A fix and an email address update: - Prevent FPU state corruption. The condition in irq_fpu_usable() grants FPU usage when the FPU is not used in the kernel. That's just wrong as it does not take the fpregs_lock()'ed regions into account. If FPU usage happens within such a region from interrupt context, then the FPU state gets corrupted. That's a long standing bug, which got unearthed by the recent changes to the random code. - Josh wants to use his kernel.org email address
A fix and an email address update:
- Mark the NMI safe time accessors notrace to prevent tracer recursion
when they are selected as trace clocks.
- John Stultz has a new email address
Just a email address update for MAINTAINERS and mailmap.
A fix for the threaded interrupt core. A quick sequence of request/free_irq() can result in a hang because the interrupt thread did not reach the thread function and got stopped in the kthread core already. That leaves a state active counter arround which makes a invocation of synchronized_irq() on that interrupt hang forever. Ensure that the thread reached the thread function in request_irq() to prevent that.
A single bugfix for the PASID management code, which freed the PASID too early. The PASID needs to be tied to the mm lifetime, not to the address space lifetime.
- A fix to disable PCI/MSI[-X] masking for XEN_HVM guests as that is solely controlled by the hypervisor - A build fix to make the function prototype (__warn()) as visible as the definition itself - A bunch of objtool annotation fixes which have accumulated over time - An ORC unwinder fix to handle bad input gracefully - Well, we thought the microcode gets loaded in time in order to restore the microcode-emulated MSRs but we thought wrong. So there's a fix for that to have the ordering done properly - Add new Intel model numbers - A spelling fix
- A bunch of objtool fixes to improve unwinding, sibling call detection, fallthrough detection and relocation handling of weak symbols when the toolchain strips section symbols
- Fix locking when accessing device MSI descriptors
