The following non-security bugs were fixed:

• bpf: fix verification of indirect var-off stack access (git-fixes).
• bpf: guard stack limits against 32bit overflow (git-fixes).
• drop 2 git-fixes patches which are suspicious to introduce regression reported in bsc#1219073
• fix unresolved hunks in readme.branch
• kvm: vmx: move verw closer to vmentry for mds mitigation (git-fixes).
• kvm: vmx: use bt+jnc, i.e. eflags.cf to select vmresume vs. vmlaunch (git-fixes).
• nfs: avoid infinite loop in pnfsupdatelayout (bsc#1219633).
• nvme: move nvmestopkeep_alive() back to original position (bsc#1211515).
• nvme: remove nvmeallocrequest and nvmeallocrequest_qid (bsc#1214064).
• nvme: start keep-alive after admin queue setup (bsc#1211515).
• readme.branch: use correct mail for roy
• rpm/kernel-binary.spec.in: install scripts/gdb when enabled in config (bsc#1219653) they are put into -devel subpackage. and a proper link to /usr/share/gdb/auto-load/ is created.
• x86/asm: add asmrip() macro for x86-64 (%rip) suffix (git-fixes).
• x86/bugs: add asm helpers for executing verw (git-fixes).
• x86/bugs: use alternative() instead of mdsuserclear static key (git-fixes). also add the removed mdsuserclear symbol to kabi severities as it is exposed just for kvm module and is generally a core kernel component so removing it is low risk.
• x86/entry_32: add verw just before userspace transition (git-fixes).
• x86/entry_64: Add VERW just before userspace transition (git-fixes).
