Merge tag 's390-6.5-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 fixes from Heiko Carstens:
- Fix per vma lock fault handling: add missing !(fault & VM_FAULT_ERROR)
check to fault handler to prevent error handling for return values
that don't indicate an error
- Use kfree_sensitive() instead of kfree() in paes crypto code to clear
memory that may contain keys before freeing it
- Fix reply buffer size calculation for CCA replies in zcrypt device
driver
