The thermal sensor has an accuracy of ±5°C and there can be a temperature difference of 1 or 2 degrees between Tjmax and the thermal sensor due to the location of the latter. This means that 95°C is a safer value to use.

This reverts commit 04e35f4495dd560db30c25efca4eecae8ec8c375. SELinux runs with secureexec for all non-"noatsecure" domain transitions, which means lots of processes end up hitting the stack hard-limit change that was introduced in order to fix a race with prlimit(). That race fix will need to be redesigned.

2017-12-17cramfs: fix MTD dependencyArnd Bergmann
With CONFIG_MTD=m and CONFIG_CRAMFS=y, we now get a link failure: fs/cramfs/inode.o: In function `cramfs_mount': inode.c:(.text+0x220): undefined reference to `mount_mtd' fs/cramfs/inode.o: In function `cramfs_mtd_fill_super': inode.c:(.text+0x6d8): undefined reference to `mtd_point' inode.c:(.text+0xae4): undefined reference to `mtd_unpoint' This adds a more specific Kconfig dependency to avoid the broken configuration. Alternatively we could make CRAMFS itself depend on "MTD || !MTD" with a similar result.

2017-12-17x86/mm/kasan: Don't use vmemmap_populate() to initialize shadowAndrey Ryabinin
[ Note, this is a Git cherry-pick of the following commit: d17a1d97dc20: ("x86/mm/kasan: don't use vmemmap_populate() to initialize shadow") ... for easier x86 PTI code testing and back-porting. ] The KASAN shadow is currently mapped using vmemmap_populate() since that provides a semi-convenient way to map pages into init_top_pgt. However, since that no longer zeroes the mapped pages, it is not suitable for KASAN, which requires zeroed shadow memory. Add kasan_populate_shadow() interface and use it instead of vmemmap_populate(). Besides, this allows us to take advantage of gigantic pages and use them to populate the shadow, which should save us some memory wasted on page tables and reduce TLB pressure.

[ Note, this is a Git cherry-pick of the following commit: a47ba4d77e12 ("perf/x86: Enable free running PEBS for REGS_USER/INTR") ... for easier x86 PTI code testing and back-porting. ] Currently free running PEBS is disabled when user or interrupt registers are requested. Most of the registers are actually available in the PEBS record and can be supported. So we just need to check for the supported registers and then allow it: it is all except for the segment register. For user registers this only works when the counter is limited to ring 3 only, so this also needs to be checked.
