However, look at this bug:
It's outside my knowledge to be able to fix for various reasons:
1. I don't know _anything_ about IXP4xx hardware, so I'm not the right
person to own this bug.
2. I've no idea who's looking after IXP4xx stuff now. (When it was
posted to the ARM kernel list by Rob, it was ignored so I guess the
IXP4xx maintainer isn't watching for bugs, if such a person even
3. I've little idea about why the MM page allocation is failing early.
4. The ARM DMA bounce code is a hack, and I'm pretty sure that this
failure is a result of trying to use this contorted code instead
of the relevant subsystems having a correct DMA mask.
Can you make any suggestion what should be done about this bug?
I'm personally very tempted to close it as "won't fix" (I wish there was
a "can't fix" category.)
As for my other bugs:
Again, EP93xx is not my thing, but I've recently merged a patch to allow
AMBA PL010 uarts (which are present on this platform) to use the clock
The EP93xx people (provided they're willing) now need to do whatever's
required to resolve that bug. (Hopefully they've taken ownership of
that bug now.)
I'm no longer serial maintainer. Bug IDs after about 7000 reflect bugs
submitted since I've resigned my serial maintainership, and therefore
I've ignored them. It's far easier to ignore bug reports in bugzilla
than it is to get categories reassigned (to whom? - dunno) or even
deleted (if no one steps up presumably that's what needs to happen?)
This one isn't a regression, or even a bug IMHO, but could be viewed as
undesirable behaviour. Fixing it is utterly non-trivial though.
A serial port which happens to have an IrDA device on it is still a serial
port at the end of the day, and as long as we have legacy probing, a serial
port at a standard COM port address will be detected as such. There's
never been any facility in the kernel to get around serial ports being
at standard COM port addresses.
Moreover, there's a whole class of applications which want IrDA devices
to be presented to userspace as a serial port rather than a special
network device, so unilaterally ignoring IrDA devices which look like
serial is not really an option.
Basically, IrDA and serial need to develop a way to work in harmony
with each other. That's a long-term thing though.
