lib: percpu_counter_sub
Hugh spotted that some code does:
percpu_counter_add(&counter, -unsignedlong)
which, when the amount argument is of type s32, sort-of works thanks to
two's-complement. However when we'd change the type to s64 this breaks on 32bit
machines, because the promotion rules zero extend the unsigned number.
Provide percpu_counter_sub() to hide the s64 cast. That is:
percpu_counter_sub(&counter, foo)
is equal to:
percpu_counter_add(&counter, -(s64)foo);

nfs: remove congestion_end()
These patches aim to improve balance_dirty_pages() and directly address three
issues:
1) inter device starvation
2) stacked device deadlocks
3) inter process starvation
1 and 2 are a direct result from removing the global dirty limit and using
per device dirty limits. By giving each device its own dirty limit is will
no longer starve another device, and the cyclic dependancy on the dirty limit
is broken.
In order to efficiently distribute the dirty limit across the independant
devices a floating proportion is used, this will allocate a share of the total
limit proportional to the device's recent activity.
3 is done by also scaling the dirty limit proportional to the current task's
recent dirty rate.
This patch:
nfs: remove congestion_end(). It's redundant, clear_bdi_congested() already
wakes the waiters.

powerpc: add Altivec/VMX state to coredumps
Update dump_task_altivec() (which has so far never been put to use) so that
it dumps the Altivec/VMX registers (VR[0] - VR[31], VSCR and VRSAVE) in the
same format as the ptrace get_vrregs(), and add the appropriate glue
typedef and #defines to make it work.
A new note type of NT_PPC_VMX was chosen to be 0x100 (arbitrarily) because
it allows the low range values to be used for more generic purposes and
0x100 seems an adequate starting point for PowerPC extensions.

x86: replace NT_PRXFPREG with ELF_CORE_XFPREG_TYPE #define
Replace NT_PRXFPREG with ELF_CORE_XFPREG_TYPE in the coredump code which
allows for more flexibility in the note type for the state of 'extended
floating point' implementations in coredumps. New note types can now be
added with an appropriate #define.
This does #define ELF_CORE_XFPREG_TYPE to be NT_PRXFPREG in all
current users so there's are no change in behaviour.
This will let us use different note types on powerpc for the Altivec/VMX

o the old __lookup_hash goes away, permission checks moves to

o useless inline qualifiers on above functions go away
- lookup_one_len_kern loses it's last argument and is renamed to

SELinux: improve performance when AVC misses.
* We add ebitmap_for_each_positive_bit() which enables to walk on
any positive bit on the given ebitmap, to improve its performance
using common bit-operations defined in linux/bitops.h.
In the previous version, this logic was implemented using a combination
of ebitmap_for_each_bit() and ebitmap_node_get_bit(), but is was worse
in performance aspect.
This logic is most frequestly used to compute a new AVC entry,
so this patch can improve SELinux performance when AVC misses are happen.
* struct ebitmap_node is redefined as an array of "unsigned long", to get
suitable for using find_next_bit() which is fasted than iteration of
shift and logical operation, and to maximize memory usage allocated

SELinux: policy selectable handling of unknown classes and perms
Allow policy to select, in much the same way as it selects MLS support, how
the kernel should handle access decisions which contain either unknown
classes or unknown permissions in known classes. The three choices for the
policy flags are
0 - Deny unknown security access. (default)
2 - reject loading policy if it does not contain all definitions
4 - allow unknown security access
The policy's choice is exported through 2 booleans in
selinuxfs. /selinux/deny_unknown and /selinux/reject_unknown.

This patch reduces memory usage of SELinux by tuning avtab. Number of hash

We now allocate a workqueue process exclusive to fw-sbp2. As a side

Remove ide_use_fast_pio() and just re-tune PIO unconditionally if DMA tuning
has failed in ->ide_dma_check. All host drivers using ide_use_fast_pio() set
drive->autotune so PIO is always tuned anyway and in some cases we _really_
need to re-tune PIO because PIO and DMA timings are shared.

au1xxx-ide: use ide_tune_dma()
* Remove needless setting of drive->using_dma from auide_dma_check().
* Split off auide_mdma_filter() from auide_dma_check().
* Use ide_tune_dma() in auide_dma_check(), this fixes following issues:
- device's DMA capability bit not being checked
- device not being checked against generic DMA blacklist
- transfer mode not being set on device/host
* Add PIO autotune fallback to auide_dma_check().

atiixp: DMA setup fixes
* Fix handling of unsupported/invalid modes in atiixp_set_dma_mode().
* ATI controllers allow separate PIO and DMA timings so remove programming
of PIO modes from atiixp_set_dma_mode(). Also remove no longer needed
atiixp_dma_2_pio() helper.
* SWDMA timings are not programmed by atiixp_set_dma_mode() and if SWDMA
mode is chosen atiixp_dma_host_on() erroneously enables UDMA, just disable
support for SWDMA modes for now.
* Enable support for MWDMA0 mode.

sis5513: DMA setup fixes
* Add sis_ata133_get_base() helper function for obtaining the address of
the drive control registers on chipset_family == ATA_133 chipsets.
* Add three helper functions for programming PIO/MWDMA timings:
- sis_ata16_program_timings() (for ATA_16/33/66/100a chipset families)
- sis_ata100_program_timings() (for ATA_100/133a chipset families)
- sis_ata133_program_timings() (for ATA_133 chipset family)
MWDMA timings are taken from datasheets and they match ATA spec.
* Add generic helper function sis_program_timings() and use it in
->set_pio_mode and ->set_dma_mode methods (previously the driver
depended on BIOS to program the correct MWDMA timings).
* Remove redundant !chipset_family check from init_hwif_sis5513()
(init_chipset_sis5513() guarantees that we will never get here if
chipset_family cannot be determined).
* SWDMA seems to be unsupported by SiS chipsets (no info about SWDMA in
datasheets and for SWDMA0 mode timing requirements are impossible to
fulfill) so remove ->swdma_mask from init_hwif_sis5513() and handling
of SWDMA modes from sis_set_dma_mode().
* Enable DMA support for chipset_family == ATA_16.
* Bump driver version.
