The generic version uses a variable length of u32 registers instead of u32/u64.
This allows easier support for "wider" registers without having to rewrite
everything.
This "generic" version is as fast as the old version in the best case
(i == next set bit), and twice as fast in the worst case in 64 bits.
Using a macro was chosen over a (forced) inline version because gcc generated
more compact code with the macro.
The change from (signed) int to unsigned int for i and to_call was intentional
as the value can be only between 0 and (width - 1) anyway, and allowed gcc to
optimise the code a bit further.

This patch introduces common clock framework integration for all
configurable on-chip clocks on Alchemy chips:
- 2 or 3 PLLs which generate integer multiples of the root rate 12MHz,
- 6 dividers which take one of the 3 PLLs as input and divide their
rate by either multiples of 2 or 1 (Au1300).
- another bank of up to 6 muxes which take either one of the 6
above dividers or one of the PLLs directly and divide their rate
further by 1, 2, 3 or 4.
- a few other sources which are used by onchip peripherals and are
informational.
This implementation will take the clock tree as it was set up
by boot firmware: all in-kernel boards should continue to work
without having to set up the clock tree in board code.
CLK_IGNORE_DISABLED will be removed once all drivers have been
converted.

This patch changes the static memory controller registers to offsets
from base, prefixes them with AU1000_ to avoid silent failures due to
changed addresses and introduces helpers to access them.
No functional changes, comparing assembly of a few select functions shows
no differences.

This is required so that we give up the last reference to the device.
Also, create a gio_bus_release() that calls kfree on the device argument to
properly kfree() the memory allocated for the device.

In preparation to make the check_extension function available to VM scope
we add a struct kvm * argument to the function header and rename the function
accordingly. It will still be called from the /dev/kvm fd, but with a NULL
argument for struct kvm *.

The driver hasn't been cleaned up and it doesn't look like anyone is
working on it anymore (including the original author). So remove it.
If someone wants to work on cleaning the driver up and moving it out of
staging, this commit can be reverted.
In addition, since this removes the CONFIG_NET_VENDOR_SILICOM config
symbol, remove the symbol from all defconfig files that reference it.

ftrace_stop() is going away as it disables parts of function tracing
that affects users that should not be affected. But ftrace_graph_stop()
is built on ftrace_stop(). Here's another example of killing all of
function tracing because something went wrong with function graph
tracing.
Instead of disabling all users of function tracing on function graph
error, disable only function graph tracing. To do this, the arch code
must call ftrace_graph_is_dead() before it implements function graph.

Because of the removal of the scsi_tgt kernel module, the kbuild variables
CONFIG_SCSI_TGT, CONFIG_SCSI_SRP_TGT_ATTRS and CONFIG_SCSI_FC_TGT_ATTRS
are obsolete. This patch removes these variables. This patch is the result
of the following command:
find -name '*defconfig' | while read f; do grep -vwE 'CONFIG_SCSI_TGT|CONFIG_SCSI_SRP_TGT_ATTRS|CONFIG_SCSI_FC_TGT_ATTRS|CONFIG_SRP' $f >/tmp/t && mv /tmp/t $f; done
