src/sys/arch/amd64/include: frameasm.h
Log Message:
Declare INTRFASTEXIT as a function, so that there is only one iretq in the
kernel. Then, check %rip against the address of this iretq instead of
disassembling (%rip) - which could fault again, or point at some random
address which happens to contain the iretq opcode. The same is true for gs
below, but I'll fix that in another commit.
