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: x86: Fix kprobes build with non-gawk awk x86: Split swiotlb initialization into two stages x86: Regex support and known-movable symbols for relocs, fix _end x86, msr: Remove incorrect, duplicated code in the MSR driver x86: Merge kernel_thread() x86: Sync 32/64-bit kernel_thread x86, 32-bit: Use same regs as 64-bit for kernel_thread_helper x86, 64-bit: Use user_mode() to determine new stack pointer in copy_thread() x86, 64-bit: Move kernel_thread to C x86-64, paravirt: Call set_iopl_mask() on 64 bits x86-32: Avoid pipeline serialization in PTREGSCALL1 and 2 x86: Merge sys_clone x86, 32-bit: Convert sys_vm86 & sys_vm86old x86: Merge sys_sigaltstack x86: Merge sys_execve x86: Merge sys_iopl x86-32: Add new pt_regs stubs cpumask: Use modern cpumask style in arch/x86/kernel/cpu/mcheck/mce-inject.c
