Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Tue, 17 Mar 2009 11:46:01 -0700 x86-32: remove ALLOCATOR_SLOP from head_32.S Impact: cleanup ALLOCATOR_SLOP is a vestigial remain from when we used the bootmem allocator to allocate the kernel's linear memory mapping. Now we directly reserve pages from the e820 mapping, and no longer require secondary structures to keep track of allocated pages.
