Can we also include:

6e395f477fb85 - xen: sched/Credit2: fix bug when moving CPUs between 
two Credit2 cpupools

for 4.10 and 4.11 ?

From a quick check, it' not as easy as cherry-picking/applying the
patch (there's 1 hunk that fails), but it shouldn't be too bad.

And I can provide the backport, if you want me to.

Thanks,
Dario

Hmm, odd - I had certainly meant to (and actually thought I did
already) apply the latter. I'll queue up all of the above (afaict
the former two are relevant only back to 4.9).

In addition, it looks like:

328ca55b7bd4 - x86/shutdown: use ACPI reboot method for Dell PowerEdge R540
7626edeaca97 - x86/hvm/emulate: make sure rep I/O emulation does not
cross GFN boundaries

are general bugfix candidates for backport.

[Xen-devel] Backports to stable trees

2018-09-27 Thread Andrew Cooper
Hello,

Please can the following patches be considered for stable.

18cd4997d26b - x86/efi: move the logic to detect PE build support
93249f7fc17c - x86/efi: split compiler vs linker support

CentOS and RHEL 7.x GCC's are capable of compiling xen.gz with EFI
support, but LD doesn't have i386pep support.  Without a bodge to the
build system (and several downstreams have borrowed by XenServer bodge),
making a EFI-capable xen.gz isn't possible with the default toolchain.

These patches resolve the issue.
