Andrew Morton 4150d3f549 revert "highmem: catch illegal nesting" ... Revert commit 656dad312f Author: Ingo Molnar <mingo@elte.hu> Date: Sat Feb 10 01:46:36 2007 -0800 [PATCH] highmem: catch illegal nesting Catch illegally nested kmap_atomic()s even if the page that is mapped by the 'inner' instance is from lowmem. This avoids spuriously zapped kmap-atomic ptes and turns hard to find crashes into clear asserts at the bug site. Problem is, a get_zeroed_page(GFP_KERNEL) from interrupt context will trigger this check if non-irq code on this CPU holds a KM_USER0 mapping. But that get_zeroed_page() will never be altering the kmap slot anyway due to the GFP_KERNEL.
