Hello, Peter
How is it going?
Do I need to send a new version? How can I cooperate or participate in the details? Do you plan to move the other path of ASM code into C code?
Thanks Lai
PS: And I think [PATCH 12/24] ("x86/traps: Reconstruct pt_regs on task stack directly in fixup_bad_iret()") has nothing related to moving ASM to C is off topic to the patchset. It can be dropped if no one needs it.
