These particular files were just assuming that module.h was
somehow in the include paths. Give them the more minimalist
header file explicitly.

__kfree_rcu() in rcupdate.h bugs when parameter offset is not a constant
at compile time. Since we build the kgdb_test module with -O0 and it
includes this header file, we hit the bug. So drop the -O0 and mark the
one func we need for the test as noinline (so we can set a breakpoint on
it and have it be hit).

This patch removes all the module loader hook implementations in the
architecture specific code where the functionality is the same as that
now provided by the recently added default hooks.

The bug in the BF526 rom when doing a software reset exists only in older
silicon versions, so don't clear SWRST on newer parts.

Back in commit c03c2a8734, we fixed logic in the non-bf54x
GPIO resume code to set the data levels properly before the direction
to avoid spurious line glitches. But we missed the bf54x code paths.
So add the same fix there.

Re-architect how we save/restore the gpio/port logic that only pertains
to bf538/bf539 parts by pulling it out of the core code paths and pushing
it out to bf538-specific locations.

For now, this only supports gptimers. Support for dedicated PWM devices
as found on newer parts to come.

The alignment is normally handled by PERCPU(), but we need to do it
ourselves in the XIP build due to the custom layout.

Now that asm/gptimers.h has the hardware register struct layout, there's
no need to duplicate things locally.

Passing a non-simple expression in as the addr arg could incorrectly
apply the pointer cast resulting in misbehavior. Add proper paren.

The address limit is already set in flush_old_exec() so this

The documentation for the IMDMA channels appears to be incorrect.
These DMA blocks don't actually have PERIPHERAL_MAP MMRs for us
to access. Attempts to do so lead to system mmr hardware errors.

This moves the double fault data used at boot time into a single struct
which can then easily be addressed with indexed loads rather than having
to explicitly load multiple addresses.

The documentation is a little iffy as to whether these are actual MMRs,
but reading them on the hardware works, and the previous version of this
logic (the SDH) had PID[4567]. So add it for RSI too.

This code was mostly developed against a BF54x, so some BF537-specific
issues were missed.
The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse
of the EPPI block).
The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the
sim does not catch misreads here so that'll need to get fixed.
The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct
to figure that out rather than hardcoding it locally.

The Blackfin percpu input sections are outdated, so rather than update
them, drop them completely and use the new common define.

Anomaly 05000480 on BF537 rev 0.0, 0.1, 0.2:
Multiple Simultaneous Urgent DMA Requests May Cause DMA System Instability
Suggested Workaround:
Program the DMA Traffic Control Period to a non-zero value. This forces
the DMA block to group accesses together rather than allow arbitration for
each piece of data placed on the internal DMA bus.
