This ugly hack was long overdue to die.
It was a way to print out Sparc interrupts in a more freindly format,
since IRQ numbers were arbitrary opaque 32-bit integers which vectored
into PIL levels. These 32-bit integers were not necessarily in the
0-->NR_IRQS range, but the PILs they vectored to were.
The idea now is that we will increase NR_IRQS a little bit and use a
virtual<-->real IRQ number mapping scheme similar to PowerPC.
That makes this IRQ printing hack irrelevant, and furthermore only a
handful of drivers actually used __irq_itoa() making it even less
useful.

without CONFIG_PROC_FS).

SPARC DBRI driver
This patch contains the following fixes to the Alsa DBRI driver:
- Remove 2.6.13 build warning on the prom_getproperty() call.
- Rework command synchronization: send a sequence number with D_WAIT,
and check it in the completion interrupt.
Move synchronization delays from _cmdsend() to _cmdlock() allowing the
CPU to do other usefull things while the DBRI is processing the
commands.
- Fix first argument of printk() calls.
- Enable burst transfers for DBRI. Original 2.4 patch from Krzysztof
Helt
- Make dbri_debug module parameter writable from sysfs. Remove obsolete
write access to the /proc debug file.
- Replace udelay() with msleep_interruptible() where possible.
- Update documentation comments.
