Hello everyone, this is the fifth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See http://marc.info/?l=xen-devel&m=132257857628098&w=2 The first 7 patches affect generic Xen code and are not ARM specific; often they fix real issues, hidden in the default X86 configuration. The following 18 patches introduce ARMv7 with virtualization extensions support: makefiles first, then the asm-arm header files and finally everything else, ordered in a way that should make the patches easier to read. Changes in v5: - fix compilation after rebase; - route interrupt 34 (peripheral timer) to dom0; - GICD_ICFGR ... GICD_ICFGRN return 1; - expand tabs; - keep the diff of arch/arm/lib with Linux's equivalents small; - check the size of the arguments of elf_load_image; Changes in v4: - fix arm build after rebasing on xen-unstable 87c607efbfece009360f615b2bf98959f4ea48e8; - use ABS() in __ldivmod_helper; - return a negative integer in case of errors in elf_load_image. Changes in v3: - introduce clear_guest for x86 and ia64 (I kept ia64 version of clear_user for symmetry but it is not actually used anywhere); - rename the current ARM *_user functions to *_guest; - use raw_clear_guest and raw_copy_to_guest in elf_load_image. Changes in v2: - introduce CONFIG_XENOPROF; - make _srodata and _erodata const char[]; - do not include p2m.h ifdef __ia64__; - remove wrong comment about pfn.h; - introduce HAS_KEXEC and CONFIG_KEXEC; - use long in __do_clear_user; - remove the div64 patch, implement __aeabi_ldivmod and __aeabi_uldivmod instead; - move "arm: makefiles" at the end of the series.
