This replaces drm_mtrr_{add,del} with drm_mtrr_{add,del}_wc. The
interface is simplified (because the base and size parameters to
drm_mtrr_del never did anything) and it uses
mtrr_{add,del}_wc_if_needed to avoid allocating MTRRs on systems
that don't need them.

The old code allowed very strange memory types. Now it works like
all the other video drivers: ioremap_wc is used unconditionally,
and MTRRs are set if PAT is unavailable (unless MTRR is disabled
by a module parameter).
UC, WB, and WT support is gone. If there are MTRR conflicts that prevent
add
i915 open-coded logic that was essentially equivalent to the new

A fair number of drivers (mostly graphics) add write-combining MTRRs.
Most ignore errors and most add the MTRR even on PAT systems which don't
need to use MTRRs.
This series adds new functions mtrr_{add,del}_wc_if_needed and
drm_mtrr_{add,del}_wc that report errors and do nothing if PAT is
enabled
These MTRR helpers add a WC MTRR if PAT is disabled. Modern drivers should
be using ioremap_wc, etc. to get WC memory; the MTRR is just a fallback
if the system doesn't have PAT. So, rather than allocating an unnecessary
MTRR even on PAT systems and having error handling spread out and handled

The routine disable_nonboot_cpus() shuts down cpus sequentially
using for_each_online_cpu(cpu) to call cpu_down() one cpu at
a time. cpu_down() calls __stop_machine() which stops all

cpus, only to do it all over again for the next c

I suspect the above changes are all a result of a search-and-replace

There are cases where all irq_chip_type instances have separate mask
registers, making a shared mask register cache unsuitable for the
purpose.
Introduce a new flag IRQ_GC_MASK_CACHE_PER_TYPE. If set, point the per

Since we already have an irq_data_get_chip_type() function which returns
a pointer to irq_chip_type, use that instead of cur_regs().

The ongoing device tree support for ARM is creating new irq chip
drivers in drivers/irqchip/ in a frenzy. Quite some of them are
ripping out the generic irq chip implementation from arch/arm/* and
just creating the same mess of duplicated code again, which was
cleaned up with the generic irq chip i
Some chips have weird bit mask access patterns instead of the linear
you expect. Allow them to calculate the cached mask themself.

Provide infrastructure for irq chip implementations which work on
linear irq domains.

the irq domain.
- Interface to get the generic chip pointer for a particular hardware
interrupt in the domain.

In ret_from_except_lite() with CONFIG_PREEMPT enabled,
add the missing check to compare value of preempt_count
with zero before continuing with preemption process of
the current task.
If preempt_count is non-zero, restore reg and return,
else continue the preemption process.

Make the "buf" input param of iscsit_do_crypto_hash_buf() "const void *".
This allows to remove lots of casts in its callers.
