MIPS: Check for accesses beyond the end of the PGD.

For some combinations of PAGE_SIZE and vmbits, it is possible to have
userspace access that are beyond what is covered by the PGD, but within
vmbits.  Such an access would cause the TLB refill handler to load garbage
values for PMD and PTE potentially giving userspace access to parts of the
physical address space to which it is not entitled.

In the TLB refill hot path, we add a single dsrl instruction so we can
check if any bits outside of the range covered by the PGD are set.  In
the vmalloc side we then separate the bad case from the normal vmalloc
case and call tlb_do_page_fault_0 if warranted.  This slows us down a

MIPS: Don't vmap things at address zero.

2) vmap mappings for all kernel-space accesses in xkseg.

3) vmap mappings for kernel modules in ksseg (kseg2).

Due to how the TLB refill handlers work, any mapping established in
xkseg or ksseg will also establish a xuseg mapping that should never
be used by the kernel.

dereferences, we need to ensure that nothing is mapped at address
zero.  Since vmap mappings in xkseg are reflected in xuseg, this means
we need to ensure that there are no vmap mappings established at the
start of xkseg.  So we move back VMALLOC_START to avoid establishing

According to the header file, dt3155_io.h, the 50/60 Hz configuration
is controlled by a bit in the I2C CSR2 register (bit 2).  The function

USB: xhci: properly set endpoint context fields for periodic eps.

For periodic endpoints, we must let the xHCI hardware know the maximum
payload an endpoint can transfer in one service interval.  The xHCI
specification refers to this as the Maximum Endpoint Service Interval Time
Payload (Max ESIT Payload).  This is used by the hardware for bandwidth
management and scheduling of packets.

For SuperSpeed endpoints, the maximum is calculated by multiplying the max
packet size by the number of bursts and the number of opportunities to
transfer within a service interval (the Mult field of the SuperSpeed
Endpoint companion descriptor).  Devices advertise this in the
wBytesPerInterval field of their SuperSpeed Endpoint Companion Descriptor.

For high speed devices, this is taken by multiplying the max packet size by the
"number of additional transaction opportunities per microframe" (the high
bits of the wMaxPacketSize field in the endpoint descriptor).

For FS/LS devices, this is just the max packet size.

The other thing we must set in the endpoint context is the Average TRB
Length.  This is supposed to be the average of the total bytes in the
transfer descriptor (TD), divided by the number of transfer request blocks
(TRBs) it takes to describe the TD.  This gives the host controller an
indication of whether the driver will be enqueuing a scatter gather list
with many entries comprised of small buffers, or one contiguous buffer.

It also takes into account the number of extra TRBs you need for every TD.
This includes No-op TRBs and Link TRBs used to link ring segments
together.  Some drivers may choose to chain an Event Data TRB on the end
of every TD, thus increasing the average number of TRBs per TD.  The Linux
xHCI driver does not use Event Data TRBs.

In theory, if there was an API to allow drivers to state what their
bandwidth requirements are, we could set this field accurately.  For now,
we set it to the same number as the Max ESIT payload.

The Average TRB Length should also be set for bulk and control endpoints,
but I have no idea how to guess what it should be.

USB: xhci: properly set the "Mult" field of the endpoint context.

A SuperSpeed interrupt or isochronous endpoint can define the number of
"burst transactions" it can handle in a service interval.  This is
indicated by the "Mult" bits in the bmAttributes of the SuperSpeed
Endpoint Companion Descriptor.  For example, if it has a max packet size
of 1024, a max burst of 11, and a mult of 3, the host may send 33
1024-byte packets in one service interval.

We must tell the xHCI host controller the number of multiple service
opportunities (mults) the device can handle when the endpoint is
installed.  We do that by setting the Mult field of the Endpoint Context
before a configure endpoint command is sent down.  The Mult field is

usb: Fix tusb6010 for DMA API

Commit 18eabe2347ae7a11b3db768695913724166dfb0e introduced
DMA buffer ownership. Fix tusb6010 accordingly. To compile,
also dummy musb_platform_save and restore functions need to
be added.

Also change the order of musb_read_fifo() to happen after
dma_cache_maint to have the DMA operations completed before
moving the remaining unaligned bytes with PIO. The DMA
access and PIO touch different areas of the FIFO, so this
change only makes the code a bit easier to follow.

Tested on n810 and g_ether with variable size ping test.
The test seems to fail for some ping sizes, but that seems to
be a different problem.
