[Xen-devel] Backport requests to stable for Xen ARM

[Julien Grall <julien.grall@xxxxxxx>]

Hello,

It has been a while without any ARM backport request. Ian Campbell
used to keep a list of backport fixes for Xen ARM and apply them
to stable. Now that he left, I am not sure who will do it.

I would be fine to keep the list of patches, although I am not
a committer. Stefano do you plan to apply the backport?

I would like to request backport for the following patches:

xen/arm: traps: Correctly interpret the content of the register HPFAR_EL2 
commit c0516182ff86d77375c35517036535c0df61c7e1 and depends on commit 
edd429c9cc2af99df9dda10002cc59011edf0cac
up to Xen 4.4

xen/arm: Force broadcast of TLB and instruction cache maintenance instructions
commit e2faa286faa36da36ee14f6bc973043013001724
up to Xen 4.4

arm: Fix asynchronous aborts (SError exceptions) due to bogus PTE
commit 0ebb6832f043ecfc6a3dcab8a7ba5c4070901ab7
up to Xen 4.5

xen/arm: ignore writes to GICD_ICACTIVER ... GICD_ICACTIVERN
commit 68778eeaa3babedba9677400f63f1e7564bba561
up to Xen 4.6

xen/arm64: ensure that the correct SP is used for exceptions
commit b7e5aee0a36487d6205c1633add25fd430d3b6d7

Note that whilst it would be nice to get
"xen/arm64: correctly emulate the {w, x}zr registers" backported,
the patch depends on lots of IO emulation rework. So I have
not included it in the backport request.

Regards,
