#     powerpc: dump kernel log before carrying out fadump or kdump
#     
#     Since commit 4388c9b3a6ee ("powerpc: Do not send system reset request
#     through the oops path"), pstore dmesg file is not updated when dump is
#     triggered from HMC. This commit modified system reset (sreset) handler
#     to invoke fadump or kdump (if configured), without pushing dmesg to
#     pstore. This leaves pstore to have old dmesg data which won't be much
#     of a help if kdump fails to capture the dump. This patch fixes that by
#     calling kmsg_dump() before heading to fadump ot kdump.
#
