-Subject: x86/efistub: Clear decompressor BSS in native EFI entrypoint
-Origin: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit?id=9274ec2003042bf0ed847cb80ffcfab543a0a33a

-[ Upstream commit b3810c5a2cc4a6665f7a65bed5393c75ce3f3aa2 ]
-
-The EFI stub on x86 no longer invokes the decompressor as a subsequent
-boot stage, but calls into the decompression code directly while running
-in the context of the EFI boot services.
-
-This means that when using the native EFI entrypoint (as opposed to the
-EFI handover protocol, which clears BSS explicitly), the firmware PE
-image loader is being relied upon to ensure that BSS is zeroed before
-the EFI stub is entered from the firmware.
-
-As Radek's report proves, this is a bad idea. Not all loaders do this
-correctly, which means some global variables that should be statically
-initialized to 0x0 may have junk in them.
-
-So clear BSS explicitly when entering via efi_pe_entry(). Note that
-zeroing BSS from C code is not generally safe, but in this case, the
-following assignment and dereference of a global pointer variable
-ensures that the memset() cannot be deferred or reordered.
