2018-07-19staging: gasket: gasket_wait_with_reschedule use 32 bits of retry countTodd Poynor

2018-07-19staging: gasket: gasket_wait_with_reschedule simplify logicTodd Poynor
gasket_wait_with_reschedule() is a little more clear if we just return directly when the waited-for condition is hit. This also allows the following condition check to be removed and identation of the conditionally-executed code to be reduced.

2018-07-16staging: android: ashmem: Shrink directly through shmem_fallocateTobias Lindskog
When ashmem_shrink is called from direct reclaim on a user thread, a call to do_fallocate will check for permissions against the security policy of that user thread. It can thus fail by chance if called on a thread that isn't permitted to modify the relevant ashmem areas. Because we know that we have a shmem file underneath, call the shmem implementation of fallocate directly instead of going through the user-space interface for fallocate.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes Two omap fixes for v4.18-rc cycle Turns out the recent patches for ARM branch predictor hardening are not working on omap5 and dra7 as planned because the secondary CPU is parked to the bootrom code. We can't configure it in the bootloader. So we must enable invalidates of BTB for omap5 and dra7 secondary core in the kernel. And there's a fix for reserved register access for am3517.

2018-07-14reiserfs: fix buffer overflow with long warning messagesEric Biggers
ReiserFS prepares log messages into a 1024-byte buffer with no bounds checks. Long messages, such as the "unknown mount option" warning when userspace passes a crafted mount options string, overflow this buffer. This causes KASAN to report a global-out-of-bounds write. Fix it by truncating messages to the buffer size.
