The macb driver expects clocks with the names "pclk" and "hclk". We
currently provide "macb_clk" but to fit in line with other
architectures (namely AVR32), provide "pclk" and a fake "hclk".

Receiver-side copying of packets is based on this implementation, it gives
better performance and better CPU accounting. It totally supports three types:
full-page, sub-page and transitive grants.
However this patch does not cover sub-page and transitive grants, it mainly
focus on Full-page part and implements grant table V2 interfaces corresponding
to what already exists in grant table V1, such as: grant table V2
initialization, mapping, releasing and exported interfaces.
Each guest can only supports one type of grant table type, every entry in grant
table should be the same version. It is necessary to set V1 or V2 version before
initializing the grant table.
Grant table exported interfaces of V2 are same with those of V1, Xen is
responsible to judge what grant table version guests are using in every grant
operation.
V2 fulfills the same role of V1, and it is totally backwards compitable with V1.
If dom0 support grant table V2, the guests runing on it can run with either V1
or V2.

This patch introduces new structures of grant table V2, grant table V2 is an
extension from V1. Grant table is shared between guest and Xen, and Xen is
responsible to do corresponding work for grant operations, such as: figure
out guest's grant table version, perform different actions based on
different grant table version, etc. Although full-page structure of V2
is different from V1, it play the same role as V1.

in Configuration Register 3. The other ones will generate an abort
when trying to signal the end of the transaction so they are useless
in non-secure mode.

The Kconfig options for the PL310 errata workarounds do not use a

This patch tidies up the options by ensuring that the bool descriptions
are prefixed with "PL310 errata:" and the config options are prefixed
with PL310_ERRATA_, making it much clearer in menuconfig as to what the
workarounds are for.

This patch implements a workaround for PL310 erratum 769419. On
revisions of the PL310 prior to r3p2, the Store Buffer does not
automatically drain. This can cause normal, non-cacheable writes to be
retained when the memory system is idle, leading to suboptimal I/O
performance for drivers using coherent DMA.
This patch adds an optional wmb() call to the cpu_idle loop. On systems
with an outer cache, this causes an explicit flush of the store buffer.

The poodle restart handler was added in 74617fb6b8 (3593/1: Add reboot
and shutdown handlers for Zaurus handhelds), and at that time it was
necessary to deal with the RCSR register. This commit also forced all
restarts to use the 'hard' restart method.
In dc38e2ad53 (pxa: Fix RCSR handling), the RCSR handling was removed,
leaving just the forcing to use a 'hard' restart. As hard restarts are
the default (in the absense of a reboot= command line argument), this
seems pointless. In any case, Richard Purdie says:

We only need to set the system up for a soft-restart if we're going to
be doing a soft-restart. Provide a new function (soft_restart()) which
does the setup and final call for this, and make platforms use it.
Eliminate the call to setup_restart() from the default handler.
This means that platforms arch_reset() function is no longer called with
the page tables prepared for a soft-restart, and caches will still be
enabled.

Prevent tracing of preempt_disable() in get_cpu_var() in
kvm_clock_read(). When CONFIG_DEBUG_PREEMPT is enabled,
preempt_disable/enable() are traced and this causes the function_graph
tracer to go into an infinite recursion. By open coding the
preempt_disable() around the get_cpu_var(), we can use the notrace
version which prevents preempt_disable/enable() from being traced and
prevents the recursion.
