Pull kexec updates from Mike Rapoport: - 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. * tag 'kexec-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linux: crash_dump: release keyring reference at the correct time kexec: Replace __ASSEMBLY__ with __ASSEMBLER__ in header file kexec_file: skip checksum verification when safe riscv: kexec_file: Add support for crashkernel CMA reservation arm64: kexec_file: Add support for crashkernel CMA reservation powerpc/kexec_file: Use crash_exclude_core_ranges() helper LoongArch: kexec_file: Use crash_prepare_headers() helper to simplify code riscv: kexec_file: Use crash_prepare_headers() helper to simplify code x86/crash: Use crash_prepare_headers() helper to simplify code arm64: kexec_file: Use crash_prepare_headers() helper to simplify code crash: Add crash_prepare_headers() to exclude crash kernel memory powerpc/crash: sort crash memory ranges before preparing elfcorehdr riscv: kexec_file: Fix crashk_low_res not exclude bug
