Subject: sparc: simplify syscall_get_arch()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=75dddcbd9651eec29708f91149e405cd42cf68d7;p=linux-beck.git

sparc: simplify syscall_get_arch()

Include linux/thread_info.h so we can use is_32_bit_task() cleanly.
Then just simplify syscall_get_arch() since is_32_bit_task() works for
all configuration options.
