Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini:
"x86:
- Do not register IRQ bypass consumer if posted interrupts not
supported
- Fix missed device interrupt due to non-atomic update of IRR
- Use GFP_KERNEL_ACCOUNT for pid_table in ipiv
- Make VMREAD error path play nice with noinstr
- x86: Acquire SRCU read lock when handling fastpath MSR writes
- Support linking rseq tests statically against glibc 2.35+
- Fix reference count for stats file descriptors
- Detect userspace setting invalid CR0
Non-KVM:
- Remove coccinelle script that has caused multiple confusion
("debugfs, coccinelle: check for obsolete DEFINE_SIMPLE_ATTRIBUTE()
usage", acked by Greg)"
