7bf2368742 [PATCH] swsusp: Do not fail if resume device is not set
In the kernels later than 2.6.19 there is a regression that makes swsusp
fail if the resume device is not explicitly specified.

It can be fixed by adding an additional parameter to
mm/swapfile.c:swap_type_of() allowing us to pass the (struct block_device
*) corresponding to the first available swap back to the caller.

Fix filenames on adfs discs being terminated at the first character greater

6c5f8cc33e [PATCH] atiixp: Old drivers/ide layer driver for the ATIIXP hang fix
When the old IDE layer calls into methods in the driver during error
handling it is essentially random whether ide_lock is already held.  This
causes a deadlock in the atiixp driver which also uses ide_lock internally
for locking.

Switch to a private lock instead.

406c9b605c [PATCH] Fix BUG at drivers/scsi/scsi_lib.c:1118 caused by "pktsetup dvd /dev/sr0"
Fix http://bugzilla.kernel.org/show_bug.cgi?id=7667

This is because the packet driver tries to send down read/write BLOCK_PC
commands that don't use a bio and do not use sg lists.

The right fix is to replace all the packet_command stuff in the packet
driver by scsi_execute() which needs to be lifted from scsi code to
the block code for that.

Fix the bug for now.  It's not the full way to a generic execute block pc
infrastcuture but fixes the bug for the time being.

c1150d8cf9 [PATCH] KVM: Improve interrupt response
The current interrupt injection mechanism might delay an interrupt under
the following circumstances:

 - if injection fails because the guest is not interruptible (rflags.IF clear,
   or after a 'mov ss' or 'sti' instruction).  Userspace can check rflags,
   but the other cases or not testable under the current API.
 - if injection fails because of a fault during delivery.  This probably
   never happens under normal guests.
 - if injection fails due to a physical interrupt causing a vmexit so that
   it can be handled by the host.

In all cases the guest proceeds without processing the interrupt, reducing
the interactive feel and interrupt throughput of the guest.

This patch fixes the situation by allowing userspace to request an exit
when the 'interrupt window' opens, so that it can re-inject the interrupt
at the right time.  Guest interactivity is very visibly improved.

KVM does kmalloc() in an atomic section while having preemption disabled via
vcpu_load().  Fix this by moving the ->*_msr setup from the vcpu_setup method

cd36beec0b [PATCH] via82cxxx: fix cable detection
This patch fixes 2.6.15 regression, is straightforward and tested.

Cable detection got broken probably while converting the driver to support
multiple controllers.  Cable detection is done by examining how BIOS
configured the attached devices.  The current code is broken in that it
examines the status *after* modifying Clk66 configuration ending up
detecting 40c cables as 80c.  This patch fixes it.

6ae4adf503 [PATCH] PCI: prevent down_read when pci_devices is empty
The pci_find_subsys gets called very early by obsolete ide setup parameters.
This is a bogus call since pci is not initialized yet, so the list is empty.
But in the mean time, interrupts get enabled by down_read.  This can result in
a kernel panic when the irq controller gets initialized.

This patch checks if the device list is empty before taking the semaphore, and
hence will not enable irq's.  Furthermore it will inform that it is called
while pci_devices is empty as a reminder that the ide code needs to be fixed.

The pci_get_subsys can get called in the same manner, and as such is patched
in the same manner.

a416aba637 [PATCH] kernelparams: detect if and which parameter parsing enabled irq's
The parsing of some kernel parameters seem to enable irq's at a stage that
irq's are not supposed to be enabled (Particularly the ide kernel parameters).

Having irq's enabled before the irq controller is initialized might lead to a

parameter caused it.

The calls made by parse_parms to other initialization code might enable
interrupts again way too early.

Having interrupts on this early can make systems PANIC when they initialize
the IRQ controllers (which happens later in the code).  This patch detects
that irq's are enabled again, barfs about it and disables them again as a

2e11c207b0 [PATCH] cdrom: set default timeout to 7 seconds
It's a known fact that Windows times out commands after 7 seconds, so
drives generally try and respond if they can before that happens.  We
default to 5 seconds, which sometimes is a bit too short.

Jeremy Higdon reported here:

	http://lkml.org/lkml/2007/1/1/145

that his drive takes longer than 5 seconds for a "read track
information" command, later confirming that it is about 6.7 seconds.

So just do the sane thing and change the default command timeout to 7
seconds to avoid other surprises.

7523c4dd99 [PATCH] x86_64: Fix dump_trace()
If caller passed the tsk, we should use it to validate a stack ptr.
Otherwise, sysrq-t and other debugging stuff doesn't work.

24ebead82b [CPUFREQ] Longhaul - Always guess FSB
This is patch that solves Ebox mini PC issue and make
FSB code more specification compilant. At start guess_fsb
function is guessing 200MHz FSB too. It is better to
make it in this way because, thanks to this function, driver
will fail for bogus FSB values caused by bogus multiplier
value. For PowerSaver processors we can't depend on Max /
MinMHzFSB because these values are only used for
PowerSaver 2.0 and 3.0. Most processors on which Longhaul
is used are PowerSaver 1.0 only. I'm changing code for older
CPU's too, but not so much as previously, and this code was
already used for Ezra. Using MinMHzBR for Ezra-T is outside
spec. It is for voltage scaling purpose and don't have to
be equal to minmult (but it is). Same for Nehemiah (it
isn't for sure). Added mult - current multiplier value.

d02b161eda [ARM] 4081/1: Add definition for TI Sync Serial Protocol
Of the possible SSP frame formats (FRF bits in SSCR0), only SSCR0_PSP is defined. Other possible formats are Motorola SPI (0<<4), TI SSP (1<<4) and Microwire (2<<4). Attached patch adds a definition SSCR0_TISSP.
This mode is used for the sound codec attached to the PXA272 SSP1 of some HTC PDA phones.
