From 15670bfe19905b1dcbb63137f40d718b59d84479 Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Sat, 28 Oct 2017 09:30:38 +0800 Subject: [PATCH] x86/mm/64: Rename the register_page_bootmem_memmap() 'size' parameter to 'nr_pages' register_page_bootmem_memmap()'s 3rd 'size' parameter is named in a somewhat misleading fashion - rename it to 'nr_pages' which makes the units of it much clearer. Meanwhile rename the existing local variable 'nr_pages' to 'nr_pmd_pages', a more expressive name, to avoid conflict with new function parameter 'nr_pages'. (Also clean up the unnecessary parentheses in which get_order() is called.)
