RISC-V Fixes for 5.6-rc4

This tag contains a handful of RISC-V related fixes that I've collected and
would like to target for 5.6-rc4:

* A fix to set up the PMPs on boot, which allows the kernel to access memory on
  systems that don't set up permissive PMPs before getting to Linux.  This only
  effects machine-mode kernels, which currently means only NOMMU kernels.
* A fix to avoid enabling supervisor-mode interrupts when running in
  machine-mode, also only for NOMMU kernels.
* A pair of fixes to our KASAN support to avoid corrupting memory.
* A gitignore fix.

This boots on QEMU's virt board for me.

What about this patch https://patchwork.kernel.org/patch/11395273/ from 
Vincent that fixes module loading problems described here:

https://lore.kernel.org/linux-riscv/d868acf5-7242-93dc-0051-f97e64dc4387@ghiti.fr/T/

Do you consider it for 5.6 ?

Thanks,

Alex

I haven't gotten to them yet, but at a glance it's probably a big enough change
that it should should go in during a merge window.  The module loading stuff is
a bit of a rats nest because it never really got finished, so I want to make
sure things get sufficient testing over there.

I'll try to take a look, though -- it's only ~1K messages deep in my inbox, so
there's hope :).
