d46557955f [NET]: Relax the reference counting of init_net_ns
When the CONFIG_NET_NS is n there's no need in refcounting
the initial net namespace. So relax this code by making a
stupid stubs for the "n" case.

6257ff2177 [NET]: Forget the zero_it argument of sk_alloc()
Finally, the zero_it argument can be completely removed from
the callers and from the function prototype.

Besides, fix the checkpatch.pl warnings about using the
assignments inside if-s.

This patch is rather big, and it is a part of the previous one.
I splitted it wishing to make the patches more readable. Hope 
this particular split helped.

52eb053b71 [SPARC64]: Fix linkage of enormous kernels.
This was found by make randconfig

If the kernel .text is very large, the .fixup section branches
are too far away to be relocated correctly.

Use "sethi %hi(label), reg; jmpl reg + %lo(label); %g0" sequence
instead of the branch to fix this.

There is another case in switch_to() involving a branch, which
is fixed similarly.

558de8a74e [ARM] 4634/1: DaVinci GPIO header build fix
This fixes a build problem with GPIOs on DaVinci.  Since it inlines
operations for on-chip GPIOs, it needs some headers to support those
direct register accesses.  Those headers won't be included on other
platforms, since they don't have that optimization.

It wants string functions like memcpy() for inline

e027bd36c1 libata: implement and use ATA_QCFLAG_QUIET
Implement ATA_QCFLAG_QUIET which indicates that there's no need to
report if the command fails with AC_ERR_DEV and set it for passthrough
commands.

Combined with previous changes, this now makes device errors for all
direct commands reported directly to the issuer without going through
EH actions and reporting.

Note that EH is still invoked after non-IO device errors to determine
the nature of the error and resume command execution (some controller
requires special care after error to continue).  It just performs
default maintenance after error, examines what's going on, realizes
that it's none of its business and reports the command failure without
logging any error messages.

6a22c57b8d Revert "x86_64: allocate sparsemem memmap above 4G"
This reverts commit 2e1c49db4c.

First off, testing in Fedora has shown it to cause boot failures,
bisected down by Martin Ebourne, and reported by Dave Jobes.  So the
commit will likely be reverted in the 2.6.23 stable kernels.

Secondly, in the 2.6.24 model, x86-64 has now grown support for
SPARSEMEM_VMEMMAP, which disables the relevant code anyway, so while the
bug is not visible any more, it's become invisible due to the code just
being irrelevant and no longer enabled on the only architecture that
this ever affected.

keep utime/stime monotonic.

cpustats use utime/stime as a ratio against sum_exec_runtime, as a

accumulates - that either can be appear to go backwards.

229f773ef4 [MIPS] txx9tmr clockevent/clocksource driver
Convert jmr3927_clock_event_device to more generic
txx9tmr_clock_event_device which supports one-shot mode.  The
txx9tmr_clock_event_device can be used for TX49 too if the cp0 timer
interrupt was not available.

Convert jmr3927_hpt_read to txx9_clocksource driver which does not
depends jiffies anymore.  The txx9_clocksource itself can be used for
TX49, but normally TX49 uses higher precision clocksource_mips.

113134fcbc [IA64] /proc/cpuinfo "physical id" field cleanups
Clean up the process for presenting the "physical id" field in
/proc/cpuinfo.

	- remove global smp_num_cpucores, as it is mostly useless

	- remove check_for_logical_procs(), since we do the same
	  functionality in identify_siblings()

	- reflow logic in identify_siblings(). If an older CPU
	  does not implement PAL_LOGICAL_TO_PHYSICAL, we may still
	  be able to get useful information from SAL_PHYSICAL_ID_INFO

	- in identify_siblings(), threads/cores are a property of
	  the CPU, not the platform

	- remove useless printk's about multi-core / thread
	  capability in identify_siblings(), as that information
	  is readily available in /proc/cpuinfo, and printing for
	  the BSP only adds little value

	- smp_num_siblings is now meaningful if any CPU in the
	  system supports threads, not just the BSP

	- expose "physical id" field, even on CPUs that are not
	  multi-core / multi-threaded (as long as we have a valid
	  value). Now we know what sockets Madisons live in too.

ca77329fb7 [libata] Link power management infrastructure
Device Initiated Power Management, which is defined
in SATA 2.5 can be enabled for disks which support it.
This patch enables DIPM when the user sets the link
power management policy to "min_power".

Additionally, libata drivers can define a function
(enable_pm) that will perform hardware specific actions to
enable whatever power management policy the user set up
for Host Initiated Power management (HIPM).
This power management policy will be activated after all
disks have been enumerated and intialized.  Drivers should
also define disable_pm, which will turn off link power
management, but not change link power management policy.

Documentation/scsi/link_power_management_policy.txt has additional
information.
