Subject: x32: fix sigtimedwait
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b2ddedcd21f44a5873ee3d6ff6118a2318e01e18;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

x32: fix sigtimedwait

It needs 64bit timespec.  As it is, we end up truncating the timeout
to whole seconds; usually it doesn't matter, but for having all
sub-second timeouts truncated to one jiffy is visibly wrong.
