*	xen/arm: Fix compile errors when drivers are compiled as modules (export more).	Stefano Stabellini	2012-11-09
\| \| \| \| \| \| \| \| \| \| \| \|	The commit 911dec0db4de6ccc544178a8ddaf9cec0a11d533 "xen/arm: Fix compile errors when drivers are compiled as modules." exports the neccessary functions. But to guard ourselves against out-of-tree modules and future drivers hitting this, lets export all of the relevant hypercalls.

*	xen/arm: Fix compile errors when drivers are compiled as modules.	Konrad Rzeszutek Wilk	2012-11-07
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	We end up with: ERROR: "HYPERVISOR_event_channel_op" [drivers/xen/xen-gntdev.ko] undefined! ERROR: "privcmd_call" [drivers/xen/xen-privcmd.ko] undefined! ERROR: "HYPERVISOR_grant_table_op" [drivers/net/xen-netback/xen-netback.ko] undefined! and this patch exports said function (which is implemented in hypercall.S).

*	xen/arm: receive Xen events on ARM	Stefano Stabellini	2012-09-14
\| \| \| \| \| \| \| \| \| \|	Compile events.c on ARM. Parse, map and enable the IRQ to get event notifications from the device tree (node "/xen"). Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
*	xen/arm: initialize grant_table on ARM	Stefano Stabellini	2012-09-13
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Initialize the grant table mapping at the address specified at index 0 in the DT under the /xen node. After the grant table is initialized, call xenbus_probe (if not dom0). Changes in v2: - introduce GRANT_TABLE_PHYSADDR; - remove unneeded initialization of boot_max_nr_grant_frames.

*	xen/arm: get privilege status	Stefano Stabellini	2012-08-08
\| \| \| \| \| \| \| \| \| \|	Use Xen features to figure out if we are privileged. XENFEAT_dom0 was introduced by 23735 in xen-unstable.hg. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
*	xen/arm: Xen detection and shared_info page mapping	Stefano Stabellini	2012-09-14
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Check for a node in the device tree compatible with "xen,xen", if it is present set xen_domain_type to XEN_HVM_DOMAIN and continue initialization. Map the real shared info page using XENMEM_add_to_physmap with XENMAPSPACE_shared_info. Changes in v4: - simpler parsing of Xen version in the compatible DT node. Changes in v3: - use the "xen,xen" notation rather than "arm,xen"; - add an additional check on the presence of the Xen version. Changes in v2: - replace pr_info with pr_debug.

*	arm: initial Xen support	Stefano Stabellini	2012-09-14
	- Basic hypervisor.h and interface.h definitions. - Skeleton enlighten.c, set xen_start_info to an empty struct. - Make xen_initial_domain dependent on the SIF_PRIVILIGED_BIT. The new code only compiles when CONFIG_XEN is set, that is going to be added to arch/arm/Kconfig in patch #11 "xen/arm: introduce CONFIG_XEN on ARM". Changes in v3: - improve comments.
