* Add cmpxchg64 and cmpxchg64_local to alphaMathieu Desnoyers2008-02-071-2/+13
| | | | | | | | | | | Make sure that at least cmpxchg64_local is available on all architectures to use for unsigned long long values.

* increase AT_VECTOR_SIZE to terminate saved_auxv properlyOlaf Hering2007-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO. fs/binfmt_elf.c has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT entries. So in the worst case, saved_auxv does not get an AT_NULL entry at the end. The saved_auxv array must be terminated with an AT_NULL entry. Make the size of mm_struct->saved_auxv arch dependend, based on the number of ARCH_DLINFO entries.

* [PATCH] __cmpxchg() must really always be inlined on alphaSteve Langasek2006-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | With the latest 2.6.15 kernel builds for alpha on Debian, we ran into a problem with undefined references to __cmpxchg_called_with_bad_pointer() in a couple of kernel modules (xfs.ko and drm.ko; see http://bugs.debian.org/347556). It looks like people have been trying to out-clever each other wrt the definition of "inline" on this architecture :), with the result that __cmpxchg(), which must be inlined so the compiler can see its argument is const, is not guaranteed to be inlined. Indeed, it was not being inlined when building with -Os. The attached patch fixes the issue by adding an __attribute__((always_inline)) explicitly to the definition of __cmpxchg() instead of relying on redefines of "inline" elsewhere to make this happen.

* [PATCH] alpha: atomic dependency fixAndrew Morton2005-10-251-30/+1
| | | | | | | | | | | | | My alpha build is exploding because asm/atomic.h now needs smb_mb(), which is over in the (not included) system.h. I fear what will happen if I include system.h into atomic.h, so let's put the barriers into their own header file.

* [PATCH] alpha xchg fixAl Viro2005-08-231-16/+13
| | | | | | | | | alpha xchg has to be a macro - alpha disables always_inline and if that puppy does not get inlined, we immediately blow up on undefined reference. Happens even on gcc3; with gcc4 that happens a _lot_. Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+626
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!
