[Qemu-devel] [PATCH v2 0/3] migration: usefaultfd cleanups

[Michael S. Tsirkin]

We normally do not need to bother with ifdefs around
specific system-calls. userfaultfd turns out to be
different because our unistd import into linux-headers
is incomplete: it's missing asm-generic bits,
some arm and mips headers.

Fix it up, and drop ifdefs for usefaultfd.

Tested on x86 only.

Pls consider merging this through the migration tree.

[Qemu-devel] [PATCH v2 2/3] linux-headers: add asm-generic/unistd.h

[Michael S. Tsirkin]

ARM64 and MIPS depend on asm-generic/unistd.h for syscall numbers.
This adds asm-generic/unistd.h and it's dependencies.

[Qemu-devel] [PATCH v2 3/3] postcopy: drop unnecessary conditions

[Michael S. Tsirkin]

We have our own copy of unistd so there is no
need to check for symbols present there.

I just sent a mail in the other thread about this, but we
only have our own copy of unistd if the host architecture
supports KVM. If it doesn't then we're going to be using
the system's copy of the includes...

We don't need to blacklist ia64 here, beacues it doesn't have the kvm
headers in the kernel any more, so it is already being skipped because
of the condition at the top of the loop that ignores any arch which
doesn't have a kvm.h.

For MIPS, KVM is supposed to be properly supported these days, right?
That sounds like we should not be blacklisting them either, but instead
sorting out whatever issues it was that made us exclude them.

Hmm good point.

I guess I should leave postcopy alone then, and just update
the headers?

That can go through my tree ...

OK.

I agree but I'd rather someone else looked at this.

Self-Nack

pls ignore - we do not have unistd.h on all systems unfortunately.

Will send v3 without this patch and with more tweaks.
