Ingo Molnar	b6fd6f2673	x86, mm: limit MAXMEM on 64-bit ... on 64-bit x86 the physical memory limit is controlled by the sparsemem bits - which are 44 bits right now. But MAXMEM (the max pfn number e820 parsing will allow to enter our sizing routines) is set to 0x00003fffffffffff, i.e. 46 bits - that's too large because it overlaps into the vmalloc range. So couple MAXMEM to MAX_PHYSMEM_BITS, and add a comment that the maximum of MAX_PHYSMEM_BITS is 45 bits. Signed-off-by: Ingo Molnar <mingo@elte.hu>	2008-12-16 19:31:52 +01:00
H. Peter Anvin	1965aae3c9	x86: Fix ASM_X86__ header guards ... Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H.
