BKL shifted into ->rmdir()

BKL shifted into ->mkdir()

This patch fixes a bug in the Linux process ID allocator.  It isn't quite
SMP safe since it references "last_pid" after releasing the lock protecting
it.  This can result in two processes getting assigned the same process ID.

this is the NeoMagic floating foint removal patch
I posted previously for Linux 2.4.18-pre9-ac3.

This final patch is a simple documentation fixup patch filling
in the blanks for the extended attribute interfaces; and fixes
a typo in the same spot: "permission".

Nathan

This next incremental patch tidies up the data types passed back
from the `list' and `get' extended attribute syscalls - these now
match the design (ie. using ssize_t) rather than simply using long
or int everywhere; also now use const types in the VFS interface,
where appropriate.

Nathan

This incremental patch fixes copying out of an extended attribute
value or name list.  Previously we copied out the entire buffer
passed in from userspace, now we only copy out the size which the
underlying filesystem tells us to (ie. we will no longer include
potentialy-initialised data as well).

Nathan

This first patch fixes the copying in of extended attribute
names from userspace in the extended attribute syscalls (a
problem found when using electric fence on the user tools).

	- fix for memory leak.

	- special case for REQUEST_SENSE

The patch below fixes a compile problem in the USB OHCI HCD driver on
powerbooks, namely that the ohci_hcd structure doesn't have an irq
member.

	Next one in the series - this time it's ->unlink()...

1) proc/<pid>/fd readdir() has broken locking - sometimes it ends up with
task->files->file_lock locked.

2) missing variable definition in arch/s390x/kernel/linux32.c::cp_new_stat32().

Please, apply - the first one is really serious.

	BKL held around ->i_nlink changes in ext2/namei.c.  That makes
namei.c SMP-safe (dir.c already is).  BKL dropped around ext2_free_inode() -
it's already SMP-safe (the only place that needed BKL was DQUOT_FREE_INODE()
and it got BKL in the previous patch).

	BKL shifted into ->create().  lock_kernel()/unlock_kernel() added
in dquot_{alloc,free}_inode() - that makes {ext2,minix,sysv,ufs}_read_inode()
SMP-safe.

	ext2_read_inode() and ext2_update_inode() share large chunk
of code - getting a buffer_head with raw inode in it.
	Moved into a helper function (ext2_get_inode()), the rest
of ext2_{read,update}_inode() slightly cleaned up.

fs/proc/inode.c is using __init, but for some reason missing an
#include <linux/init.h>. Add this.

Add Andi Kleen as x86-64 maintainer.

This adds the x86_64 arch and asm directories and a Documentation/x86_64.

It took a bit longer because I first had to make preemption and thread_info
work and also found some other bugs while doing this. The port has been
tested for a long time on UP.

I'm not sure what I should describe.  A lot is based on i386 with
a lot of cleanups. I wrote a paper about it for last year's OLS that describes
most of the changes (ftp://ftp.firstfloor.org/pub/ak/x86_64.ps.gz). It is
a bit outdated now, but should give a good overview.

It currently has a completely cut'n'pasted from others+hacked 32bit
emulation. I hope to clean that up in the future by merging the generic
core of this with other 64bit archs.

Thanks,

Just an gcc 3.1 warning fix. It now warns about __FUNCTION__ string
concatenation. Also remove the check because it does not seem to trigger
ever.

for the definition of unlikely().

The patch below changes access_process_vm to use a new architecture
hook, flush_icache_user_range, instead of flush_icache_page, and adds
a definition of flush_icache_user_range which does the same thing as
flush_icache_page for all architectures except PPC.  (The PPC update
that is in Linus' BK tree already includes a suitable definition of
flush_icache_user_range.)

The reason for doing this is that when flush_icache_page is called
from do_no_page or do_swap_page, I want to be able to do the flush
conditionally, based on the state of the page.  In contrast,
access_process_vm needs to do the flush unconditionally since it has
just modified the page.  In the access_process_vm case it is useful to
have the information about the user address and length that have been
modified since then we can just flush the affected cache lines rather
than the whole page.

This patch should make it easy to improve performance on alpha, since
there (as I understand it) the icache flush is not needed at all in
do_no_page or do_swap_page, but is needed in access_process_vm.  All
that is needed is to make flush_icache_page a noop on alpha.  The
patch below doesn't do this, I'll let the alpha maintainers push that
change if they want.

This patch fixes a compile error on PPC.  It's in sd_find_target, a
function that returns a kdev_t.
