[Xen-devel] [PATCH for-4.9 0/3] Improvements to ERR_PTR() infrastructure

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

One XenServer issue I am looking in to requires improvements to the memory
allocation logic, mostly to avoid losing error information internally.

As a result, I am choosing to make these ERR_PTR() improvements a prerequisite
to avoid accidentally introducing further issues.

Andrew Cooper (3):
  xen/err: Use static inlines and boolean types
  xen/err: Support an optional per-arch slide for the error region
  xen/x86: Use non-canonical pointers for ERR_PTR() errors
