x86/entry: Fix register corruption in compat syscall (2022-05-19 23:46:08 +0200)

----------------------------------------------------------------
- A bunch of changes towards streamlining low level asm helpers' calling
conventions so that former can be converted to C eventually

- Simplify PUSH_AND_CLEAR_REGS so that it can be used at the system call
entry paths instead of having opencoded, slightly different variants of it
everywhere

- Misc other fixes

x86/mm: Simplify RESERVE_BRK()
