From 3eb6f1f9e6364d5eca1ddf3c9e963c5916069190 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Wed, 11 Jul 2018 14:56:36 +0100 Subject: [PATCH] arm64: consistently use unsigned long for thread flags In do_notify_resume, we manipulate thread_flags as a 32-bit unsigned int, whereas thread_info::flags is a 64-bit unsigned long, and elsewhere (e.g. in the entry assembly) we manipulate the flags as a 64-bit quantity. For consistency, and to avoid problems if we end up with more than 32 flags, let's make do_notify_resume take the flags as a 64-bit unsigned long.
