[PATCH] __cmpxchg() must really always be inlined on alpha

2006-02-08T00:12:31Z

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: task_thread_info()

[PATCH] sched: add cacheflush() asm

2006-01-12T17:08:49Z

Add per-arch sched_cacheflush() which is a write-back cacheflush used by the migration-cost calibration code at bootup time. Signed-off-by: Ingo Molnar Cc: Nick Piggin Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] alpha: atomic dependency fix

2005-10-25T16:32:46Z

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 fix

2005-08-24T01:43:44Z

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 Signed-off-by: Linus Torvalds

Linux-2.6.12-rc2

2005-04-16T22:20:36Z

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!
