Please unblock grub2 2.02+dfsg1-18. #927888 is RC; #927269 possibly
should be RC since it entirely breaks one of GRUB's platforms; and
#919915 causes upgrade trouble if you run into it.
(Apologies for the .gitignore/.bzrignore noise, which is the result of
switching to using dgit as of this upload. But it's easy enough to, er,
ignore.)
I don't remember if it needs to be done separately, but I've included
the -signed versions in this unblock request just in case, since they
should all go in together.

+Subject: arm: Align section alignment with manual relocation offset code
+
+The arm relocation code has a manual special case for EFI binaries to
+add the natural alignment to its own relocation awareness.
+
+Since commit a51f953f4ee87 ("mkimage: Align efi sections on 4k
+boundary") we changed that alignment from 0x400 to 0x1000 bytes. Reflect
+the change in that branch that we forgot as well.
+
+This fixes running 32bit arm grub efi binaries for me again.

+Subject: arm: Move trampolines into code section
+
+When creating T32->A32 transition jumps, the relocation code in grub
+will generate trampolines. These trampolines live in the .data section
+of our PE binary which means they are not marked as executable.
+
+This misbehavior was unmasked by commit a51f953f4ee87 ("mkimage: Align
+efi sections on 4k boundary") which made the X/NX boundary more obvious
+because everything became page aligned.
+
+To put things into proper order, let's move the arm trampolines into the
+.text section instead. That way everyone knows they are executable.
