2006-02-09[NETLINK]: Fix a severe bugAlexey Kuznetsov1-1/+2
netlink overrun was broken while improvement of netlink. Destination socket is used in the place where it was meant to be source socket, so that now overrun is never sent to user netlink sockets, when it should be, and it even can be set on kernel socket, which results in complete deadlock of rtnetlink. Suggested fix is to restore status quo passing source socket as additional argument to netlink_attachskb(). A little explanation: overrun is set on a socket, when it failed to receive some message and sender of this messages does not or even have no way to handle this error. This happens in two cases: 1. when kernel sends something. Kernel never retransmits and cannot wait for buffer space. 2. when user sends a broadcast and the message was not delivered to some recipients.

Patch from Tony Lindgren This patch adds the missing cache flushes to common low-level init that are needed to access the IO region. These flushes are normally done at the end of devicemaps_init(), but we need to detect the OMAP core type early.

2006-02-08[ARM] 3311/1: clean up include/asm-arm/mutex.hNicolas Pitre1-66/+65
Patch from Nicolas Pitre Since: if (unlikely(__res || __ex_flag)) produces worse code on ARM than: if (unlikely(__res | __ex_flag)) I therefore made it more explicit: __res |= __ex_flag; if (unlikely(__res != 0)) so it is not seen as a typo again. Also made everything static inline rather than macros for better readability (both produce the same code after all). And finally added missing \t from multi-line assembly code.

2006-02-08[PATCH] block: implement elv_insert and use it (fix ordcolor flipping bug)Tejun Heo1-0/+1
q->ordcolor must only be flipped on initial queueing of a hardbarrier request. Constructing ordered sequence and requeueing used to pass through __elv_add_request() which flips q->ordcolor when it sees a barrier request. This patch separates out elv_insert() from __elv_add_request() and uses elv_insert() when constructing ordered sequence and requeueing. elv_insert() inserts the given request at the specified position and does nothing else.

2006-02-07[PATCH] powerpc: Thermal control for dual core G5sBenjamin Herrenschmidt1-0/+5
This patch adds a windfarm module, windfarm_pm112, for the dual core G5s (both 2 and 4 core models), keeping the machine from getting into vacuum-cleaner mode ;) For proper credits, the patch was initially written by Paul Mackerras, and slightly reworked by me to add overtemp handling among others. The patch also removes the sysfs attributes from windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm core to automagically expose attributes for sensor & controls.

2006-02-07[PATCH] mm: compound release fixNick Piggin1-1/+1
Compound pages on SMP systems can now often be freed from pagetables via the release_pages path. This uses put_page_testzero which does not handle compound pages at all. Releasing constituent pages from process mappings decrements their count to a large negative number and leaks the reference at the head page - net result is a memory leak. The problem was hidden because the debug check in put_page_testzero itself actually did take compound pages into consideration. Fix the bug and the debug check.

2006-02-07[PATCH] __cmpxchg() must really always be inlined on alphaSteve Langasek1-1/+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.

2006-02-07[PATCH] x86_64: Fix the node cpumask of a cpu going downRavikiran G Thirumalai1-0/+7
Currently, x86_64 and ia64 arches do not clear the corresponding bits in the node's cpumask when a cpu goes down or cpu bring up is cancelled. This is buggy since there are pieces of common code where the cpumask is checked in the cpu down code path to decide on things (like in the slab down path). PPC does the right thing, but x86_64 and ia64 don't (This was the reason Sonny hit upon a slab bug during cpu offline on ppc and could not reproduce on other arches). This patch fixes it for x86_64. I won't attempt ia64 as I cannot test it. Credit for spotting this should go to Alok. (akpm: this was applied, then reverted. But it's OK now because we now use for_each_cpu() in the right places).

2006-02-07[MIPS] TX49x7: Fix reporting of the CPU name and PCI clockSergei Shtylylov1-0/+10
I've noticed that PCI clock was incorrectly reported as 66 MHz while being mere 33 MHz on RBTX4937 board -- this was due to the different encoding of the PCI divisor field in CCFG register between TX4927 and TX4937 chips... Also, RBTX49x7 was printed out as a CPU name (e.g., "CPU is RBTX4937"); and some debug printk() were duplicating each other...

ERT-TX49H2-027, ERT-TX49H3-012, ERT-TX49HL3-006, ERT-TX49H4-008 Workaround: mask EXL bit of the result or place a nop before mfc0.
