2014-12-02mm: frontswap: invalidate expired data on a dup-store failureWeijie Yang
If a frontswap dup-store failed, it should invalidate the expired page in the backend, or it could trigger some data corruption issue. Such as: 1. use zswap as the frontswap backend with writeback feature 2. store a swap page(version_1) to entry A, success 3. dup-store a newer page(version_2) to the same entry A, fail 4. use __swap_writepage() write version_2 page to swapfile, success 5. zswap do shrink, writeback version_1 page to swapfile 6. version_2 page is overwrited by version_1, data corrupt. This patch fixes this issue by invalidating expired data immediately when meet a dup-store failure.

2014-12-02NFC: NCI: Fix max length of General Bytes in ATR_RESJulien Lefrique
The maximum size of ATR_REQ and ATR_RES is 64 bytes. The maximum number of General Bytes is calculated by the maximum number of data bytes in the ATR_REQ/ATR_RES, substracted by the number of mandatory data bytes. ATR_REQ: 16 mandatory data bytes, giving a maximum of 48 General Bytes. ATR_RES: 17 mandatory data bytes, giving a maximum of 47 General Bytes. Regression introduced in commit a99903ec.

2014-12-02block: fix regression where bio_integrity_process uses wrong bio_vec iteratorDarrick J. Wong
bio integrity handling is broken on a system with LVM layered atop a DIF/DIX SCSI drive because device mapper clones the bio, modifies the clone, and sends the clone to the lower layers for processing. However, the clone bio has bi_vcnt == 0, which means that when the sd driver calls bio_integrity_process to attach DIX data, the for_each_segment_all() call (which uses bi_vcnt) returns immediately and random garbage is sent to the disk on a disk write. The disk of course returns an error. Therefore, teach bio_integrity_process() to use bio_for_each_segment() to iterate the bio_vecs, since the per-bio iterator tracks which bio_vecs are associated with that particular bio. The integrity handling code is effectively part of the "driver" (it's not the bio owner), so it must use the correct iterator function. v2: Fix a compiler warning about abandoned local variables. This patch supersedes "block: bio_integrity_process uses wrong bio_vec iterator". Patch applies against 3.18-rc6. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Acked-by: Martin K.

2014-12-02iwlwifi: pcie: support more monitor types dumpingLiad Kaufman
Until this patch, dumping the monitor data could be done only for PCIe external (DRAM) mode in 7000 HW family. This patch allows to pull the monitor data also on other families, and also to pull the monitor data if an internal buffer is used.

2014-12-02sb_edac: Fix discovery of top-of-low-memory for HaswellTony Luck
Haswell moved the TOLM/TOHM registers to a different device and offset. The sb_edac driver accounted for the change of device, but not for the new offset. There was also a typo in the constant to fill in the low 26 bits (was 0x1ffffff, should be 0x3ffffff). This resulted in a bogus value for the top of low memory: EDAC DEBUG: get_memory_layout: TOLM: 0.032 GB (0x0000000001ffffff) which would result in EDAC refusing to translate addresses for errors above the bogus value and below 4GB: sbridge MC3: HANDLING MCE MEMORY ERROR sbridge MC3: CPU 0: Machine Check Event: 0 Bank 7: 8c00004000010090 sbridge MC3: TSC 0 sbridge MC3: ADDR 2000000 sbridge MC3: MISC 523eac86 sbridge MC3: PROCESSOR 0:306f3 TIME 1414600951 SOCKET 0 APIC 0 MC3: 1 CE Error at TOLM area, on addr 0x02000000 on any memory ( page:0x0 offset:0x0 grain:32 syndrome:0x0) With the fix we see the correct TOLM value: DEBUG: get_memory_layout: TOLM: 2.048 GB (0x000000007fffffff) and we decode address 2000000 correctly: sbridge MC3: HANDLING MCE MEMORY ERROR sbridge MC3: CPU 0: Machine Check Event: 0 Bank 7: 8c00004000010090 sbridge MC3: TSC 0 sbridge MC3: ADDR 2000000 sbridge MC3: MISC 523e1086 sbridge MC3: PROCESSOR 0:306f3 TIME 1414601319 SOCKET 0 APIC 0 DEBUG: get_memory_error_data: SAD interleave package: 0 = CPU socket 0, HA 0, shiftup: 0 DEBUG: get_memory_error_data: TAD#0: address 0x0000000002000000 < 0x000000007fffffff, socket interleave 1, channel interleave 4 (offset 0x00000000), index 0, base ch: 0, ch mask: 0x01 DEBUG: get_memory_error_data: RIR#0, limit: 4.095 GB (0x00000000ffffffff), way: 1 DEBUG: get_memory_error_data: RIR#0: channel address 0x00200000 < 0xffffffff, RIR interleave 0, index 0 DEBUG: sbridge_mce_output_error: area:DRAM err_code:0001:0090 socket:0 channel_mask:1 rank:0 MC3: 1 CE memory read error on CPU_SrcID#0_Channel#0_DIMM#0 (channel:0 slot:0 page:0x2000 offset:0x0 grain:32 syndrome:0x0 - area:DRAM err_code:0001:0090 socket:0 channel_mask:1 rank:0) Signed-off-by: Tony Luck <tony.luck@intel.com> Acked-by: Aristeu Rozanski <aris@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
