- atomic operations which both modify the variable and return something imply full smp memory barriers before and after the memory operations involved (failing atomic_cmpxchg, atomic_add_unless, etc don't imply a barrier because they don't modify the target). See Documentation/atomic_ops.txt. So remove extra barriers and branches. - All architectures support atomic_cmpxchg. This has no relation to __HAVE_ARCH_CMPXCHG. We can just take the atomic_cmpxchg path unconditionally This reduces a simple single threaded fastpath lock+unlock test from 590 cycles to 203 cycles on a ppc970 system.

page_cgroup_init() is called from mem_cgroup_init(). But at this point, we cannot call alloc_bootmem(). (and this caused panic at boot.) This patch moves page_cgroup_init() to init/main.c. Time table is following: == parse_args(). # we can trust mem_cgroup_subsys.disabled bit after this. .... cgroup_init_early() # "early" init of cgroup. .... setup_arch() # memmap is allocated. ... page_cgroup_init(); mem_init(); # we cannot call alloc_bootmem after this. .... cgroup_init() # mem_cgroup is initialized. == Before page_cgroup_init(), mem_map must be initialized. So, I added page_cgroup_init() to init/main.c directly. (*) maybe this is not very clean but - cgroup_init_early() is too early - in cgroup_init(), we have to use vmalloc instead of alloc_bootmem(). use of vmalloc area in x86-32 is important and we should avoid very large vmalloc() in x86-32. So, we want to use alloc_bootmem() and added page_cgroup_init() directly to init/main.c [akpm@linux-foundation.org: remove unneeded/bad mem_cgroup_subsys declaration] [akpm@linux-foundation.org: fix build] Acked-by: NBalbir Singh <balbir@linux.vnet.ibm.com> Tested-by: NBalbir Singh <balbir@linux.vnet.ibm.com> Signed-off-by: NKAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

When a checkpointing IO fails, current JBD code doesn't check the error and continue journaling. This means latest metadata can be lost from both the journal and filesystem. This patch leaves the failed metadata blocks in the journal space and aborts journaling in the case of log_do_checkpoint(). To achieve this, we need to do: 1. don't remove the failed buffer from the checkpoint list where in the case of __try_to_free_cp_buf() because it may be released or overwritten by a later transaction 2. log_do_checkpoint() is the last chance, remove the failed buffer from the checkpoint list and abort the journal 3. when checkpointing fails, don't update the journal super block to prevent the journaled contents from being cleaned. For safety, don't update j_tail and j_tail_sequence either 4. when checkpointing fails, notify this error to the ext3 layer so that ext3 don't clear the needs_recovery flag, otherwise the journaled contents are ignored and cleaned in the recovery phase 5. if the recovery fails, keep the needs_recovery flag 6. prevent cleanup_journal_tail() from being called between __journal_drop_transaction() and journal_abort() (a race issue between journal_flush() and __log_wait_for_space() Signed-off-by: NHidehiro Kawai <hidehiro.kawai.ez@hitachi.com> Acked-by: NJan Kara <jack@suse.cz> Cc: <linux-ext4@vger.kernel.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Slot detection drivers can co-exist with hotplug drivers. The names of the detected/claimed slots may be different depending on module load order. For legacy reasons, we need to allow hotplug drivers to override the slot name if a detection driver is loaded first (and they find the same slots). Creating and overriding slot names should be an atomic operation, otherwise you get a locking nightmare as various drivers race to call pci_create_slot(). pci_create_slot() is already serialized by grabbing the pci_bus_sem. We update the API and add a 'hotplug' param, which is: set if the caller is a hotplug driver NULL if the caller is a detection driver pci_create_slot() does not actually use the 'hotplug' parameter in this patch. A later patch will add the logic that uses it.

Sometimes, it's necessary to enable software's ability to quiesce and reset endpoint hardware with function-level granularity, so provide support for it. The patch implement Function Level Reset(FLR) feature following PCI-e spec. And this is the first step. We would add more generic method, like D0/D3, to allow more devices support this function. The patch contains two functions. pcie_reset_function() is the new driver API, and, contains some action to quiesce a device. The other function is a helper: pcie_execute_reset_function() just executes the reset for a particular device function. Current the usage model is in KVM. Function reset is necessary for assigning device to a guest, or moving it between partitions. For Function Level Reset(FLR), please refer to PCI Express spec chapter 6.6.2.

Maybe the incorrect power state is returned on the bogus bios, which is different with the real power state. For example: the bios returns D0 state and the real power state is D3. OS expects to set the device to D0 state. In such case if OS uses the power state returned by the BIOS and checks the device power state very strictly in power transition, the device can't be transited to the correct power state. So the boot option of "acpi.power_nocheck=1" is added to avoid checking the device power in the course of device power transition. http://bugzilla.kernel.org/show_bug.cgi?id=8049 http://bugzilla.kernel.org/show_bug.cgi?id=11000Signed-off-by: NZhao Yakui <yakui.zhao@intel.com> Signed-off-by: NZhang Rui <rui.zhang@intel.com> Signed-off-by: NLi Shaohua <shaohua.li@intel.com> Signed-off-by: NAndi Kleen <ak@linux.intel.com> Signed-off-by: NLen Brown <len.brown@intel.com>
