tools headers UAPI: Sync kvm.h headers with the kernel sources

2020-06-09T15:40:04+00:00

To pick the changes in:

  f97f5a56f597 ("x86/kvm/hyper-v: Add support for synthetic debugger interface")
  850448f35aaf ("KVM: nVMX: Fix VMX preemption timer migration")

  acd05785e48c ("kvm: add capability for halt polling")
  3ecad8c2c1ff ("docs: fix broken references for ReST files that moved around")

That do not result in any change in tooling, as the additions are not
being used in any table generator.

This silences these perf build warning:

Merge tag 'docs-5.8' of git://git.lwn.net/linux

2020-06-01T22:45:27+00:00

Pull documentation updates from Jonathan Corbet:
 "A fair amount of stuff this time around, dominated by yet another
  massive set from Mauro toward the completion of the RST conversion. I
  *really* hope we are getting close to the end of this. Meanwhile,
  those patches reach pretty far afield to update document references
  around the tree; there should be no actual code changes there. There
  will be, alas, more of the usual trivial merge conflicts.

  Beyond that we have more translations, improvements to the sphinx
  scripting, a number of additions to the sysctl documentation, and lots
  of fixes"

docs: fix broken references for ReST files that moved around

2020-04-20T21:45:03+00:00

Some broken references happened due to shifting files around
and ReST renames. Those can't be auto-fixed by the script,
so let's fix them manually.

tools headers kvm: Sync linux/kvm.h with the kernel sources

2020-04-14T14:02:52+00:00

To pick up the changes from:

  29b40f105ec8 ("KVM: s390: protvirt: Add initial vm and cpu lifecycle handling")

So far we're ignoring those arch specific ioctls, we need to revisit
this at some time to have arch specific tables, etc:

  $ grep S390 tools/perf/trace/beauty/kvm_ioctl.sh
      egrep -v " ((ARM|PPC|S390)_|[GS]ET_(DEBUGREGS|PIT2|XSAVE|TSC_KHZ)|CREATE_SPAPR_TCE_64)" | \
