Rebased on for-5.8/drivers branch. The following changes since commit 92decf118f1da4c866515f80387f9cf4d48611d6: nvme: define constants for identification values (2020-05-09 16:18:36 -0600) are available in the Git repository at: https://github.com/evdenis/linux-floppy tags/floppy-for-5.8 for you to fetch changes up to 0836275df4db20daf040fff5d9a1da89c4c08a85: floppy: suppress UBSAN warning in setup_rw_floppy() (2020-05-12 19:34:57 +0300) ---------------------------------------------------------------- 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.
