2007-03-17[MIPS] Lockdep: Fix recursion bug.Ralf Baechle1-8/+8
trace_hardirqs_off -> atomic_inc -> local_irq_restore -> trace_hardirqs_off Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-02-13[MIPS] Improve branch prediction in ll/sc atomic operations.Ralf Baechle1-4/+16
Now that finally all supported versions of binutils have functioning support for .subsection use .subsection to tweak the branch prediction I did not modify the R10000 errata variants because it seems unclear if this will invalidate the workaround which actually relies on the cheesy prediction of branch likely to cause a misspredict if the sc was successful.

2006-12-10[MIPS] Move die and die_if_kernel() from system.h to ptrace.hRalf Baechle1-9/+0
This eleminates the need to include ptrace.h into system.h and fixes a harmless namespace conflict on the PC symbol in bpck.c. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Also the R4000 / R4600 LL/SC instructions imply a sync so no explicit sync needed. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-07-14[PATCH] remove set_wmb - arch removalSteven Rostedt1-3/+0
set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway. Hasn't been tested on any archs but x86 and x86_64 (and only compiled tested) Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-25[PATCH] sched: cleanup context switch lockingNick Piggin1-8/+2
Instead of requiring architecture code to interact with the scheduler's locking implementation, provide a couple of defines that can be used by the architecture to request runqueue unlocked context switches, and ask for interrupts to be enabled over the context switch. Also replaces the "switch_lock" used by these architectures with an oncpu flag (note, not a potentially slow bitflag). This eliminates one bus locked memory operation when context switching, and simplifies the task_running function.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+438
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!
