Hmm. In the meantime, I had pulled the RSEQ time slice extensions
stuff first, so what happened was that these prctl numbers got bumped
up from 79-81 to 80-82.
I note that it looks like linux-next ended up merging things in a
different order, and so instead left the indirect branch status prctls
alone, and instead modified the RSEQ one.
Just letting everybody involved know - maybe this was obvious to
people, and maybe this came as a surprise.
And only very tangentially related: I think the indirect branch
locking could have been just a separate bit from the enable bit. I
don't see why it needed separate prctls for "set status" and "set
lock".
On a similar theme: why is it called "indir_br_lp"? That's a horrible name.
This was supposed to be architecture-neutral, but I get the feeling
that "lp" does not stand for "Long Play" and has nothing to do with
12-inch vinyl records.
I think it probably is shorthand for "lpad", which is RISC-V thing.
Which is complete nonsense for something that is documented to be
architecture-neutral.
So the naming is wrong, and needs to be fixed. So maybe just as well
that the numbers also changed.
In other words: I've pulled this, but I expect this to be fixed asap.
