[Xen-devel] [PATCH] xen: random: Add missing include xen/cache.h

[Julien Grall <julien.grall@xxxxxxxxxx>]

The commit f6c9698 " x86: allow reading MSR_IA32_TSC with XENPF_resource_op"
introduced a built regression on ARM platform.

random.c:8:28: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before 
âboot_randomâ
 unsigned int __read_mostly boot_random;
                            ^
The define __read_mostly is defined in asm/cache.h which is included by
other headers on x86 but not on ARM. Include xen/cache.h to fix the
build.
