# commit a74e6a014c9d4d4161061f770c9b4f98372ac778
# Merge: 9b1ea29bc0d7 78c7cccaab9d
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Wed Mar 10 13:15:16 2021 -0800

#     Merge tag 's390-5.12-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
#     
#     Pull s390 fixes from Heiko Carstens:
#     
#      - fix various user space visible copy_to_user() instances which return
#        the number of bytes left to copy instead of -EFAULT
#     
#      - make TMPFS_INODE64 available again for s390 and alpha, now that both
#        architectures have been switched to 64-bit ino_t (see commit
#        96c0a6a72d18: "s390,alpha: switch to 64-bit ino_t")
#     
#      - make sure to release a shared hypervisor resource within the zcore
#        device driver also on restart and power down; also remove unneeded
#        surrounding debugfs_create return value checks
#     
#      - for the new hardware counter set device driver rename the uapi header
#        file to be a bit more generic; also remove 60 second read limit which
#        is not really necessary and without the limit the interface can be
#        easier tested
#     
#      - some small cleanups, the largest being to convert all long long in
#        our time and idle code to longs
#     
#      - update defconfigs
#     
#     * tag 's390-5.12-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
#       s390: remove IBM_PARTITION and CONFIGFS_FS from zfcpdump defconfig
#       s390: update defconfigs
#       s390,alpha: make TMPFS_INODE64 available again
#       s390/cio: return -EFAULT if copy_to_user() fails

#       s390/crypto: return -EFAULT if copy_to_user() fails
#       s390/cio: return -EFAULT if copy_to_user() fails

#       s390/zcore: release dump save area on restart or power down
#       s390/zcore: no need to check return value of debugfs_create functions
#       s390/cpumf: remove 60 seconds read limit
#       s390/topology: remove always false if check
#       s390/time,idle: get rid of unsigned long long
