The DVB framework will try to power-down an adapter that no-one is using
any more, but this assumes that the adapter is still connected to the

There were a several problems in this function:
1) Potential integer overflow in the comparison:
if (fio.write_len + fio.read_len > 1028) {
2) If the user gave bogus values for write_len and read_len then
returning -EINVAL is more appropriate than returning -ENOMEM.
3) wbuf was set to the address of an array and could never be NULL
so I removed the pointless NULL check.
4) The call to vfree(wbuf) was improper. That array is part of a
larger struct and isn't allocated by itself.
5) flashio() can't actually fail, but we may as well add error
handling in case this changes later.
6) In the default case where an ioctl is not implemented then
returning -ENOTTY is more appropriate than returning -EFAULT.

This patch implements an i2c_gate_ctrl op for the cxd2820r. Thanks to Robert
Schlabbach for identifying the register address and field to set.
The old i2c intercept code that prefixed messages with a passthrough byte has
been removed and the PCTV nanoStick T2 290e entry in em28xx-dvb has been
updated appropriately.
Tested for DVB-T2 use; I would appreciate it if somebody with DVB-C capabilities
could test it as well - from inspection I cannot see any problems.
This is patch v2. It fixes some schoolboy style errors and removes superfluous
i2c entries in cxd2820r.h.

Tuners in general convert a high frequency carrier into an Intermediate
Frequency (IF).
Digital tuners like tda18271, xc3028, etc. generally allow changing the IF
frequency, although they generally have recommented settings for the IF.
Analog tuners, have a fixed IF frequency, that depends on the physical
characteristics of some analog components.
For digital tuners, it makes sense to have ways to configure IF,
via the tuner's configuration structure, like what's done inside the
tda18271-fe maps.
The demods need to know what IF is used by the tuner, as it will need
to convert internally from IF into baseband. Currently, the bridge driver
needs to fill a per-demod configuration struct for it, or pass it via
a dvb_attach parameter.
The tda18271 datasheet recommends to use different IF's for different
delivery system types and for different bandwidths.
The DRX-K demod also needs to know the IF frequency in order to work,
just like all other demods. However, as it accepts different delivery
systems (DVB-C and DVB-T), the IF may change if the standard and/or
bandwidth is changed.
So, the usual procedure of passing it via a config struct doesn't work.
One might try to code it as two separate IF frequencies, or even as a
table in function of the delivery system and the bandwidth, but this
will be messy.
So, it is better and simpler to just add a new callback for it and
require the tuners that can be used with MFE frontends like drx-k
to implement a new callback to return the used IF.

The one in-tree videobuf2-dma-sg driver (mmp-camera) has no need for a
kernel-space mapping of the buffers; one suspects that most other drivers
would not either. The videobuf2-dma-sg module does the right thing if
buf->vaddr == NULL - it maps the buffer on demand if somebody needs it. So
let's not map the buffer at allocation time; that will save a little CPU
time and a lot of address space in the vmalloc range.

We have hit a couple of customer bugs where they would like to
use those parameters to run an UP kernel - but both of those
options turn of important sources of interrupt information so
we end up not being able to boot. The correct way is to
pass in 'dom0_max_vcpus=1' on the Xen hypervisor line and
the kernel will patch itself to be a UP kernel.

If vmalloc page_fault happens inside of interrupt handler with interrupts
disabled then on exit path from exception handler when there is no pending
interrupts, the following code (arch/x86/xen/xen-asm_32.S:112):
cmpw $0x0001, XEN_vcpu_info_pending(%eax)
sete XEN_vcpu_info_mask(%eax)
will enable interrupts even if they has been previously disabled according to

testb $X86_EFLAGS_IF>>8, 8+1+ESP_OFFSET(%esp)

but not clearing it if there isn't any pending events.
