[Bluetooth] Change inquiry_cache to hci_inquiry_cache
This patch changes the inquiry_* functions to be either local to hci_core.c
or change name from inquiry_cache_lookup to hci_inquiry_cache_lookup to try
and reduce the potential for namespace conflicts. There could be USB or SCSI
or other code that uses an inquiry_cache.

[Bluetooth] Fix config change for firmware loading
The switching between firmware loading and running state is done via
different configurations. To get this right the USB toggle and halted

This patch fixes the problem that ACL connections are removed from

command status other than 0x00.

[PATCH] insert_resource fix

existing parent resource with the same ending address as a newly added

PIO handlers under CONFIG_IDE_TASKFILE_IO=n are never used for bio
based requests (rq->bio is always NULL) so we can use rq->buffer
directly instead of calling ide_[un]map_buffer().
[PATCH] ide: cleanup taskfile PIO handlers (CONFIG_IDE_TASKFILE_IO=n)
These handlers are nowadays used only for REQ_DRIVE_TASKFILE
requests (rq->bio is always NULL) which aren't retried et all so
remove code 'rewinding' rq->current_nr_sectors and some FIXMEs.
[PATCH] ide: fix ide-cd to not retry REQ_DRIVE_TASKFILE requests
'cat /proc/ide/hdx/identify' generates REQ_DRIVE_TASKFILE request
(for WIN_PIDENTIFY command) even for devices controlled by ide-cd.
All other drivers don't try to retry such requests.
- do not unregister ide-pnp driver while detaching random
IDE device from random IDE device driver if IDE is modular
(somebody added this in 2.3.51)
- clear 'hw_regs_t hw' allocated from stack
- mark idepnp_init() with __init
- use ide_std_init_ports() instead of ide_setup_ports()
The IDE sparse fixups cause 2 warnings (unused variables `val' and
`reg') on m68k and APUS. However, the reason why this code was
commented out is gone. So just remove the special case.

[NETFILTER]: Don't assign new helper after NAT when there are already expectations present.
Tracked down by Raivis Bucis <raivis@mt.lv>
This patch fixes an oops while listing /proc/net/ip_conntrack.
When a helper sets up expectations based on the first packet (tftp),
NAT can still change the packet and cause conntrack to look for a new helper
based on the new tuple. When no helper is found, expectant->helper will be
NULL, which leads to an oops in print_expect().
Only assign a new helper in ip_conntrack_alter_reply() if there are no
expectations.

[PATCH] Fix nfs writepage behaviour
From: Nick Piggin <nickpiggin@yahoo.com.au>
nfs_writepage() refuses to write back mapped pages at all on the page
reclaim path, causing systems to get locked up when there's a lot of dirty
mmapped data around. The patch changes NFS so that it will start I/O
against these pages.
The code as it stands is designed to defer writeout to pdflush which can do
larger, more efficient I/Os. But there shouldn't be much traffic by this
path, and going slow is better than not going at all.

[PATCH] Fix x86-64 VIA systems with IOMMU debug
VIA chipsets are broken and don't work with IOMMU enabled. For some mysterious
reason (the IOMMU logic is actually in the CPU) they manage to corrupt all
data going through the aperture to PCI devices.
There was a workaround previously that enabled the slower softmmu when VIA is
detected on the normal IOMMU path (when there is more than 3GB of memory). But
CONFIG_IOMMU_DEBUG took a short cut that was not handled, which ended up with
VIA systems not booting when this option is enabled.
This patch enables the workaround with CONFIG_IOMMU_DEBUG/iommu=force too

[PATCH] ia64: fix race in fsys_bubble_down to avoid fp-register corruption
The fast system-call fall-back-path has a race: it reads PSR, modifies
some bits, then writes back the new PSR. Unfortunately, the contents
of PSR may change between reading and writing it. For example, an
interrupt could occur which could trigger a context-switch. The
context-switch might in turn flush the floating-point-high (FPH)
partition to memory, clear PSR.MFH, and set PSR.DFH. To prevent this
race, the patch below turns off PSR.I before reading PSR.
This fixes a floating-point corruption problem that was observed on a
system with a libc which has the fast system-call support enabled.
The performance impact is minimal (on the order of a handful of cycles).
