With the previous patch "mmc: block: mmcblkN: use slot index instead of
dynamic name index" name_idx is not needed any more.

On embedded devices, often there is a combination of removable mmc
devices (e.g. MMC/SD cards) and hard wired ones (e.g. eMMC).
Depending on the hardware configuration, the 'mmcblkN' node might
change if the removable device is available or not at boot time.
E.g. if the removable device is attache

Hi all,
this patch series implements Xen support for ARMv7 with virtualization
extensions. It allows a Linux guest to boot as dom0 and
as domU on Xen on ARM. PV console, disk and network frontends and
backends are all working correctly.
It has been tested on a Versatile Express Cortex A15 emulato
bind_evtchn_to_irqhandler can legitimately return 0 (irq 0): it is not
an error.
If Linux is running as an HVM domain and is running as Dom0, use
xenstored_local_init to initialize the xenstore page and event channel.
Changes in v2:
- refactor xenbus_init.

We need them because _set_bit etc are not SMP safe if !CONFIG_SMP. But

We need a register to pass the hypercall number because we might not

Reset the IRQ_NOAUTOEN and IRQ_NOREQUEST flags that are enabled by
default on ARM. If IRQ_NOAUTOEN is set, __setup_irq doesn't call
irq_startup, that is responsible for calling irq_unmask at startup time.
As a result event channels remain masked.

This is a simple, hacky implementation of xen_remap_domain_mfn_range,

It should use same interface as hybrid x86.
