*	x86/mm: Move pgprot2cachemode out of line	Christoph Hellwig	2020-04-20	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \|	This helper is only used by x86 low-level MM code. Also remove the entirely pointless __pte2cachemode_tbl export as that symbol can be marked static now.

*	x86/mm: Add a x86_has_pat_wp() helper	Christoph Hellwig	2020-04-20	1	-0/+2
\| \| \| \| \| \| \| \| \|	Abstract the ioremap code away from the caching mode internals.

*	x86/mm/pat: Clean up <asm/memtype.h> externs	Ingo Molnar	2019-12-10	1	-5/+5
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Half of the declarations have an 'extern', half of them not, use 'extern' consistently. This makes grepping for APIs easier, such as: dagon:~/tip> git grep -E '\<memtype_.\(' arch/x86/ \| grep extern arch/x86/include/asm/memtype.h:extern int memtype_reserve(u64 start, u64 end, arch/x86/include/asm/memtype.h:extern int memtype_free(u64 start, u64 end); arch/x86/include/asm/memtype.h:extern int memtype_kernel_map_sync(u64 base, unsigned long size, arch/x86/include/asm/memtype.h:extern int memtype_reserve_io(resource_size_t start, resource_size_t end, arch/x86/include/asm/memtype.h:extern void memtype_free_io(resource_size_t start, resource_size_t end); arch/x86/mm/pat/memtype.h:extern int memtype_check_insert(struct memtype entry_new, arch/x86/mm/pat/memtype.h:extern struct memtype memtype_erase(u64 start, u64 end); arch/x86/mm/pat/memtype.h:extern struct memtype memtype_lookup(u64 addr); arch/x86/mm/pat/memtype.h:extern int memtype_copy_nth_element(struct memtype *entry_out, loff_t pos); Signed-off-by: Ingo Molnar <mingo@kernel.org>
*	x86/mm/pat: Rename <asm/pat.h> => <asm/memtype.h>	Ingo Molnar	2019-12-10	1	-0/+27
	pat.h is a file whose main purpose is to provide the memtype_*() APIs. PAT is the low level hardware mechanism - but the high level abstraction is memtype. So name the header <memtype.h> as well - this goes hand in hand with memtype.c and memtype_interval.c. Signed-off-by: Ingo Molnar <mingo@kernel.org>
