Subject: sparc: ptrace: Use USER_REGSET_NOTE_TYPE() to specify regset note names
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c9d4cb25e94e0c2a5ff3e3cdc7da624d42c3aa33;p=thirdparty%2Fkernel%2Flinux.git

sparc: ptrace: Use USER_REGSET_NOTE_TYPE() to specify regset note names

Instead of having the core code guess the note name for each regset,
use USER_REGSET_NOTE_TYPE() to pick the correct name from elf.h.
