genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

m68k/amiga,atari: Fix specifying multiple debug= parameters

2013-12-08T10:03:21+00:00

Since commit d6713b4091a99fa2af2fabdcd2f3fb97f32ecf2e ("m68k: early
parameter support"), the user can specify multiple debug consoles using the
"debug=" kernel command line parameter.
However, as there's only a single struct console object, which is reused,
it would actually register the same console object multiple times, causing
the following warning:

WARNING: CPU: 0 PID: 0 at kernel/printk/printk.c:2233 register_console+0x36/
console 'debug0' already registered

Make sure to register the console object only once, to avoid the warning.

Note that still only one console (the one corresponding to the last
"debug=" parameter) will be active at the same time, as the .write() method
of the already registered console object is overwritten by a subsequent
"debug=" parameter.

Use the beam position registers, which provide at least 17 bits of data
changing at 1.79 MHz.

zorro/UAPI: Use proper types (endianness/size) in

2013-11-26T10:09:09+00:00

Fix member definitions for non-native userspace handling:
  - All multi-byte values are big-endian, hence use __be*,
  - All pointers are 32-bit pointers under AmigaOS, but unused (except for
    cd_BoardAddr) under Linux, hence use __be32.

zorro: ZTWO_VADDR() should return "void __iomem *"

2013-11-26T10:09:07+00:00

ZTWO_VADDR() converts from physical to virtual I/O addresses, so it should
return "void __iomem *" instead of "unsigned long".

This allows to drop several casts, but requires adding a few casts to
accomodate legacy driver frameworks that store "unsigned long" I/O
addresses.

zorro: Do not allocate zorro_autocon[] statically

2013-11-26T10:09:03+00:00

Currently the array of Zorro devices is allocated statically, wasting
up to 4.5 KiB when running an Amiga or multi-platform kernel on a machine
with no or a handful of Zorro expansion cards. Convert it to conditional
dynamic memory allocation to fix this.

amiga_parse_bootinfo() still needs to store some information about the
detected Zorro devices, at a time even the bootmem allocator is not yet
available.  This is now handled using a much smaller array (typically less
than 0.5 KiB), which is __initdata and thus freed later.
