From 6ea13cdb3f33da45d7a8042d85ad87e2a18fc946 Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Thu, 1 Jun 2017 10:06:38 -0400 Subject: [PATCH 183/249] Use grub_efi_...() memory helpers where reasonable. This uses grub_efi_allocate_pool(), grub_efi_free_pool(), and grub_efi_free_pages() instead of open-coded efi_call_N() calls, so we get more reasonable type checking.
