[HIRSUTE][linux-riscv][PATCH 0/3] Disable ftrace of all sbi functions

[Dimitri John Ledkov]

Cherry-pick upstream patches that correctly disable ftrace of all
sbi.c functions, thus preventing spurious failure to boot. One cannot
ftrace functions that are used in ftrace setup.

This has been fixed in v5.12, did not make into 5.11.x-stable which is
no longer stable upstream.

Our previous, incomplete fix, to disable ftrace on just one sbi
function call is thus no longer needed with these cherrypicks and can
be reverted, given that all sbi functions have tracing disabled with
these patches.
