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

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.
