2012-01-17x86/UV2: Add accounting for BAU strong nacksCliff Wickman
This patch adds separate accounting of UV2 message "strong nack's" in the BAU statistics. Signed-off-by: Cliff Wickman <cpw@sgi.com> Link: http://lkml.kernel.org/r/20120116212238.GF5767@sgi.com Signed-off-by: Ingo Molnar <mingo@elte.hu>
2012-01-17x86/UV2: Ack BAU interrupt earlierCliff Wickman
This patch moves the ack of the BAU interrupt to the beginning of the interrupt handler so that there is less possibility of a lost interrupt and slower response to a shootdown message.

2012-01-17x86/UV2: Remove stale no-resources test for UV2 BAUCliff Wickman
This patch removes an unnecessary test for a no-destination-resources-available condition that looks like a destination timeout in UV1, but is separately distinguishable in UV2.

2012-01-17x86/UV2: Work around BAU bugCliff Wickman
This patch implements a workaround for a UV2 hardware bug. The bug is a non-atomic update of a memory-mapped register. When hardware message delivery and software message acknowledge occur simultaneously the pending message acknowledge for the arriving message may be lost. This causes the sender's message status to stay busy. Part of the workaround is to not acknowledge a completed message until it is verified that no other message is actually using the resource that is mistakenly recorded in the completed message. Part of the workaround is to test for long elapsed time in such a busy condition, then handle it by using a spare sending descriptor. The stay-busy condition is eventually timed out by hardware, and then the original sending descriptor can be re-used. Most of that logic change is in keeping track of the current descriptor and the state of the spares. The occurrences of the workaround are added to the BAU statistics.

2012-01-17x86/UV2: Fix BAU destination timeout initializationCliff Wickman

2012-01-17x86/UV2: Fix new UV2 hardware by using native UV2 broadcast modeCliff Wickman
Update the use of the Broadcast Assist Unit on SGI Altix UV2 to the use of native UV2 mode on new hardware (not the legacy mode). UV2 native mode has a different format for a broadcast message. We also need quick differentiaton between UV1 and UV2.

When suspending, there was a large list of warnings going something like: Device 'machinecheck1' does not have a release() function, it is broken and must be fixed This patch turns the static mce_devices into dynamically allocated, and properly frees them when they are removed from the system.

2012-01-15Kbuild: Use dtc's -d (dependency) optionStephen Warren
This hooks dtc into Kbuild's dependency system. Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous lack of this feature recently caused me to have very confusing "git bisect" results. For ARM, it's obvious what to add to $(targets). I'm not familiar enough with other architectures to know what to add there. Powerpc appears to already add various .dtb files into $(targets), but the other archs may need something added to $(targets) to work.

2012-01-13x86/mce: Fix CPU hotplug and suspend regression related to MCESrivatsa S. Bhat
Commit 8a25a2fd126c ("cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystem") changed how things are dealt with in the MCE subsystem. Some of the things that got broken due to this are CPU hotplug and suspend/hibernate. MCE uses per_cpu allocations of struct device. So, when a CPU goes offline and comes back online, in order to ensure that we start from a clean slate with respect to the MCE subsystem, zero out the entire per_cpu device structure to 0 before using it.

2012-01-13ARM: Add arm_memblock_steal() to allocate memory away from the kernelRussell King
Several platforms are now using the memblock_alloc+memblock_free+ memblock_remove trick to obtain memory which won't be mapped in the kernel's page tables. Most platforms do this (correctly) in the ->reserve callback. However, OMAP has started to call these functions outside of this callback, and this is extremely unsafe - memory will not be unmapped, and could well be given out after memblock is no longer responsible for its management. So, provide arm_memblock_steal() to perform this function, and ensure that it panic()s if it is used inappropriately. Convert everyone over, including OMAP. As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot with this change. Mark this option as BROKEN and make it depend on BROKEN. OMAP needs to be fixed, or 137d105d50 (ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.) reverted until such time it can be fixed correctly.

2012-01-12Merge branch 'akpm' (aka "Andrew's patch-bomb, take two")Linus Torvalds
Andrew explains: - various misc stuff - Most of the rest of MM: memcg, threaded hugepages, others. - cpumask - kexec - kdump - some direct-io performance tweaking - radix-tree optimisations - new selftests code A note on this: often people will develop a new userspace-visible feature and will develop userspace code to exercise/test that feature. Then they merge the patch and the selftest code dies. Sometimes we paste it into the changelog. Sometimes the code gets thrown into Documentation/(!). This saddens me. So this patch creates a bare-bones framework which will henceforth allow me to ask people to include their test apps in the kernel tree so we can keep them alive. Then when people enhance or fix the feature, I can ask them to update the test app too. The infrastruture is terribly trivial at present - let's see how it evolves. - checkpoint/restart feature work. A note on this: this is a project by various mad Russians to perform c/r mainly from userspace, with various oddball helper code added into the kernel where the need is demonstrated. So rather than some large central lump of code, what we have is little bits and pieces popping up in various places which either expose something new or which permit something which is normally kernel-private to be modified. The overall project is an ongoing thing. I've judged that the size and scope of the thing means that we're more likely to be successful with it if we integrate the support into mainline piecemeal rather than allowing it all to develop out-of-tree. However I'm less confident than the developers that it will all eventually work! So what I'm asking them to do is to wrap each piece of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all eventually comes to tears and the project as a whole fails, it should be a simple matter to go through and delete all trace of it. This lot pretty much wraps up the -rc1 merge for me. * akpm: (96 commits) unlzo: fix input buffer free ramoops: update parameters only after successful init ramoops: fix use of rounddown_pow_of_two() c/r: prctl: add PR_SET_MM codes to set up mm_struct entries c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4 c/r: introduce CHECKPOINT_RESTORE symbol selftests: new x86 breakpoints selftest selftests: new very basic kernel selftests directory radix_tree: take radix_tree_path off stack radix_tree: remove radix_tree_indirect_to_ptr() dio: optimize cache misses in the submission path vfs: cache request_queue in struct block_device fs/direct-io.c: calculate fs_count correctly in get_more_blocks() drivers/parport/parport_pc.c: fix warnings panic: don't print redundant backtraces on oops sysctl: add the kernel.ns_last_pid control kdump: add udev events for memory online/offline include/linux/crash_dump.h needs elf.h kdump: fix crash_kexec()/smp_send_stop() race in panic() kdump: crashk_res init check for /sys/kernel/kexec_crash_size ...

KMSG_DUMP_KEXEC is useless because we already save kernel messages inside /proc/vmcore, and it is unsafe to allow modules to do other stuffs in a crash dump scenario.
