MIPS: Limit fixrange_init() to the FIXMAP region

2011-07-25T16:26:54+00:00

fixrange_init() allocates page tables for all addresses higher than FIXADDR_TOP. On processors that override the default FIXADDR_TOP address of 0xfffe_0000, this can consume up to 4 pages (1 page per 4MB) for pgd's that are never used.

[MIPS] Add external declaration of pagetable_init() to pgalloc.h

2007-02-18T21:31:36+00:00

This fixes some sparse warnings. pgtable-32.c:15:6: warning: symbol 'pgd_init' was not declared. Should it be static? pgtable-32.c:32:13: warning: symbol 'pagetable_init' was not declared. Should it be static? Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_page

2006-10-21T22:17:35+00:00

The current implementation uses a sequence of a cacheflush and a copy. This is racy in case of a multithreaded debuggee and renders GDB virtually unusable. Aside this fixes a performance hog rendering access to /proc/cmdline very slow and resulting in a enough cache stalls for the 34K AP/SP programming model to make the bare metal code on the non-Linux VPE miss RT deadlines. The main part of this patch was originally written by Ralf Baechle; Atushi Nemoto did the the debugging. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
