stagingL vt6656: implement fall back rates reporting.
The driver reports the rate tried in struct vnt_interrupt_data tsr* variables
which is available in INTnsProcessData via interrupt urb context.
Instead of closing apTD tx context in s_nsBulkOutIoCompleteWrite by setting
in_use to false. Keep the context open and allow vnt_int_report_rate to
close it.
If the tx_retry value is correct it will report back the sucessful RATE tried.
struct vnt_usb_send_context add pkt_no which is index of apTD
staging: rtl8723au: Sanitize USB read/write functions
The original Realtek provided functions suffered badly from clutter to
accommodate broken operating systems. Lets try this lean and clean
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().

binder_ioctl() is quite huge and checkpatch dirty - mostly because of
the amount of code for the BINDER_WRITE_READ and BINDER_SET_CONTEXT_MGR.
Moved that code into the new binder_ioctl_write_read() and
binder_ioctl_set_ctx_mgr()

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.

- Marvell fixes for PCIe on SMP and a big-endian fix.

bcm_defconfig again.
... and a couple of MAINTAINERS updates, one to claim new Keystone
drivers that have been merged, and one to merge MXS and i.MX (both
Freescale platforms).
The largest diffs come from the hwmod code for omap5 and the re-add of
the restart code on sunxi. The hwmod stuff is quite late at this
point but it slipped through cracks repeatedly while coming up the
maintainer chain and only affects the one SoC so risk is low"
