* [PATCH] kprobes: fix unloading of self probed moduleKeshavamurthy Anil S2006-01-11
| | | | | | | | | | | | | | | | | | When a kprobes modules is written in such a way that probes are inserted on itself, then unload of that moudle was not possible due to reference couning on the same module. The below patch makes a check and incrementes the module refcount only if it is not a self probed module. We need to allow modules to probe themself for kprobes performance measurements This patch has been tested on several x86_64, ppc64 and IA64 architectures.

* [PATCH] reiserfs: fix assertion failure in reiserfs+journaled quotasJan Kara2006-01-11
| | | | | | | | | | | | | | | | Sometimes we call do_journal_end() with t_refcount == 0. If quota is turned on and we happen to have some inode with preallocation bad things happen as we try to use the current handle for quota operations. Checks for t_refcount in journal_begin() fail and we Oops. We raise t_refcount to make those checks happy. We should not cause any bad as all the needed quota blocks should be already attached to the transaction (they were attached to the transaction when we allocated those preallocation blocks).

| | | | | | | | | | | | | o fs/proc/vmcore.c compilation gives warnings on ppc64.

* [PATCH] uml: fix missing KBUILD_BASENAMEJeff Dike2006-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.15-mm1 caused kernel-offsets.c to stop compiling with a syntax error in a header. The problem was with KBUILD_BASENAME, which didn't get a definition with the by-hand compilation in the main UML Makefile. This was OK before since the expansion was syntactically the same as the KBUILD_BASENAME token. With -mm1, the expansion is now a quote-delimited string, so there needs to be a definition of it. Since kernel-offsets.c is basically the same as other arches' asm-offsets.c, and those seem to build OK, this patch turns kernel-offsets.c into asm-offsets.c. kernel-offsets.c is in arch/um/sys-$(SUBARCH), i.e. sys-i386 and sys-x86_64, while kbuild expects it to be in arch/um/kernel. kernel-offsets.c is moved to arch/um/include/sysdep-$(SUBARCH)/kernel-offsets.h, which is included by arch/um/kernel/asm-offsets.c. With that, include/asm-um/asm-offsets.h is generated automatically. kernel-offsets.h continues to exist because it needs to be accessible to userspace UML code, and include/asm-um isn't. So, a symlink is made from arch/um/include/kernel-offsets.h to include/asm-um/asm-offsets.h.

One reason for the large number of loads is that we have to synthesize 2 64bit constants (per_cpu__variable_name and __per_cpu_offset). By putting __per_cpu_offset into the paca we can avoid the 2 loads associated with it: ld 11,56(13) /* paca->data_offset */ ld 9,.LC59-.LCTOC1(30) /* per_cpu__variable_name */ ldx 0,9,11 /* load per cpu data Longer term we can should be able to do even better than 3 loads. If per_cpu__variable_name wasnt a 64bit constant and paca->data_offset was in a register we could cut it down to one load. A suggestion from Rusty is to use gcc's __thread extension here. In order to do this we would need to free up r13 (the __thread register and where the paca currently is). So far Ive had a few unsuccessful attempts at doing that :) The patch also allocates per cpu memory node local on NUMA machines. This patch from Rusty has been sitting in my queue _forever_ but stalled when I hit the compiler bug. Sorry about that. Finally I also only allocate per cpu data for possible cpus, which comes straight out of the x86-64 port. On a pseries kernel (with NR_CPUS == 128) and 4 possible cpus we see some nice gains: total used free shared buffers cached Mem: 4012228 212860 3799368 0 0 162424 total used free shared buffers cached Mem: 4016200 212984 3803216 0 0 162424 A saving of 3.75MB. Quite nice for smaller machines. Note: we now have to be careful of per cpu users that touch data for !possible cpus. At this stage it might be worth making the NUMA and possible cpu optimisations generic, but per cpu init is done so early we have to be careful that all architectures have their possible map setup correctly.
