[PATCH] Alpha: Remove redundant local asm header redirections

[PATCH] Alpha: Remove redundant local asm header redirections

[Maciej W. Rozycki]

Remove a number of asm headers locally redirected to the respective 
generic or generated versions.

For asm-offsets.h all that is needed is a Kbuild entry for the generic 
version, and for div64.h, irq_regs.h and kdebug.h nothing is needed as 
in their absence they will be redirected automatically according to 
include/asm-generic/Kbuild.

Hi,

 Noticed while fiddling with Kbuild for PARPORT_PC.  Please apply.

 BTW, has anybody heard from Richard Henderson lately?  His twiddle.net 
domain no longer resolves, and it was like this with the previous ping 
already.

Maybe Andrew Morton could pick the fix up if the original maintainer is currently
not responding?

Sorry for the delay. I'll apply this. I just haven't had much time for
alphas lately.

Maybe now's a good time to remind you that I'm still waiting on you to
upstream the m41t80/SWARM/i2c/smbus patches? It's been more than 11
years now, so it seems long enough for a ping :)

 No worries, and thanks for chiming in.  I plan to get one of my Alphas 
set up and wired in my remote lab later this year, so I hope to get a bit 
more active with the port.  At least I've got a reasonably recent build of 
the toolchain:

$ alpha-linux-gnu-gcc --version
alpha-linux-gnu-gcc (GCC) 12.0.1 20220129 (experimental)
[...]

 Umm, right, I came across them recently!  I'll see what I can do, however 
I don't have my SWARM in my remote lab, so I can only verify things when 
I'm next to it (which has been occasional only since the start of the 
bloody pandemic).  As I recall there was an issue with the incompatibility 
of the SMBUS protocol subset implemented by the SOC and the RTC causing a 
race.  I've had more stuff outstanding, such as PHY IRQ support for the 
Ethernet interfaces.

 And I yet have to see why my compiler miscompiled one endianness of CFE 
too (and find a way to publish my CFE fixes)!

Thanks for the patch! This was included in my pull request today and
is now upstream in Linus' tree.

 Great, thanks!  And BTW my Alpha has been relocated and was scheduled for 
wiring back in Jan, but events beyond my control have prevented this from 
happening.  I have it planned late Mar now, so fingers crossed I'll be 
able to do some more soon.
