From: Bernhard Walle Subject: [PATCH] Add quirk for SLES9 LKCD header Upstream: never On SLES9, we have a different header on IA64: SLES 10: typedef struct __dump_header_asm { uint64_t dha_magic_number; uint32_t dha_version; uint32_t dha_header_size; uint64_t dha_pt_regs; struct pt_regs dha_regs; uint64_t dha_rnat; uint64_t dha_pfs; uint64_t dha_bspstore; uint32_t dha_smp_num_cpus; uint32_t dha_dumping_cpu; struct pt_regs dha_smp_regs[NR_CPUS]; uint64_t dha_smp_current_task[NR_CPUS]; uint64_t dha_stack[NR_CPUS]; uint64_t dha_stack_ptr[NR_CPUS]; uint64_t dha_kernel_addr; } __attribute__((packed)) dump_header_asm_t; SLES 9: typedef struct __dump_header_asm { uint64_t dha_magic_number; uint32_t dha_version; uint32_t dha_header_size; uint64_t dha_kernel_addr; uint64_t dha_pt_regs; struct pt_regs dha_regs; uint64_t dha_rnat; uint64_t dha_pfs; uint64_t dha_bspstore; uint32_t dha_smp_num_cpus; uint32_t dha_dumping_cpu; struct pt_regs dha_smp_regs[NR_CPUS]; uint64_t dha_smp_current_task[NR_CPUS]; uint64_t dha_stack[NR_CPUS]; uint64_t dha_stack_ptr[NR_CPUS]; } __attribute__((packed)) dump_header_asm_t; That patch tries to guess if it's a SLES 9 or a SLES 10 header at runtime.
