Subject: [GIT PULL] Floppy cleanups for next

Hi Jens,

The following changes since commit 2ef96a5bb12be62ef75b5828c0aab838ebb29cb8:

  Linux 5.7-rc5 (2020-05-10 15:16:58 -0700)

are available in the Git repository at:

  https://github.com/evdenis/linux-floppy tags/floppy-for-5.8

Please pull

----------------------------------------------------------------
Floppy patches for 5.8

Cleanups:
  - symbolic register names for x86,sparc64,sparc32,powerpc,parisc,m68k
  - split of local/global variables for drive,fdc
  - UBSAN warning suppress in setup_rw_floppy()

Changes were compile tested on arm, sparc64, powerpc, m68k. Many patches
introduce no binary changes by using defines instead of magic numbers.
The patches were also tested with syzkaller and simple write/read/format
tests on real hardware.
