Untested, but this should fix up the bulk of the totally mechanical
issues, and should make the actual detail fixing easier.

Add the necessary call to register_isa_ports() so that glibc knows

Patch from David Brownell
ARM genirq cleanups/updates:
- Start switching platforms to newer APIs
* use "irq_chip" name, not "irqchip"
* providing irq_chip.name
- Show irq_chip.name in /proc/interrupts, like on x86.
This update a bit more than half of the ARM code. The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).

The irgflags consolidation did conflict with the ARM to generic IRQ
conversion and was not applied for ARM. Fix it up.

Both Integrator and Versatile were using set_irq_handler() and
enable_irq(), and working around the initialisation of the
chained interrupt, instead of the more correct
set_irq_chained_handler() function. Fix Integrator and
Versatile to use the right function, and remove these work-arounds.

The amba-pl010 hardware does not provide RTS and DTR control lines; it
is expected that these will be implemented using GPIO. Allow platforms
to supply a function to implement manipulation of modem control lines.

A change to the SMP initialisation caused the following oops:
CPU1: Booted secondary processor
CPU1: D VIPT write-back cache
CPU1: I cache: 32768 bytes, associativity 4, 32 byte lines, 256 sets
CPU1: D cache: 32768 bytes, associativity 4, 32 byte lines, 256 sets
<7>Calibrating delay loop... 83.14 BogoMIPS (lpj=415744)
<1>Unable to handle kernel NULL pointer dereference at virtual address 0000001c
...
PC is at enqueue_task+0x1c/0x64
LR is at activate_task+0xcc/0xe4
SMP initialisation now requires cpu_possible_map to be initialised in
setup_arch(). Move this from smp_prepare_cpus() to smp_init_cpus()
and call it from our setup_arch() if CONFIG_SMP is enabled.

This patch moves the rtc_interrupt() prototype to rtc.h and removes the
prototypes from C files.

Manual #include fixups for clashes - there may be some unnecessary
|
|
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.
In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.

This is part of Thomas Gleixner's generic IRQ patch, which converts
ARM to use the generic IRQ subsystem. Here, we wrap calls to
desc->handler() in an inline function, desc_handle_irq(). This
reduces the size of Thomas' patch since the changes become more
localised.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
