Subject: [RFC PATCH 01/12] powerpc/tm: Remove struct thread_info param from tm_reclaim_thread()

From: Cyril Bur <[email-masked]>
Date: Tue, 20 Feb 2018 11:22:30 +1100

tm_reclaim_thread() doesn't use the parameter anymore, both callers have
to bother getting it as they have no need for a struct thread_info
either.

It was previously used but became unused in dc3106690b20 ("powerpc: tm:
Always use fp_state and vr_state to store live registers")

Just remove it and adjust the callers.
