Custom kernel for DS5000 does no longer compile

[Erik Bertelsen]

My DS5000 can no longer compile its custom-configured kernel, but gives:

compile SOCKDEV/dec_3min.o
../../../../arch/pmax/pmax/dec_3min.c: In function 'dec_3min_tc_init':
../../../../arch/pmax/pmax/dec_3min.c:506: error:
'mips3_cp0_count_read' undeclared (first use in this function)
../../../../arch/pmax/pmax/dec_3min.c:506: error: (Each undeclared
identifier is reported only once
../../../../arch/pmax/pmax/dec_3min.c:506: error: for each function it
appears in.)


The kernel configuration file contains options MIPS1 and DEC_3MIN but
not MIPS3. By looking around in the code, I discovered that by adding
MIPS32 explicitly to the kernel configuration file, the resulting
kernel builds and boots.

I tried this because mips/locore.h declares mips3_cp0_count_read if
any of MIPS3, MIPS4, MIPS32, or MIPS64 is defined.

But by looking at the kernel configuration files coming with NetBSD I
really just consider this a kludge and not a solution. I'm not even
sure whether mips3_cp0_count_read should be declared or the call to it
should be skipped for my machine.

For reference my previous kernel was compiled on Dec 2nd last year (4.99.38).

Such mips3 stuff (for DS5000/150) should be wrapped
with #if defined(MIPS3)?

I can confirm that my kernel builds and runs with the patch above -- thank you
