Merge branch 'crashkernel-cma' into kexec-next (2026-08-04 10:48:21 +0300)
----------------------------------------------------------------
kexec: updates for v7.3-rc1
* Deduplicate crash memory allocation and the exclusion of reserved crash
kernel regions from architecture specific code into a generic
crash_prepare_headers() and enable crashkernel CMA reservation on arm64 and
riscv reservation on arm64 and riscv.
* Skip purgatory checksum verification when the kexec segments cannot be
corrupted by DMA, which saves about 250ms on kexec.
* Replace __ASSEMBLY__ with the compiler provided __ASSEMBLER__ in
include/linux/kexec.h.
* Fix a keyring refcount imbalance in the kdump kernel's dm-crypt key restore
path, which over-dropped the user keyring reference when more than one key
was restored.
