2005-11-13[PATCH] uml: fix access_okPaolo 'Blaisorblade' Giarrusso
The access_ok_tt() macro is bogus, in that a read access is unconditionally considered valid. I couldn't find in SCM logs the introduction of this check, but I went back to 2.4.20-1um and the definition was the same. Possibly this was done to avoid problems with missing set_fs() calls, but there can't be any I think because they would fail with SKAS mode. TT-specific code is still to check. Also, this patch joins common code together, and makes the "address range wrapping" check happen for all cases, rather than for only some. This may, possibly, be reoptimized at some time, but the current code doesn't seem clever, just confused. * Important: I've also had to change references to access_ok_{tt,skas} back to access_ok - the kernel wasn't that happy otherwise.

2005-05-06[PATCH] uml: x86_64 fixesJeff Dike
This fixes some x86_64 bugs - - maybe_map returns -1 on error instead of 0, which is interpreted as physical address 0 - removed an include of ipc.h, which isn't needed - fixed the calculation of signal frame location - the signal delivery code is now immune to the stack expansion check - added a missing include Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-01[PATCH] uml: move va_copy conditional defPaolo 'Blaisorblade' Giarrusso
GCC 2.95 uses __va_copy instead of va_copy. Handle it inside compiler.h instead of in a casual file, and avoid the risk that this breaks with a newer compiler (which it could do).

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!
