Use ACPI _PSS data to determine valid frequency and voltage pairs on Enhanced
SpeedStep-capable processors. An original form of such ACPI-PentiumM-cpufreq
interaction was sent to the cpufreq list by David Moore in June last year; the
attached patch utilizes his code to set _PDC.
                                                                                                   
The new ACPI "P-States library" is utilized to obtain the correct frequency
and MSR value pairs for the speedstep-centrino driver. Only if no such proper
table exists (!CONFIG_ACPI, broken ACPI tables, etc.), fall back to the
existing hard-coded table.
                                                                                                   
If anyone has a better idea for the Kconfig section, please tell me so.
                                                                                                   
This version of this patch has proper acpi_state setting included, and also
has a hint in the banner of the centrino_cpu_init_acpi() function, as Jeremey
Fitzhardinge suggested.

Only the FEATURE_EST bit for CPU 0 is checked in module_init() directly.
As cpufreq drivers aren't sticky any longer (see previous patch),
this will not change user-visible behaviour.

Some cpufreq drivers can only tell whether they work while the per-CPU
->init() function is executed [e.g. the acpi driver]. So that cpufreq_driver
isn't blocked by such stale drivers, unload them unless the driver sets a
special flag.

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.

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.

Current Linus tree adds an extra space and dot to the mkprep options.

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.

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.

there.  This brings devices.txt up-to-date with LANANA.

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

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.
