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

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
