Subject: [PATCH 0/2] x86/fpu: Fix FPU context sizing boot regression, introduce dynamic task_struct
Date: Fri, 17 Jul 2015 12:28:10 +0200 [thread overview]
Message-ID: <1437128892-9831-1-git-send-email-mingo@kernel.org> (raw)
This series builds on top of Dave Hansen's initial patch that introduced
dynamic task_struct sizing.
The second patch improves the dynamic allocation to not impact non-x86 architectures,
and to make it a bit faster on x86.
( I kept the structure layout build checks in x86 code for the time being,
because some of the cross-builds failed with the generic check and I didn't
want to introduce a bigger cross section for any failures. And it's not like
we'll apply generic sched.h changes without testing x86. )
Thanks,
Ingo
