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
