2017-05-12drm/nouveau/tmr: avoid processing completed alarms when adding a new oneBen Skeggs1-3/+13
The idea here was to avoid having to "manually" program the HW if there's a new earliest alarm. This was lazy and bad, as it leads to loads of fun races between inter-related callers (ie. therm). Turns out, it's not so difficult after all. Go figure ;) Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: stable@vger.kernel.org
2017-05-12drm/nouveau/tmr: fix corruption of the pending list when rescheduling an alarmBen Skeggs1-7/+10
At least therm/fantog "attempts" to work around this issue, which could lead to corruption of the pending alarm list. Fix it properly by not updating the timestamp without the lock held, or trying to add an already pending alarm to the pending alarm list....

2017-05-12drm/nouveau/tmr: handle races with hw when updating the next alarm timeBen Skeggs1-10/+16
If the time to the next alarm is short enough, we could race with HW and end up with an ~4 second delay until it triggers. Fix this by checking again after we update HW. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: stable@vger.kernel.org

2017-05-12drm/nouveau/kms/nv50: skip core channel cursor update on position-only changesBen Skeggs1-3/+7
The DRM core used to only call prepare_fb/cleanup_fb() when a plane's framebuffer changed, which achieved the desired effect. It's apparently now up to the driver to decide on its own. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: stable@vger.kernel.org [4.11+]

2017-05-11xen: adjust early dom0 p2m handling to xen hypervisor behaviorJuergen Gross1-3/+4
When booted as pv-guest the p2m list presented by the Xen is already mapped to virtual addresses. In dom0 case the hypervisor might make use of 2M- or 1G-pages for this mapping. Unfortunately while being properly aligned in virtual and machine address space, those pages might not be aligned properly in guest physical address space. So when trying to obtain the guest physical address of such a page pud_pfn() and pmd_pfn() must be avoided as those will mask away guest physical address bits not being zero in this special case.

2017-05-11x86/amd: don't set X86_BUG_SYSRET_SS_ATTRS when running under XenJuergen Gross2-3/+3
When running as Xen pv guest X86_BUG_SYSRET_SS_ATTRS must not be set on AMD cpus. This bug/feature bit is kind of special as it will be used very early when switching threads. Setting the bit and clearing it a little bit later leaves a critical window where things can go wrong. This time window has enlarged a little bit by using setup_clear_cpu_cap() instead of the hypervisor's set_cpu_features callback. It seems this larger window now makes it rather easy to hit the problem. The proper solution is to never set the bit in case of Xen.

2017-05-10filesystem-dax: fix broken __dax_zero_page_range() conversionDan Williams1-2/+2
The conversion of __dax_zero_page_range() to 'struct dax_operations' caused it to frequently fail. The mistake was treating the @size parameter as a dax mapping length rather than just a length of the clear_pmem() operation. The dax mapping length is assumed to be hard coded as PAGE_SIZE. Without this fix any page unaligned zeroing request will trigger a -EINVAL return from bdev_dax_pgoff().

2017-05-10libnvdimm, btt: ensure that initializing metadata clears poisonVishal Verma1-7/+47
If we had badblocks/poison in the metadata area of a BTT, recreating the BTT would not clear the poison in all cases, notably the flog area. This is because rw_bytes will only clear errors if the request being sent down is 512B aligned and sized. Make sure that when writing the map and info blocks, the rw_bytes being sent are of the correct size/alignment. For the flog, instead of doing the smaller log_entry writes only, first do a 'wipe' of the entire area by writing zeroes in large enough chunks so that errors get cleared.

2017-05-10libnvdimm: add an atomic vs process context flag to rw_bytesVishal Verma7-42/+53
nsio_rw_bytes can clear media errors, but this cannot be done while we are in an atomic context due to locking within ACPI. From the BTT, ->rw_bytes may be called either from atomic or process context depending on whether the calls happen during initialization or during IO. During init, we want to ensure error clearing happens, and the flag marking process context allows nsio_rw_bytes to do that. When called during IO, we're in atomic context, and error clearing can be skipped.

2017-05-10blk-mq: NVMe 512B/4K+T10 DIF/DIX format returns I/O error on dd with split opWen Xiong1-2/+2
When formatting NVMe to 512B/4K + T10 DIf/DIX, dd with split op returns "Input/output error". Looks block layer split the bio after calling bio_integrity_prep(bio). This patch fixes the issue. Below is how we debug this issue: (1)format nvme to 4K block # size with type 2 DIF (2)dd with block size bigger than 1024k. oflag=direct dd: error writing '/dev/nvme0n1': Input/output error We added some debug code in nvme device driver. It showed us the first op and the second op have the same bi and pi address. This is not correct. 1st op: nvme0n1 Op:Wr slba 0x505 length 0x100, PI ctrl=0x1400, dsmgmt=0x0, AT=0x0 & RT=0x505 Guard 0x00b1, AT 0x0000, RT physical 0x00000505 RT virtual 0x00002828 2nd op: nvme0n1 Op:Wr slba 0x605 length 0x1, PI ctrl=0x1400, dsmgmt=0x0, AT=0x0 & RT=0x605 ==> This op fails and subsequent 5 retires.. Guard 0x00b1, AT 0x0000, RT physical 0x00000605 RT virtual 0x00002828 With the fix, It showed us both of the first op and the second op have correct bi and pi address. 1st op: nvme2n1 Op:Wr slba 0x505 length 0x100, PI ctrl=0x1400, dsmgmt=0x0, AT=0x0 & RT=0x505 Guard 0x5ccb, AT 0x0000, RT physical 0x00000505 RT virtual 0x00002828 2nd op: nvme2n1 Op:Wr slba 0x605 length 0x1, PI ctrl=0x1400, dsmgmt=0x0, AT=0x0 & RT=0x605 Guard 0xab4c, AT 0x0000, RT physical 0x00000605 RT virtual 0x00003028 Signed-off-by: Wen Xiong <wenxiong@linux.vnet.ibm.com> Signed-off-by: Jens Axboe <axboe@fb.com>
