The as-instr/ld-option need to create temporary files, but create them in the
output directory, when compiling external modules. Reformat them a bit and
use $(CC) instead of $(AS) as the former is used by kbuild to assemble files.

libata waits for !BSY even when the status register reports 0xff.
This causes long boot delays when D8 isn't pulled down properly. This
patch does the followings.
* don't wait if status register is 0xff in all wait functions
* make ata_busy_sleep() return 0 on success and -errno on failure.
-ENODEV is returned on 0xff status and -EBUSY on other failures.
* make ata_bus_softreset() succeed on 0xff status. 0xff status is not
reset failure. It indicates no device. This removes unnecessary
retries on such ports. Note that the code change assumes unoccupied
port reporting 0xff status does not produce valid device signature.

The TUNER_LG_NTSC_TAPE is identical in all respects to the
TUNER_PHILIPS_FM1236_MK3. So use the params struct for the Philips tuner.
Also add this LG_NTSC_TAPE tuner to the switches where radio specific
parameters are set so it behaves like a TUNER_PHILIPS_FM1236_MK3. This
change fixes the radio support for this tuner (the wrong bandswitch byte
was used).

In some cases when using VSB, the AGC status register has been known to
falsely report "no signal" when in fact there is a carrier lock. The
datasheet labels these status flags as QAM only, yet the lgdt330x
module is using these flags for both QAM and VSB.
This patch allows for the carrier recovery lock status register to be
tested, even if the agc signal status register falsely reports no signal.

On the Core2 cpus, the rdtsc instruction is not serializing (as defined
in the architecture reference since rdtsc exists) and due to the deep
speculation of these cores, it's possible that you can observe time go
backwards between cores due to this speculation. Since the kernel
already deals with this with the SYNC_RDTSC flag, the solution is
simple, only assume that the instruction is serializing on family 15...
The price one pays for this is a slightly slower gettimeofday (by a
dozen or two cycles), but that increase is quite small to pay for a
really-going-forward tsc counter.

Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel
bugzilla 7645. Right: read_zero_pagealigned uses down_read of mmap_sem,
but another thread's racing read of /dev/zero, or a normal fault, can
easily set that pte again, in between zap_page_range and zeromap_page_range
getting there. It's been wrong ever since 2.4.3.
The simple fix is to use down_write instead, but that would serialize reads
of /dev/zero more than at present: perhaps some app would be badly
affected. So instead let zeromap_page_range return the error instead of
BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in
that case - there's no need to optimize for it.
Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of
zeromap_page_range), though it really isn't interesting there. And since
mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that
than -ENOMEM.

At least some nforce cards continue to send legacy interrupts when MSI
is enabled, and these interrupts are treated as unhandled by the
kernel. This patch disables legacy interrupts explicitly when enabling
MSI mode.
The correct fix is to change the MSI infrastructure to disable legacy
interrupts when enabling MSI, but this is potentially risky if the
device isn't PCI-2.3 or is quirky, so the correct fix is going into
mainline, while patches like this one go into -stable.
Legend has it that it is most correct to disable legacy interrupts
before enabling MSI, but the mainline patch does it in the other
order, and this patch is "obviously" the same as mainline.

2.6.19 stopped booting (or booted based on build/config) on our x86_64
systems due to a bug introduced in 2.6.19. check_nmi_watchdog schedules an
IPI on all cpus to busy wait on a flag, but fails to set the busywait
flag if NMI functionality is disabled. This causes the secondary cpus
to spin in an endless loop, causing the kernel bootup to hang.
Depending upon the build, the busywait flag got overwritten (stack variable)
and caused the kernel to bootup on certain builds. Following patch fixes
the bug by setting the busywait flag before returning from check_nmi_watchdog.
I guess using a stack variable is not good here as the calling function could
potentially return while the busy wait loop is still spinning on the flag.
AK: I redid the patch significantly to be cleaner

The m32r kernel 2.6.18-rc1 or after cause build errors of "unknown isa

It is possible to have tasklets get scheduled before softirqd has had a chance
to spawn on all CPUs. This is totally harmless; after success during action
CPU_UP_PREPARE, action CPU_ONLINE will be called, which immediately wakes
softirqd on the appropriate CPU to process the already pending tasklets. So
there is no danger of having a missed wakeup for any tasklets that were
already pending.
In particular, i386 is affected by this during startup, and is visible when
using a very large initrd; during the time it takes for the initrd to be
decompressed, a timer IRQ can come in and schedule RCU callbacks. It is also
possible that resending of a hardware IRQ via a softirq triggers the same bug.
Because of different timing conditions, this shows up in all emulators and
virtual machines tested, including Xen, VMware, Virtual PC, and Qemu. It is
also possible to trigger on native hardware with a large enough initrd,
although I don't have a reliable case demonstrating that.

When kernel is compiled with old version of autofs (CONFIG_AUTOFS_FS), and

then screws things up instead of correct handling of the error:

and then deadlock comes.
The problem: autofs_fill_super() returns EINVAL to get_sb_nodev(), but
before that, it calls kill_anon_super() to destroy the superblock which
won't be needed. This is however way too soon to call kill_anon_super(),
because get_sb_nodev() has to perform its own cleanup of the superblock
first (deactivate_super(), etc.). The correct time to call
kill_anon_super() is in the autofs_kill_sb() callback, which is called by
deactivate_super() at proper time, when the superblock is ready to be
killed.
I can see the same faulty codepath also in autofs4. This patch solves
issues in both filesystems in a same way - it postpones the
kill_anon_super() until the proper time is signalized by deactivate_super()
calling the kill_sb() callback.

Currently the behaviour of disable_xfrm is inconsistent between
locally generated and forwarded packets. For locally generated
packets disable_xfrm disables the policy lookup if it is set on
the output device, for forwarded traffic however it looks at the
input device. This makes it impossible to disable xfrm on all
devices but a dummy device and use normal routing to direct
traffic to that device.
Always use the output device when checking disable_xfrm.

Commit 590bdf7fd2292b47c428111cb1360e312eff207e introduced a regression
in match/target hook validation. mark_source_chains builds a bitmask
for each rule representing the hooks it can be reached from, which is
then used by the matches and targets to make sure they are only called
from valid hooks. The patch moved the match/target specific validation
before the mark_source_chains call, at which point the mask is always zero.
This patch returns back to the old order and moves the standard checks
to mark_source_chains. This allows to get rid of a special case for
standard targets as a nice side-effect.

This reverts commit 281ea49b0c294649a6de47a6f8fbe5611137726b,
which broke ACPI Interrupt source overrides that move
the SCI from one IRQ in PIC mode to another in IOAPIC mode.
If the SCI shared an interrupt line with another device,
this would result in a "irq 18: nobody cared" type failure.

As CBC is the default chaining method for cryptoloop, we should select
it from cryptoloop to ease the transition.

The tc actions increased the size of struct tc_police, which broke
compatibility with old iproute binaries since both the act_police
and the old NET_CLS_POLICE code check for an exact size match.
Since the new members are not even used, the simple fix is to also
accept the size of the old structure. Dumping is not affected since
old userspace will receive a bigger structure, which is handled fine.

No need to revisit a chain we'd already finished with during
the check for current hook. It's either instant loop (which
we'd just detected) or a duplicate work.

In the scan section of ieee80211softmac, network transmits are disabled.
When SoftMAC re-enables transmits, it may override the wishes of a driver
that may have very good reasons for disabling transmits. At least one failure
in bcm43xx can be traced to this problem. In addition, several unexplained
problems may arise from the unexpected enabling of transmits.

This changes the type of variable "i" in rtl8169_init_one()
from "unsigned int" to "int". "i" is checked for < 0 later,
which can never happen for "unsigned". This results in broken
error handling.

multiple platforms
Move declaration of struct pxa2xx_udc_mach_info from
include/asm-arm/arch-pxa/udc.h to new file
include/asm-arm/mach/udc_pxa2xx.h.
This allow us to use this structure with
multiple platforms - pxa and ixp4xx. USB
device controller used in pxa25x is the same
as controller used in ixp4xx.
