* Replace <asm/uaccess.h> with <linux/uaccess.h> globallyLinus Torvalds2018-11-293-3/+3
| | | | | | | | | | | | | | 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.

* s390: TASK_SIZE for kernel threadsMartin Schwidefsky2017-07-041-1/+2
| | | | | | | | | | | | | commit fb94a687d96c570d46332a4a890f1dcb7310e643 upstream. Return a sensible value if TASK_SIZE if called from a kernel thread. This gets us around an issue with copy_mount_options that does a magic size calculation "TASK_SIZE - (unsigned long)data" while in a kernel thread and data pointing to kernel space.

* KVM: s390: fix task size checkMartin Schwidefsky2017-07-041-0/+2
| | | | | | | | | | | | | | The gmap_map_segment function uses PGDIR_SIZE in the check for the maximum address in the tasks address space. This incorrectly limits the amount of memory usable for a kvm guest to 4TB. The correct limit is (1UL << 53). As the TASK_SIZE has different values (4TB vs 8PB) dependent on the existance of the fourth page table level, create a new define 'TASK_MAX_SIZE' for (1UL << 53).

* locking/mcs: Allow architecture specific asm files to be used for contended caseTim Chen2017-05-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows each architecture to add its specific assembly optimized arch_mcs_spin_lock_contended and arch_mcs_spinlock_uncontended for MCS lock and unlock functions.
