Björn Töpel 3f7023171d riscv/purgatory: 4B align purgatory_start ... When a crashkernel is launched on RISC-V, the entry to purgatory is done by trapping via the stvec CSR. From riscv_kexec_norelocate(): | ... | /* | * Switch to physical addressing | * This will also trigger a jump to CSR_STVEC | * which in this case is the address of the new | * kernel. | */ | csrw CSR_STVEC, a2 | csrw CSR_SATP, zero stvec requires that the address is 4B aligned, which was not the case, e.g.: | Loaded purgatory at 0xffffc000 | kexec_file: kexec_file_load: type:1, start:0xffffd232 head:0x4 flags:0x6 The address 0xffffd232 not 4B aligned. Correct by adding proper function alignment. With this change, crashkernels loaded with kexec-file will be able to properly enter the purgatory.
