This patch introduces .enable_irq and .disable_irq into struct arm_pmu_platdata, so platform specific irq enablement can be handled after request_irq, and platform specific irq disablement can be handled before free_irq. This patch is for support of pmu irq routed from CTI on omap4.

This patch updates the ARMv7 perf event numbers so that: (1) A consistent naming scheme is used between different CPUs. (2) Only events actually used by Linux are described. (3) Where possible, architected events are used in preference to CPU-specific events. This results in the removal of a load of unused, hardcoded data and makes it more clear as to which events are supported on each PMU.

The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

Commit 4a54c8c1 introduced raid-repair, killing the individual readpage_io_failed_hook entries from inode.c and disk-io.c. Commit 4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to disk-io.c. The raid-repair commit had logic to disable raid-repair, if readpage_io_failed_hook is set. Thus, the readahead commit effectively disabled raid-repair for meta data. This commit changes the logic to always attempt raid-repair when needed and call the readpage_io_failed_hook in case raid-repair fails. This is much more straight forward and should have been like that from the beginning.

The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a SWP instruction will cause an oops when the kprobes emulation code executes an undefined instruction. As the SWP instruction should be rare or non-existent in kernels for ARMv6 and later, we can simply avoid these problems by not allowing probing of these.

There is a kprobes testcase for the instruction "strd r2, [r3], r4". This has unpredictable behaviour as it uses r3 for register writeback addressing and also stores it to memory. On a cortex A9, this testcase would fail because the instruction writes the updated value of r3 to memory, whereas the kprobes emulation code writes the original value. Fix this by changing testcase to used r5 instead of r3.

We test whether a block group has enough free space to hold the requested block, but when we're doing clustered allocation, we can save some cycles by testing whether it has enough room for the cluster upfront, otherwise we end up attempting to set up a cluster and failing. Only in the NO_EMPTY_SIZE loop do we attempt an unclustered allocation, and by then we'll have zeroed the cluster size, so this patch won't stop us from using the block group as a last resort.

The field that indicates the size of the largest contiguous chunk of free space in the cluster is not initialized when setting up bitmaps, it's only increased when we find a larger contiguous chunk. We end up retaining a larger value than appropriate for highly-fragmented clusters, which may cause pointless searches for large contiguous groups, and even cause clusters that do not meet the density requirements to be set up.

We're failing to create clusters with bitmaps because setup_cluster_no_bitmap checks that the list is empty before inserting the bitmap entry in the list for setup_cluster_bitmap, but the list field is only initialized when it is restored from the on-disk free space cache, or when it is written out to disk. Besides a potential race condition due to the multiple use of the list field, filesystem performance severely degrades over time: as we use up all non-bitmap free extents, the try-to-set-up-cluster dance is done at every metadata block allocation. For every block group, we fail to set up a cluster, and after failing on them all up to twice, we fall back to the much slower unclustered allocation. To make matters worse, before the unclustered allocation, we try to create new block groups until we reach the 1% threshold, which introduces additional bitmaps and thus block groups that we'll iterate over at each metadata block request.

When I ran the xfstests, I found the test tasks was blocked on meta-data reservation. By debugging, I found the reason of this bug: start transaction | v reserve meta-data space | v flush delay allocation -> iput inode -> evict inode ^ | | v wait for delay allocation flush <- reserve meta-data space And besides that, the flush on evicting inode will block the thread, which is reclaiming the memory, and make oom happen easily.
