Recommendations for backport from unstable to 4.1

Recommendations for backport from unstable to 4.1

[Andrew Cooper]

Hello,

Here are some more recommendations for backports from unstable to 4.1,
based upon the XenServer patch queue.  Patches with a * do not apply
cleanly, and I can provide patches if you wish to backport them.  The
rest should apply cleanly (unless I have missed a dependency on other
patches we have in our queue, which case I apologize)

The following are bugfixes:

* 23101:dd386a4b6595 # x86: fix tboot after c/s 23013:65d26504e843 (ACPI
cleanup)
  23686:7c39a2c0d870 # pygrub: fix solaris kernel issue
  23781:0849b0e59e24 # pm: don't truncate processors' ACPI IDs to 8 bits
  23813:5535d7ce2673 # xen, vtd: Fix device check for devices behind
PCIe-to-PCI bridges
  25162:478bec603d3d # xen: Fix schedule()'s grabbing of the schedule lock
  25487:baa85434d0ec # x86/mm: fix mod_l1_entry() return value when
encountering r/o MMIO page
  25489:cc46bd403bc4 # x86/PCI: fix guest_io_read() when pci_cfg_ok()
denies access


The following are not strictly bugfixes, but I feel they should be
considered:

* 23726:fd97ca086df6 # x86: update Intel CPUID masking code to latest spec
  23731:48f72b389b04 # x86: add change missing in c/s 23726:fd97ca086df6
  24261:64088ba60263 # x86/cpuidle: add Westmere-EX support to hw
residencies reading logic
  24970:33980e36597b # x86/cpuidle: deny access to the I/O port used for
EM_SYSIO
* 25482:34c725807d21 # SVM: fix performance decrease with asid assignment

Andrew,

I applied all the below, except 23101:dd386a4b6595 as the dependent patch
(23013:65d26504e843) is not in OSS 4.1.

Thanks.  Sorry for that patch - it appears it is actually a minimal mix
of 23101 and 23013 to try and make TXTboot work, rather than a strict
backport of 23101.

Is there an eta for 4.1.3 ?

Please revert the backport of 25487:baa85434d0ec - it is wrong in
4.1-testing (where the function still returns a boolean-like value).
