[PATCH 00/13] x86/paravirt: Make pv ops code generation more closely match reality
This changes the pv ops code generation to more closely match reality.
For example, instead of:
callq *0xffffffff81e3a400 (pv_irq_ops.save_fl)
vmlinux will now show:
pushfq
pop %rax
nop
nop
nop
nop
nop
which is what the runtime version of the code will show in most cases.
This idea was suggested by Andy Lutomirski.
The benefits are:
- For the most common runtime cases
