From 7e01b5acd88b3f3108d8c4ce44e3205d67437202 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Thu, 16 Apr 2015 14:47:33 +0200 Subject: [PATCH] kexec: allocate the kexec control page with KEXEC_CONTROL_MEMORY_GFP Introduce KEXEC_CONTROL_MEMORY_GFP to allow the architecture code to override the gfp flags of the allocation for the kexec control page. The loop in kimage_alloc_normal_control_pages allocates pages with GFP_KERNEL until a page is found that happens to have an address smaller than the KEXEC_CONTROL_MEMORY_LIMIT. On systems with a large memory size but a small KEXEC_CONTROL_MEMORY_LIMIT the loop will keep allocating memory until the oom killer steps in.
