[Xen-devel] [PATCH] stubdom/libxc: Fix build of unsafe decompressors

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

c/s b683d68c386 changed the packing attribute on struct lzma_header.  libxc
includes the Xen decompression .c, (for stubdoms only) but without access to
the Xen header files.

Fix in the main header file for any potential change in Xen, rather than in
for just lzma alone.
