Hi all,
Building Linus' tree, today's linux-next build (htmldocs) produced
these warnings:
Documentation/virt/kvm/api.rst:4537: WARNING: Unexpected indentation.
Documentation/virt/kvm/api.rst:4539: WARNING: Block quote ends without a blank line; unexpected unindent.
Introduced by commit
c21d54f0307f ("KVM: x86: hyper-v: allow KVM_GET_SUPPORTED_HV_CPUID as a system ioctl")
These have been around for some time.

Cheers,

I am still seeing the above and have noticed another one:
Documentation/virt/kvm/api.rst:5002: WARNING: Unexpected indentation.
Documentation/virt/kvm/api.rst:5002: WARNING: Inline emphasis start-string without end-string.
Introduced by commit
c32b1b896d2a ("KVM: X86: Add the Document for KVM_CAP_X86_BUS_LOCK_EXIT")
(Not new, but newly reported - or maybe just changed line number)

My bad.
I wonder how I don't see them. I very much tested a config with both
SMP and PROC_FS, and those obviously correct warnings do not show up
for me on either arm64 or x86-64.
Does anybody have a clue-bat: what makes only the powerpc build show
this valid warning?

The obvious fix to just remove the stale static variables has been pushed out.
And it turns out I see the failure too, if I use clang.
Interestingly, clang did *not* complain about the
static DEFINE_MUTEX(profile_flip_mutex);
only about the static DEFINE_PER_CPU() cases.
So it looks like having an initializer ends up suppressing the
message, probably due to various historical usage patterns (eg things
like
static char *rcsid="$Id...";
which is a common traditional pattern).
I have the same gcc version on both arm64 and x86-64, so I guess it
could also be some gcc version dependency that caused me to not see
it.

I also did not understand why my arm and x86_64 builds did not get
these warnings, but my i386 defconig build (that I only do at the end
of my merging) actually failed, so I remerged your tree with the fix in
it.
