June 2019 - Linux-stable-mirror

by Evalds Iodzevics

Hi back in the December of 2016 there was commit "1c52d859cb2d417e7216d3e56bb7fea88444cec9" witch was followed shortly by "c198b121b1a1d7a7171770c634cd49191bac4477" Unfortunately only the first commit was later included in long-term kernel branches such as 4.4 and 4.9 witch left some of microcode functionality broken on 32 bit systems I guess it should be easily fixed by including "c198b121b1a1d7a7171770c634cd49191bac4477" in those branches

[PATCH] Input: i8042 - disable KBD port on Late-2016 Razer Blade Stealth

by Lyude Paul

The late 2016 model of the Razer Blade Stealth has a built-in USB keyboard, but for some reason the BIOS exposes an i8042 controller with a connected KBD port. While this fake AT Keyboard device doesn't appear to report any events, attempting to change the state of the caps lock LED on it from on to off causes the entire system to hang. So, introduce a quirk table for disabling keyboard probing by default, i8042_dmi_nokbd_table, and add this specific model of Razer laptop to that table.

[PATCH v2] iio: imu: mpu6050: add missing available scan masks

[PATCH 1/2 RESEND3] perf/x86/amd/uncore: Do not set ThreadMask and SliceMask for non-L3 PMCs

by Phillips, Kim

From: Kim Phillips <kim.phillips(a)amd.com> Commit d7cbbe49a930 ("perf/x86/amd/uncore: Set ThreadMask and SliceMask for L3 Cache perf events") enables L3 PMC events for all threads and slices by writing 1s in ChL3PmcCfg (L3 PMC PERF_CTL) register fields. Those bitfields overlap with high order event select bits in the Data Fabric PMC control register, however. So when a user requests raw Data Fabric events (-e amd_df/event=0xYYY/), the two highest order bits get inadvertently set, changing the counter select to events that don't exist, and for which no counts are read. This patch changes the logic to write the L3 masks only when dealing with L3 PMC counters. AMD Family 16h and below Northbridge (NB) counters were not affected.

[PATCH] mm/mmap: fix the adjusted length error

by jianhong chen

In linux version 4.4, a 32-bit process may fail to allocate 64M hugepage memory by function shmat even though there is a 64M memory gap in the process. It is the adjusted length that causes the problem, introduced from commit db4fbfb9523c935 ("mm: vm_unmapped_area() lookup function"). Accounting for the worst case alignment overhead, function unmapped_area and unmapped_area_topdown adjust the search length before searching for available vma gap. This is an estimated length, sum of the desired length and the longest alignment offset, which can cause misjudgement if the system has very few virtual memory left. For example, if the longest memory gap available is 64M, we can’t get it from the system by allocating 64M hugepage memory via shmat function. The reason is that it requires a longger length, the sum of the desired length(64M) and the longest alignment offset. To fix this error ,we can calculate the alignment offset of gap_start or gap_end to get a desired gap_start or gap_end value, before searching for the available gap. In this way, we don't need to adjust the search length. Problem reproduces procedure: 1. allocate a lot of virtual memory segments via shmat and malloc 2. release one of the biggest memory segment via shmdt 3. attach the biggest memory segment via shmat e.g. process maps: 00008000-00009000 r-xp 00000000 00:12 3385 /tmp/memory_mmap 00011000-00012000 rw-p 00001000 00:12 3385 /tmp/memory_mmap 27536000-f756a000 rw-p 00000000 00:00 0 f756a000-f7691000 r-xp 00000000 01:00 560 /lib/libc-2.11.1.so f7691000-f7699000 ---p 00127000 01:00 560 /lib/libc-2.11.1.so f7699000-f769b000 r--p 00127000 01:00 560 /lib/libc-2.11.1.so f769b000-f769c000 rw-p 00129000 01:00 560 /lib/libc-2.11.1.so f769c000-f769f000 rw-p 00000000 00:00 0 f769f000-f76c0000 r-xp 00000000 01:00 583 /lib/libgcc_s.so.1 f76c0000-f76c7000 ---p 00021000 01:00 583 /lib/libgcc_s.so.1 f76c7000-f76c8000 rw-p 00020000 01:00 583 /lib/libgcc_s.so.1 f76c8000-f76e5000 r-xp 00000000 01:00 543 /lib/ld-2.11.1.so f76e9000-f76ea000 rw-p 00000000 00:00 0 f76ea000-f76ec000 rw-p 00000000 00:00 0 f76ec000-f76ed000 r--p 0001c000 01:00 543 /lib/ld-2.11.1.so f76ed000-f76ee000 rw-p 0001d000 01:00 543 /lib/ld-2.11.1.so f7800000-f7a00000 rw-s 00000000 00:0e 0 /SYSV000000ea (deleted) fba00000-fca00000 rw-s 00000000 00:0e 65538 /SYSV000000ec (deleted) fca00000-fce00000 rw-s 00000000 00:0e 98307 /SYSV000000ed (deleted) fce00000-fd800000 rw-s 00000000 00:0e 131076 /SYSV000000ee (deleted) ff913000-ff934000 rw-p 00000000 00:00 0 [stack] ffff0000-ffff1000 r-xp 00000000 00:00 0 [vectors] from 0xf7a00000 to fba00000, it has 64M memory gap, but we can't get it from kernel.
