* xen: check required Xen featuresJuergen Gross2021-08-301-0/+18
| | | | | | | | | | | | Linux kernel is not supported to run on Xen versions older than 4.0. Add tests for required Xen features always being present in Xen 4.0 and newer.

* xen: audit usages of module.h ; remove unnecessary instancesPaul Gortmaker2016-03-211-1/+1
| | | | | | | | | | | | | | | | | | | Code that uses no modular facilities whatsoever should not be sourcing module.h at all, since that header drags in a bunch of other headers with it. Similarly, code that is not explicitly using modular facilities like module_init() but only is declaring module_param setup variables should be using moduleparam.h and not the larger module.h file for that. In making this change, we also uncover an implicit use of BUG() in inline fcns within arch/arm/include/asm/xen/hypercall.h so we explicitly source <linux/bug.h> for that file now.

* xen: clean up asm/xen/hypervisor.hJeremy Fitzhardinge2008-12-161-1/+5
| | | | | | | | | | | Impact: cleanup hypervisor.h had accumulated a lot of crud, including lots of spurious #includes. Clean it all up, and go around fixing up everything else accordingly.

* xen: move features.c from arch/x86/xen/features.c to drivers/xenIsaku Yamahata2008-04-241-0/+29
ia64/xen also uses it too. Move it into common place so that ia64/xen can share the code.
