- Rework copy_oldmem_page() callback to take an iov_iter. This includes few prerequisite updates and fixes to the oldmem reading code. - Rework cpufeature implementation to allow for various CPU feature indications, which is not only limited to hardware capabilities, but also allows CPU facilities. - Use the cpufeature rework to autoload Ultravisor module when CPU facility 158 is available. - Add ELF note type for encrypted CPU state of a protected virtual CPU. The zgetdump tool from s390-tools package will decrypt the CPU state using a Customer Communication Key and overwrite respective notes to make the data accessible for crash and other debugging tools. - Use vzalloc() instead of vmalloc() + memset() in ChaCha20 crypto test. - Fix incorrect recovery of kretprobe modified return address in stacktrace. - Switch the NMI handler to use generic irqentry_nmi_enter() and irqentry_nmi_exit() helper functions. - Rework the cryptographic Adjunct Processors (AP) pass-through design to support dynamic changes to the AP matrix of a running guest as well as to implement more of the AP architecture. - Minor boot code cleanups. - Grammar and typo fixes to hmcdrv and tape drivers. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCYu4dRBccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8DnlAP45Sk4cE35T+Z0vdHE2f0uMXE/p uHNjS3fDZOQVFJ2jZwEA99xPF5qPCttbR/b1VHsMSb30684IT1A4PC7y05kgfAw= =jCc3 -----END PGP SIGNATURE----- Merge tag 's390-5.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Rework copy_oldmem_page() callback to take an iov_iter.
