  51c78eb3: x86: create _types.h counterparts for page*.h

Cc: Jeremy Fitzhardinge <jeremy@goop.org>
Signed-off-by: NIngo Molnar <mingo@elte.hu>

Merge branches 'x86/acpi', 'x86/apic', 'x86/cpudetect', 'x86/headers', 'x86/paravirt', 'x86/urgent' and 'x86/xen'; commit 'v2.6.29-rc5' into x86/core

Impact: cleanup

1. move localise_nmi_watchdog() later
2. change setup_boot_APIC_clock() to setup_boot_clock() for 64-bit

Impact: cleanup

set default value early - this allows the removal of a number
of dynamic initialization codepaths, and an #ifdef.

We can't call the callbacks after enabling interrupts, as we may get a

Impact: fix wrong disabling of cpu features

an amd system got this strange output:

 CPU: CPU feature monitor disabled due to lack of CPUID level 0x5

but in /proc/cpuinfo I have:

 cpuid level	: 5

on intel system:

 CPU: CPU feature monitor disabled due to lack of CPUID level 0x5
 CPU: CPU feature dca disabled due to lack of CPUID level 0x9

but in /proc/cpuinfo i have:

 cpuid level     : 11

Tt turns out there is a typo, and we should use level member in df.

Commit e51a1ac2 ("x86, olpc: fix endian

0xc2 needs to be scaled up by olpc_board().

The pre-patch version was wrong, but accidentally worked anyway
(big-endian 0xc2 is big enough to satisfy all other board revisions,
but little endian 0xc2 is not).

uids in namespaces other than init don't get a sysfs entry.

For those in the init namespace, while we're waiting to remove
the sysfs entry for the uid the uid is still hashed, and
alloc_uid() may re-grab that uid without getting a new
reference to the user_ns, which we've already put in free_user
before scheduling remove_user_sysfs_dir().

ASoC supports both explicit codec drivers for AC97 devices and a simple
driver which uses the standard ALSA AC97 framework for codec support.
When used with the generic AC97 codec support that will provide the
ad hoc AC97 device for drivers like touchscreens to attach to so the
core shouldn't do so.

        x86: change flush_tlb_others to take a const struct cpumask

causes xen_flush_tlb_others to allocate a multicall and then issue it
without initializing it in the case where the cpumask is empty,
leading to:

Since empty cpumasks are rare and undoing an xen_mc_entry() is tricky
just issue such requests normally.

Added the helper function snd_hda_multi_out_dig_cleanup() to clean up
the digital outputs with multi setup.  This call is needed in cases
the codec supports multiple digital outputs as slaves.  Otherwise the
slave widgets aren't properly cleaned up.

For a single digital output (e.g. in patch_conexant.c), this call isn't
needed.
