[PATCH 3/5] sd_zbc: Log zone reset failures

A zone reset only fails for conventional zones. Resetting a conventional zone indicates a bug in the software that submitted the zone reset so the information about a zone reset failure is useful information.

[PATCH 2/5] sd_zbc: Let the SCSI core handle ILLEGAL REQUEST / ASC 0x21

by Bart Van Assche

scsi_io_completion() translates the sense key ILLEGAL REQUEST / ASC 0x21 into ACTION_FAIL. That means that setting cmd->allowed to zero in sd_zbc_complete() for this sense code / ASC combination is not necessary. Hence remove the code that resets cmd->allowed from sd_zbc_complete().

[PATCH 24/24] x86/spectre_v2: Don't check microcode versions when running under hypervisors

by Youquan Song

From: Konrad Rzeszutek Wilk <konrad.wilk(a)oracle.com> (cherry picked from commit 36268223c1e9981d6cfc33aff8520b3bde4b8114) As: 1) It's known that hypervisors lie about the environment anyhow (host mismatch) 2) Even if the hypervisor (Xen, KVM, VMWare, etc) provided a valid "correct" value, it all gets to be very murky when migration happens (do you provide the "new" microcode of the machine?). And in reality the cloud vendors are the ones that should make sure that the microcode that is running is correct and we should just sing lalalala and trust them.

[PATCH 23/23] KVM/VMX: Optimize vmx_vcpu_run() and svm_vcpu_run() by marking the RDMSR path as unlikely()

by Youquan Song

From: Paolo Bonzini <pbonzini(a)redhat.com> commit 946fbbc13dce68902f64515b610eeb2a6c3d7a64 upstream. vmx_vcpu_run() and svm_vcpu_run() are large functions, and giving branch hints to the compiler can actually make a substantial cycle difference by keeping the fast path contiguous in memory. With this optimization, the retpoline-guest/retpoline-host case is about 50 cycles faster.

[PATCH v2 1/2] pinctrl/samsung: Correct EINTG banks order

by Paweł Chmiel

All banks with GPIO interrupts should be at beginning of bank array and without any other types of banks between them. This order is expected by exynos_eint_gpio_irq, when doing interrupt group to bank translation. Otherwise, kernel NULL pointer dereference would happen when trying to handle interrupt, due to wrong bank being looked up. Observed on s5pv210, when trying to handle gpj0 interrupt, where kernel was mapping it to gpi bank.
