  x86/apic: Fix kernel panic when booting with intremap=off and x2apic_phys (2023-06-19 20:59:40 +0200)

----------------------------------------------------------------
- Do not use set_pgd() when updating the KASLR trampoline pgd entry
  because that updates the user PGD too on KPTI builds, resulting in
  memory corruption

- Prevent a panic in the IO-APIC setup code due to conflicting command
  line parameters
