version instead.

v2: Do not use the stack for data passed to usb_control_msg(). This
    requires reintroducing the mutex used in the old function. In
    addition, get rid of the no longer used 'usb_vendor_req_buf'.
    Note that rtl8723au_writeN() remains unlocked, so it can be used
    for bulk block transfers without having to retake the mutex for
    every write().

staging: binder: add vm_fault handler

An issue was observed when a userspace task exits.
The page which hits error here is the zero page.
In binder mmap, the whole of vma is not mapped.
On a task crash, when debuggerd reads the binder regions,
the unmapped areas fall to do_anonymous_page in handle_pte_fault,
due to the absence of a vm_fault handler. This results in
zero page being mapped. Later in zap_pte_range, vm_normal_page
returns zero page in the case of VM_MIXEDMAP and it results in the
error.

ARM: sunxi: Reintroduce the restart code for A10/A20 SoCs

the sun4i, sun5i and sun7i families.

Fixes for omaps for issues discovered during the merge window and

- Fix SoC detection for DRA722
- Fix CPU OPP table for omap5
- Fix legacy mux parser bug if requested muxname is a prefix of

- Add missing phy_sel for am43x-epos-evm
- Drop unused gic_init_irq() that is no longer needed

And the enabling of features that had driver dependencies are:

- Change dra7 to use Audio Tracking Logic clock instead of a fixed
  clock now that the clock driver for it has been merged

- Enable off idle configuration for selected omaps as all the kernel
  dependencies for device tree based booting are finally merged as
  this is needed to get the automated PM tests working finally with
  device tree based booting

- Add hwmod entry for ocp2scp3 for omap5 to get sata working as
  all the driver dependencies are now in the kernel and this patch
  fell through the cracks during the merge window

arm64: fix el2_setup check of CurrentEL

The CurrentEL system register reports the Current Exception Level
of the CPU. It doesn't say anything about the stack handling, and
yet we compare it to PSR_MODE_EL2t and PSR_MODE_EL2h.

It works by chance because PSR_MODE_EL2t happens to match the right
bits, but that's otherwise a very bad idea. Just check for the EL
value instead.
