Subject: [GIT] Sparc
1) Kill off support for sun4c and Cypress sun4m chips.
And as a result we were able to also kill off that ugly
btfixup thing that required multi-stage links of the final
vmlinux image in the Kbuild system. This should make the
kbuild maintainers really happy.
Thanks a lot to Sam Ravnborg for his tireless efforts to
get this going.
2) Convert sparc64 to nobootmem. I suspect now with sparc32
being a lot cleaner, it should be able to fall in line and
modernize in this area too.
3) Make sparc32 use generic clockevents, from Tkhai Kirill.
There is going to be a merge conflict between the commit in the
net-next tree that adds the Sparc BPF JIT, and the one in here which
adds arch/sparc/Kbuild. It should be quite easy to resolve.
Please pull, thanks a lot!
