File 0002-Remove-grub_efi_allocate_pages.patch of Package grub2.20932
From bb4cb6d374625d3716380affda56dc4c20da36db Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko <phcoder@gmail.com> Date: Mon, 7 Aug 2017 18:33:29 +0200 Subject: [PATCH 2/6] Remove grub_efi_allocate_pages. grub_efi_allocate_pages Essentially does 2 unrelated things: * Allocate at fixed address. * Allocate at any address. To switch between 2 different functions it uses address == 0 as magic value which is wrong as 0 is a perfectly valid fixed adress to allocate at. --- grub-core/kern/arm/efi/misc.c | 4 ++-- grub-core/kern/efi/mm.c | 30 ++++++++++++++---------------- grub-core/loader/arm64/fdt.c | 2 +- grub-core/loader/arm64/linux.c | 7 +++---- grub-core/loader/arm64/xen_boot.c | 7 +++---- grub-core/loader/i386/efi/linux.c | 2 +- grub-core/loader/ia64/efi/linux.c | 10 +++++----- include/grub/autoefi.h | 2 +- include/grub/efi/efi.h | 4 +++- 9 files changed, 33 insertions(+), 35 deletions(-) diff --git a/grub-core/kern/arm/efi/misc.c b/grub-core/kern/arm/efi/misc.c index 7cd41842a..c95e8299d 100644 --- a/grub-core/kern/arm/efi/misc.c +++ b/grub-core/kern/arm/efi/misc.c @@ -146,7 +146,7 @@ grub_efi_allocate_loader_memory (grub_uint32_t min_offset, grub_uint32_t size) continue; grub_dprintf("mm", "%s: let's allocate some (0x%x) pages @ 0x%08x...\n", __FUNCTION__, (size >> PAGE_SHIFT), (grub_addr_t) start); - mem = grub_efi_allocate_pages (start, (size >> PAGE_SHIFT) + 1); + mem = grub_efi_allocate_fixed (start, (size >> PAGE_SHIFT) + 1); grub_dprintf("mm", "%s: retval=0x%08x\n", __FUNCTION__, (grub_addr_t) mem); if (!
