The original Direct IO issue was discovered by Chris Mason @ Facebook on a production workload which mixed buffered reads with direct reads and writes IO to the same file. The fix for that exposed other issues with page invalidation (exposed by millions of fsx operations) failing due to dirty buffers beyond EOF. Finally, the collapse_range code could also cause problems due to racing writeback changing the extent map while it was being shifted around. The commits for that problem are simple mitigation fixes that prevent the problem from occuring. A more robust fix for 3.18 that addresses the underlying problem is currently being worked on by Brian.

2014-09-06timekeeping: Update timekeeper before updating vsyscall and pvclockThomas Gleixner1-2/+3
The update_walltime() code works on the shadow timekeeper to make the seqcount protected region as short as possible. But that update to the shadow timekeeper does not update all timekeeper fields because it's sufficient to do that once before it becomes life. One of these fields is tkr.base_mono. That stays stale in the shadow timekeeper unless an operation happens which copies the real timekeeper to the shadow. The update function is called after the update calls to vsyscall and pvclock. While not correct, it did not cause any problems because none of the invoked update functions used base_mono. commit cbcf2dd3b3d4 (x86: kvm: Make kvm_get_time_and_clockread() nanoseconds based) changed that in the kvm pvclock update function, so the stale mono_base value got used and caused kvm-clock to malfunction. Put the update where it belongs and fix the issue.

2014-09-05mm: memcontrol: revert use of root_mem_cgroup res_counterJohannes Weiner1-25/+78
Dave Hansen reports a massive scalability regression in an uncontained page fault benchmark with more than 30 concurrent threads, which he bisected down to 05b843012335 ("mm: memcontrol: use root_mem_cgroup res_counter") and pin-pointed on res_counter spinlock contention. That change relied on the per-cpu charge caches to mostly swallow the res_counter costs, but it's apparent that the caches don't scale yet. Revert memcg back to bypassing res_counters on the root level in order to restore performance for uncontained workloads.

2014-09-05Export sync_filesystem() for modular ->remount_fs() useAnton Altaparmakov1-1/+1
This patch changes sync_filesystem() to be EXPORT_SYMBOL(). The reason this is needed is that starting with 3.15 kernel, due to Theodore Ts'o's commit 02b9984d6408 ("fs: push sync_filesystem() down to the file system's remount_fs()"), all file systems that have dirty data to be written out need to call sync_filesystem() from their ->remount_fs() method when remounting read-only. As this is now a generically required function rather than an internal only function it should be EXPORT_SYMBOL() so that all file systems can call it.

2014-09-05nohz: Restore NMI safe local irq work for local nohz kickFrederic Weisbecker2-6/+15
The local nohz kick is currently used by perf which needs it to be NMI-safe. Recent commit though (7d1311b93e58ed55f3a31cc8f94c4b8fe988a2b9) changed its implementation to fire the local kick using the remote kick API. It was convenient to make the code more generic but the remote kick isn't NMI-safe.

2014-09-04ARM: dts: dra7-evm: Add vtt regulator supportLokesh Vutla1-1/+26
DRA7 evm REV G and later boards uses a vtt regulator for DDR3 termination and this is controlled by gpio7_11. This gpio is configured in boot loader. gpio7_11, which is only available only on Pad A22, in previous boards, is connected only to an unused pad on expansion connector EXP_P3 and is safe to be muxed as GPIO on all DRA7-evm versions (without a need to spin off another dts file). Since gpio7_11 is used to control VTT and should not be reset or kept in idle state during boot up else VTT will be disconnected and DDR gets corrupted. So, as part of this change, mark gpio7 as no-reset and no-idle on init.

2014-09-04ARM: dts: am437x-gp-evm: Use BCH16 ECC scheme instead of BCH8Roger Quadros1-1/+1
am437x-gp-evm uses a NAND chip with page size 4096 bytes and spare area of 225 bytes per page. For such a setup it is preferrable to use BCH16 ECC scheme over BCH8. This also makes it compatible with ROM code ECC scheme so we can boot with NAND after flashing from kernel.

This reverts commit 150b8be3cda54412ad7b54f5392b513b25c0aaa7. The I2C core's per-adapter locks can't protect from IRQs, so the driver still needs a spinlock to protect the register accesses.

2014-09-03toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store()Dan Carpenter1-6/+12
The current code just returns -EINVAL because mode can't be equal to both 1 and 2. Also this function is messy so I have cleaned it up: 1) Remove initializers like "int time = -1". Initializing variables to garbage values turns off GCC's uninitialized variable warnings so it can lead to bugs. 2) Use kstrtoint() instead of sscanf(). 3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1 and 2. 4) Don't check for "mode == -1" because that can't happen. 5) Preserve the error code from toshiba_kbd_illum_status_set().
