x86: trivial: remove unnecessary get_order in free_thread_info
PATCH 1/1 x86: trivial: remove unnecessary get_order in free_thread_info
From: Zhao Jin <[email protected]>
Because THREAD_SIZE is defined as PAGE_SIZE << THREAD_ORDER on x86, the call of get_order(THREAD_SIZE) can be replaced with THREAD_ORDER.
