[Xen-devel] [PATCH v5 01/16] arm64: s/ALTERNATIVE/HAS_ALTERNATIVE/

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

No functional change. We resist the temptation to move
the entries in the Kconfig file to be more in alphabetical
order as the "arm/x86/common: Add HAS_[ALTERNATIVE|EX_TABLE]"
will move one of the entries to common file.

v4: New submission.
    [Forgot to post as part of the patch series, included as
    inline reply to one of the patches].
v5: Don't sort the HAS_ALTERNATIVE and HAS_GICV3 in alphabetical
    order.
