Subject: [PATCH] Arm: check for the PE magic for the compiled arch
|
|
|
|
In "arm64: Fix EFI loader kernel image allocation", Ben fixed the kernel
|
|
alignment to match the alignment given in the PE header. In doing so, a
|
|
check for valid PE magic was added, which was hard-coded to the value
|
|
seen on Aarch64 (GRUB_PE32_PE64_MAGIC).
|
|
|
|
Unfortunately, this code is shared between 64-bit and 32-bit, and so
|
|
that value broke 32-bit Arm systems.
|
|
|
|
This patch adds a constant definition for GRUB_PE32_PEXX_MAGIC, which is
|
|
either GRUB_PE32_PE64_MAGIC or GRUB_PE32_PE32_MAGIC, depending on which
|
|
platform is being built, and uses it in the header magic check.
|
|
|
|
Resolves: rhbz#2000756
