The hwmod and PRCM data should be moved out either to DT data or
to drivers/.  Also, the current implementation trades off lines
of diff by dynamically rewriting static data at runtime, which is
a bad practice - it causes future maintenance headaches.
However, after speaking with my upstream, it sounds like it's
better to merge these patches in their current state, due to long
term considerations.

Basic test logs are here:

http://www.pwsan.com/omap/testlogs/am43xx_support_v3.13/20131015213706/

Due to the lack of an AM43xx board and any available public
documentation, it's impossible for me to review or test that
platform in any meaningful way.  But at least the tests above
verify that the patches don't affect existing platforms -
particularly AM33xx.

I've tested the serial, MMC, smsc911x, wl12xx, and off-idle support
with the pinctrl patches, so it probably works better than the
board-*.c files ever did. Also the board-omap3evm.c file is broken
for the DSS, and has been for a while. Patches are welcome to fix
it in this .dts file, let's just drop the board-*.c file for this.

Note that off-idle currently requires doing request_irq() on the
wake-up pin from pinctrl-single IRQ domain until we can handle
that in some Linux generic way.

Pull parisc fixes from Helge Deller:
 "This patchset includes a bugfix to prevent a kernel crash when memory
  in page zero is accessed by the kernel itself, e.g.  via
  probe_kernel_read().

  Furthermore we now export flush_cache_page() which is needed
  (indirectly) by the lustre filesystem.  The other patches remove
  unused functions and optimizes the page fault handler to only evaluate
  variables if needed, which again protects against possible kernel
  crashes"

parisc: optimize variable initialization in do_page_fault

The attached change defers the initialization of the variables tsk, mm
and flags until they are needed. As a result, the code won't crash if a
kernel probe is done with a corrupt context and the code will be better
optimized.

11 years agoparisc: fix interruption handler to respect pagefault_disable()
Helge Deller [Tue, 1 Oct 2013 19:54:46 +0000 (21:54 +0200)]
parisc: fix interruption handler to respect pagefault_disable()

Running an "echo t > /proc/sysrq-trigger" crashes the parisc kernel.  The
problem is, that in print_worker_info() we try to read the workqueue info via
the probe_kernel_read() functions which use pagefault_disable() to avoid
crashes like this:
    probe_kernel_read(&pwq, &worker->current_pwq, sizeof(pwq));
    probe_kernel_read(&wq, &pwq->wq, sizeof(wq));
    probe_kernel_read(name, wq->name, sizeof(name) - 1);

The problem here is, that the first probe_kernel_read(&pwq) might return zero
in pwq and as such the following probe_kernel_reads() try to access contents of
the page zero which is read protected and generate a kernel segfault.

With this patch we fix the interruption handler to call parisc_terminate()
directly only if pagefault_disable() was not called (in which case
preempt_count()==0).  Otherwise we hand over to the pagefault handler which
will try to look up the faulting address in the fixup tables.
