alpha: drop pre-EV56 support (2024-05-06 12:05:00 +0200)
----------------------------------------------------------------
alpha: cleanups and build fixes
I had investigated dropping support for alpha EV5 and earlier a while
ago after noticing that this is the only supported CPU family
in the kernel without native byte access and that Debian has already
dropped support for this generation last year [1] in order to
improve performance for the newer machines.
This topic came up again when Paul E. McKenney noticed that
parts of the RCU code already rely on byte access and do not
work on alpha EV5 reliably, so we decided on using my series to
avoid the problem entirely.
Al Viro did another series for alpha to address all the known build
issues. I rebased his patches without any further changes and included
it as a baseline for my work here to avoid conflicts and allow
backporting the fixes to stable kernels for the now removed hardware
support as well.
----------------------------------------------------------------
Al Viro (9):
alpha: sort scr_mem{cpy,move}w() out
alpha: fix modversions for strcpy() et.al.
alpha: add clone3() support
alpha: don't make functions public without a reason
alpha: sys_sio: fix misspelled ifdefs
alpha: missing includes
alpha: core_lca: take the unused functions out
alpha: jensen, t2 - make __EXTERN_INLINE same as for the rest
alpha: trim the unused stuff from asm-offsets.c
Arnd Bergmann (5):
alpha: remove DECpc AXP150 (Jensen) support
alpha: sable: remove early machine support
alpha: remove LCA and APECS based machines
alpha: cabriolet: remove EV5 CPU support
alpha: drop pre-EV56 support
