* Replace <asm/uaccess.h> with <linux/uaccess.h> globallyLinus Torvalds2018-11-292-2/+2
| | | | | | | | | | | | | | This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>' sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

* modpost: remove all traces of cpuinit/cpuexit sectionsPaul Gortmaker2017-12-261-12/+0
| | | | | | | | | | | | | | Delete all audit rules that were checking how the .cpuXYZ related sections were inter-operating with other __init like sections, now that __cpuinit is gone. Update the linker script to not have any knowledge of .cpuinit sections.

* Finally eradicate CONFIG_HOTPLUGStephen Rothwell2017-12-221-20/+0
| | | | | | | | | | | | | | | | | | | Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"), it has been basically impossible to build a kernel with CONFIG_HOTPLUG turned off. Remove all the remaining references to it.

* asm-generic: rwsem: ensure sem->cnt is only accessed via atomic_long_*Will Deacon2016-09-131-1/+1
| | | | | | | | | The asm-generic rwsem implementation directly acceses sem->cnt when performing a __down_read_trylock operation. Whilst this is probably safe on all architectures, we should stick to the atomic_long_* API and use atomic_long_read instead. Signed-off-by: Will Deacon <will.deacon@arm.com>
