From: Bernhard Walle <bwalle@suse.de>
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.
