After discussing it with Neil, he fell that the original justification for
taking the kernel_lock on find_exported_dentry() is not longer valid and
should be safe to remove.

This patch fixes an issue while running SpecSFS where under memory
pressure, shrinking dcache cause find_exported_dentry() to allocate
disconnected dentries that later needed to be properly connected.  The
connecting part of the code was done with BKL taken which cause a sharp
drop in performance during iterations and profiles showing 75% time spent
on find_exported_dentry().  After applying the patch, time spent on the
function is reduce to <1%.

I have tested this on an 8-way machine with 56 filesystems for several days
now with no problems using ext2, ext3, xfs and jfs.

Don't panic if the journal superblock is wrecked: just fail the mount.

arch/ppc64/Kconfig's entry for CONFIG_PREEMPT is missing the description
after the "bool" statement, so the entry does not show up.

Also, the help description mentions a restriction that is not [any longer]
true.

- remove now unused kernel syscalls.
- wrap recently added defines in #ifdef __KERNEL__, fixes glibc
  compile issue
- some of our extra syscalls used asmlinkage, some did not. Make them
  consistent

The following patch comes from Paul Mackerras.  Earlier on in 2.6,
arch/ppc/boot/utils/mkprep.c was changed slightly so that it would build
and work on Solaris.  Doing this required changing from filling out
pointers to an area to filling out a local copy of the struct.  However, a
memcpy was left out, and the info is only needed on some machines to boot.
The following adds in the missing memcpy and allows for IBM PRePs to boot
from a raw floppy again.

From: Olaf Hering <olh@suse.de>

Current Linus tree adds an extra space and dot to the mkprep options.
`make all' with an smp config doesnt work.  This patch fixes it.

Please apply this fix to backout an erroneous change in loopback.c
The statistics structure is allocated separately from the
loopback_dev structure, and the current code overwrites something
other than the statistics.  In my case the scsi_cmd_pool structure.

The attached patch fixes the problem: de->macmode variable,
meant to shadow MacMode (CSR6) register, was used inconsistently,
causing some updates to this register to be dropped.

2.4 kernel doesn't shadow this register at all, so I removed
shadowing from 2.6 as well.

Without this change, GCC thinks it's OK to clobber r13.  It doesn't do it
very often, but it's enough if it does it once and it turns out
acpi_bus_receive_event() had code that would trigger this issue.
Fix by declaring r13 as a global register variable.

All users of hwif->mmio correctly handle resources themselves
(hwif->mmio == 2) so remove ide_mmio_dma() and ide_release_mmio_dma().

Nowadays buddha.c, gayle.c and macide.c handle resources themselves
(hwif->mmio == 2).

Acked by Geert.

It's write-only these days.

Here is the ChangeLog:

	* wireless/Kconfig: fix typos, add SMC2835W-V2
	* islpci_hotplug.c: new version 1.1, authors list, and
	module description updated appropriately
	* isl_ioctl.c, islpci_dev.c, 
	islpci_eth.c, islpci_hotplug.c, islpci_mgt.c: 
	s/ndev->priv/netdev_priv(ndev)/g
	* islpci_hotplug.c: Add PCI ID values for SMC2835W-V2 cardbus card
	Patch by Manuel Lauss <manuel.lauss@fh-hagenberg.at>
	* isl_38xx.[ch]: include firmware.h in header, remove
	declaration of headers in c file. Fix compiler warnings.
	* islpci_dev.c (islpci_alloc_memory),
	* islpci_eth.c (islpci_eth_cleanup_transmit, 
	islpci_eth_transmit, islpci_eth_receive): deal with skb stray 
	pointer, declare NULL.
	* isl_38xx.c: remove unecessary __KERNEL_SYSCALLS__ and
	re-ordered headers per vger.kernel.org - liking.
	* isl_ioctl.c, islpci_mgt.c: move from MODULE_PARAM to the new
	module_param, which is type-safe. Includes the new 
	<linux/moduleparam.h>.
	* isl_ioctl.c (prism54_[s|g]et_[maxframeburst|profile]): added.
	Not adding ioctls as ajfa is working on moving current private ioctls
	to subioctls.
	* isl_oid.h (dot11_[maxframeburst|preamblesettings|
	slotsettings|nonerpstatus|nonerpprotection]_t): added.
	Note: more ioctls can be added here, I believe problems
	with mixed modes can be pinpointed here, with these values.

Wider range for 33MHz timing and PLL setup for HPT374

cdu31a.c needs tmp_irq outside of the block it is declared in.  Move it

These options are only ever referenced in the defconfigs of various archs
now.

The current Linux implementation of shmat() insists on SHMLBA alignment even
when shmflg & SHM_RND == 0.  This is not consistent with the man pages and
the single UNIX spec, which require only a page-aligned address.

However, some architectures require a SHMLBA alignment for correctness in all
cases.  Such architectures use __ARCH_FORCE_SHMLBA.

Patch 3 adds all the new official device registrations that weren't already
there.  This brings devices.txt up-to-date with LANANA.

From: "Cagle, John (ISS-Houston)" <john.cagle@hp.com>

Patch 2 fixes some typos in devices.txt and removes ancient devices never
used.  Pretty obvious stuff.

From: "Cagle, John (ISS-Houston)" <john.cagle@hp.com>

Patch 1 cleans up the format by making devices.txt easily parsable.
Mainly this involved adding the word "block" after all the block major
numbers since the previous format didn't include it.

Make the handling of the hugetlb-backed shm file's name counter SMP-safe.

(What stops hugetlb_zero_setup() racing with umount?)

From: "Kenneth Chen" <kenneth.w.chen@intel.com>

Even though there is a CONFIG_MAX_RAW_DEVS option, it doesn't actually
increase the number of raw devices beyond 256 because during the char
registration, it uses the standard register_chrdev() interface which has
hard coded 256 minor in it.  Here is a patch that fix this problem by using
register_chrdev_region() and cdev_(init/add/del) functions.

From: Andy Whitcroft <andyw@uk.ibm.com>

The vsyscall implementation for ia32 provides two different vsyscall pages;
one to use int80 and the other to use sysenter.  Each includes a common
signal trailer.  The kernel requires the alignment of routines in this
trailer be consistent in both copies.  However this is not enforced at
compile time.  Failure to maintain this alignment typically leads to an
obscure SIGSEGV in init during boot.  This critical alignment requirement
is not well documented.

Below is a patch to better document the alignment requirements and to
enforce the requirement.
