Merge branch 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 mm changes from Ingo Molnar: "The main changes in this cycle were: - reduce the x86/32 PAE per task PGD allocation overhead from 4K to 0.032k (Fenghua Yu) - early_ioremap/memunmap() usage cleanups (Juergen Gross) - gbpages support cleanups (Luis R Rodriguez) - improve AMD Bulldozer (family 0x15) ASLR I$ aliasing workaround to increase randomization by 3 bits (per bootup) (Hector Marco-Gisbert) - misc fixlets" * 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm: Improve AMD Bulldozer ASLR workaround x86/mm/pat: Initialize __cachemode2pte_tbl[] and __pte2cachemode_tbl[] in a bit more readable fashion init.h: Clean up the __setup()/early_param() macros x86/mm: Simplify probe_page_size_mask() x86/mm: Further simplify 1 GB kernel linear mappings handling x86/mm: Use early_param_on_off() for direct_gbpages init.h: Add early_param_on_off() x86/mm: Simplify enabling direct_gbpages x86/mm: Use IS_ENABLED() for direct_gbpages x86/mm: Unexport set_memory_ro() and set_memory_rw() x86/mm, efi: Use early_ioremap() in arch/x86/platform/efi/efi-bgrt.c x86/mm: Use early_memunmap() instead of early_iounmap() x86/mm/pat: Ensure different messages in STRICT_DEVMEM and PAT cases x86/mm: Reduce PAE-mode per task pgd allocation overhead from 4K to 32 bytes
