Ralf Baechle	f8829caee3	[MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_page ... 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.

Atsushi Nemoto	f7a849153b	[MIPS] Fix FIXADDR_TOP for TX39/TX49. ... FIXADDR_TOP is used for HIGHMEM and for upper limit of vmalloc area on 32bit kernel. TX39XX and TX49XX have "reserved" segment in CKSEG3 area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX are reserved (unmapped, uncached) therefore can not be used as mapped area.

Linus Torvalds	1da177e4c3	Linux-2.6.12-rc2 ... 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!	20 years ago
