Hey all,
Couple fixes here for most of what's left of the {sparse,} warnings in
arch/riscv that are still in need of patches. Ben has sent patches
for the VDSO issue already (although they seem to need rework).
VDSO aside, With this patchset applied, we are left with:
- cpuinfo_ops missing prototype: this likely needs to go into an
asm-generic header & I'll send a separate patch for that.
- Complaints about an error in mm/init.c:
"error inarch/riscv/mm/init.c:819:2: error: "setup_vm() is <trunc>
I think this can be ignored.
- 600+ -Woverride-init warnings for syscall table setup where
overriding seems to be the whole point of the macro.
- Warnings about imported kvm core code.
- Flexible array member warnings that look like common KVM code
patterns
- An unexpected unlock in kvm_riscv_check_vcpu_requests that was added
intentionally:

Is it worth looking into whether that's a false positive or not?
Thanks,
Conor.

These generally look good to me. Anup handles the KVM bits so I'll let
him chime in there, but

on all of them.
Happy to do some sort of shared tag thing, but it looks like these are
all independent enough that it'd be easier to just split them up. I've
put the non-KVM bits over at palmer/riscv-variable_fixes_without_kvm, if
you guys are all OK splitting this up then I'll go take those onto
riscv/fixes. I'll wait a bit for folks to get a chance to look, so it
won't be for tomorrow morning.
Thanks!
