* x86-64: finish cleanup_highmaps()'s job wrt. _brk_endJan Beulich2009-05-08
| | | | | | | | | | | | | | With the introduction of the .brk section, special care must be taken that no unused page table entries remain if _brk_end and _end are separated by a 2M page boundary. cleanup_highmap() runs very early and hence cannot take care of that, hence potential entries needing to be removed past _brk_end must be cleared once the brk allocator has done its job. [ Impact: avoids undesirable TLB aliases ] Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* x86: fix up some bad global variable names in mm/init.cPekka Enberg2009-03-05
| | | | | | | | | | | | Impact: cleanup The table_start, table_end, and table_top are too generic for global namespace so rename them to be more specific.
