Subject[PATCH] fixmap.h WAS: Problems with memo
Date

Hi Linus,
Hi all,

patch 2.1.110 introduce fixmap.h for ix86
For UP, __end_of_fixed_addresses is 0 so
FIXADDR_START aka VMALLOC_END is 0x1000 :-(

For SMP, __end_of_fixed_addresses is 3 so
VMALLOC_END is 0xffffe000,

Following patch reserve the last VM page for UP,
so VMALLOC_END is 0xfffff000
