[Xen-devel] [PATCH] tools/libxc: Correct XC_DOM_PAGE_SIZE() to return a long long

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

c/s abdf3c5b "libxc: create p2m list outside of kernel mapping if supported"
introduces a use which Coverity objects to; an int used to mask a uint64_t.

The result needs to be signed to allow ~XC_DOM_PAGE_SIZE() to function
correctly, and long long to function properly in 32bit builds.
