Subject: alpha: Add syscall_get_return_value()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=15b9e384030cf34de33deed70d670a8dc0fc784a;p=linux.git

alpha: Add syscall_get_return_value()

audit now requires syscall_get_return_value instead of regs_return_value
to retrieve syscall return code . Other architectures that support audit
have already define this function.
