[Xen-devel] [PATCH] lzma: fix hypervisor build

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Remove local definition of MIN and instead include the kernel.h header
for the hypervisor build. Fixes the following error on the tools build:

In file included from xc_dom_decompress_unsafe_lzma.c:8:0:
../../xen/common/unlzma.c:33:0: error: "MIN" redefined [-Werror]
 #define MIN(a, b) (((a) < (b)) ? (a) : (b))
 ^
In file included from xc_private.h:43:0,
                 from xg_private.h:29,
                 from xc_dom_decompress_unsafe_lzma.c:5:
/home/osstest/build.125458.build-amd64/xen/stubdom/libxc-x86_64/../../tools/include/xen-tools/libs.h:21:0:
 note: this is the location of the previous definition
 #define MIN(x, y) ((x) < (y) ? (x) : (y))
 ^
