[PATCH 0/2] Make badr macro compatible with newer GAS versions

From: Ard Biesheuvel
Date: Tue Jun 19 2018 - 15:27:50 EST


Work around the mindless and backward incompatible change in GAS that
prevents us from using a simple addition to set the Thumb bit in local
symbol references taken using 'adr' instructions (#2)

As a preparatory step, remove badr occurrences in ARM code sequences
contained in Thumb2 kernels.

Ard Biesheuvel (2):
ARM: avoid badr macro for switching to Thumb-2 mode
ARM: assembler: prevent ADR from setting the Thumb bit twice
