Hi people!
Just a few BPF related backports from master to the gcc-10 branch.
I left the changelog entry dates of the original commits untouched,
and added `(cherry-pick from commit XXX)' lines to the commit
messages. Hope that is ok... please let me know otherwise! :)
Salud!
Jose E. Marchesi (4):
bpf: add support for the -mxbpf option
bpf: do not save/restore callee-saved registers in function
prolog/epilog
bpf: more flexible support for kernel helpers
bpf: remove trailing whitespaces from source files
