Currently the kernel is ambigously treating GPIOs and interrupts
from a GPIO controller: GPIOs and interrupts are treated as
orthogonal. This unfortunately makes it unclear how to actually
retrieve and request a GPIO line or interrupt from a GPIO

The functionality of rbtree_ctx->cached_rbnode is broken. Remove it to

rbnode register ranges can overlap, which is not a problem as long as

This is incidentally yet another example of "PV/weird platform violence", since

The current kpropes insn caches allocate memory areas for insn slots with
module_alloc(). The assumption is that the kernel image and module area
are both within the same +/- 2GB memory area.

The two insn caches (insn, and optinsn) each have an own mutex and
alloc/free functions (get_[opt]insn_slot() / free_[opt]insn_slot()).
Since I need yet another insn cache which satifies dma allocations,
unify and simplify the current implementation:
- Move the per insn cache mutex into struct kp
With the general-instruction extension facility (z10) a couple of
instructions with a pc-relative long displacement were introduced.
The kprobes support for these instructions however was never implemented.
In result, if anybody ever put a probe on any of these instructions the
result would have b

Hi Doug,
Do you have any update for this series?
Please let me know.

Dan Carpenter's automatic Smatch checker found an anomaly in the ux500
MUSB driver, whereby board data was checked before use in all but one
occasion. It is believed that it needs to be checked every time.

In case of big endian CPU we have to convert either all fields in the structure
or leave this job to ACPICA. The second choice seems the best.
So, let's remove the ugly conversion that is not fully comprehensive anyway.

ACPI DMA provides managed function to register the slave DMA controller in the
internal container. This patch anounces that function in the corresponding

Pin control utility functions provides the function for creating
map lists.
In place of implementing APIs locally in Tegra pin control driver
for creating map lists, use the utility functions. This reduces
the code size and avoid duplication.

Add support to pass the config type like GROUP or PIN when using
the utils or generic pin configuration APIs. This will make the
APIs more generic.
Added additional inline APIs such that it can be use directly as
callback for the pinctrl_ops.

We are using the same trick in previous patch.
Introduce a "bool is_phys" to acpi_initrd_override(). When it
is true, convert all golbal variables va to pa, so that we can
access them on 32bit before paging is enabled.
NOTE: Do not call printk() on 32bit before paging is enabled
because it
