  s390/boot: Fix KASLR base offset off by __START_KERNEL bytes (2024-08-22 19:24:13 +0200)

----------------------------------------------------------------
s390 updates for 6.11-rc5

- Fix KASLR base offset to account for symbol offsets in the vmlinux
  ELF file, preventing tool breakages like the drgn debugger

- Fix potential memory corruption of physmem_info during kernel physical
  address randomization

- Fix potential memory corruption due to overlap between the relocated
  lowcore and identity mapping by correctly reserving lowcore memory

- Fix performance regression and avoid randomizing identity mapping base
  by default

- Fix unnecessary delay of AP bus binding complete uevent to prevent
  startup lag in KVM guests using AP

----------------------------------------------------------------
Alexander Gordeev (4):
      s390/mm: Prevent lowcore vs identity mapping overlap
      s390/mm: Pin identity mapping base to zero
      s390/boot: Avoid possible physmem_info segment corruption
      s390/boot: Fix KASLR base offset off by __START_KERNEL bytes

Harald Freudenberger (1):
      s390/ap: Refine AP bus bindings complete processing
