_execve32
 * take care of nanosecond field in struct timespec
 * remove functions of old module system calls
 * add TIF_31BIT thread flag and replace S390_FLAG_31BIT with it
 * add arch_get_unmapped_area
 * add wrapper for sys_set_tid_address

Add missing/fix existing s390 relocations in the kernel module loader.
