Merge branch 'x86-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'x86-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (29 commits) xen: unitialised return value in xenbus_write_transaction x86: fix section mismatch warning x86: unmask CPUID levels on Intel CPUs, fix x86: work around PAGE_KERNEL_WC not getting WC in iomap_atomic_prot_pfn. x86: use standard PIT frequency xen: handle highmem pages correctly when shrinking a domain x86, mm: fix pte_free() xen: actually release memory when shrinking domain x86: unmask CPUID levels on Intel CPUs x86: add MSR_IA32_MISC_ENABLE bits to <asm/msr-index.h> x86: fix PTE corruption issue while mapping RAM using /dev/mem x86: mtrr fix debug boot parameter x86: fix page attribute corruption with cpa() Revert "x86: signal: change type of paramter for sys_rt_sigreturn()" x86: use early clobbers in usercopy*.c x86: remove kernel_physical_mapping_init() from init section fix: crash: IP: __bitmap_intersects+0x48/0x73 cpufreq: use work_on_cpu in acpi-cpufreq.c for drv_read and drv_write work_on_cpu: Use our own workqueue. work_on_cpu: don't try to get_online_cpus() in work_on_cpu. ...
