Modified Files: src/sys/arch/amd64/amd64: amd64_trap.S locore.S Log Message: On amd64, Xen PV calls syscalls and traps with events enabled. Disable events on entry to be safe. It should have been mostly safe for most cases, but for FPU traps we need to reload the FPU state if we got interrupted at trap entry. Hopefully fixes: panic: kernel diagnostic assertion "curlwp->l_md.md_flags & MDL_FPU_IN_CPU" failed: file "/home/source/ab/HEAD/src/sys/arch/x86/x86/fpu.c", line 524 when running tests.
