Subject: tile: Remove signal translation and exec_domain
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=89f191b31ceeb8e79c46815533b7d96c15e83720;p=linux-beck.git

tile: Remove signal translation and exec_domain

As execution domain support is gone we can remove
signal translation from the signal code and remove
exec_domain from thread_info.
