I know I can fix the smp_num_cpus thing, but the prepare_arch_switch()
etc. things are another matter. Every now and again I see a post to lkml
for the Alpha, which suggest some people succeed in compiling it. Any
hints?

Thanks,

OK. Found it... Here...
    467 /*
    468  * fls: find last bit set.
    469  */
    470
    471 #define fls(x) generic_fls(x)

I took it out. I guess it's not needed anymore because of this:

    318 /*
    319  * fls: find last bit set.
    320  */
    321 #if defined(__alpha_cix__) && defined(__alpha_fix__)
    322 static inline int fls(int word)
    323 {
    324         long result;
    325         __asm__("ctlz %1,%0" : "=r"(result) : "r"(word &
0xffffffff));
    326         return 64 - result;
    327 }
    328 #else
    329 #define fls     generic_fls
    330 #endif

Right? :o)

I tried #define smp_num_cpus 1 in include/asm-alpha/smp.h (the non-smp
section) but the same line in include/asm/mmu_context.h works - for a
while.

I think this "bug" appears with some binutils some weeks/months old. Try
to upgrade them.

I'm not hitting this bug, but for me, ./arch/alpha/kernel/head.o isn't
build (actually, there aren't any .o files in that directory), even if
I try to explicitely compile head.o by 'make arch/alpha/kernel/head.o'.
Any hints there?

MfG, JBG

Hmm, I had an up-to-date debian testing system.
So I upgraded to the latest binutils from unstable, that didn't work.
Then I downloaded binutils-2.12.1 from source and installed that - still
doesn't work.
The latest from unstable was 2.12.90.0.9.

None, but could you please tell me what version of binutils you're
using?

I'm working with binutils-2.12.90.0.7-3 from Rawhide, because
my base-system is RedHat. And this version worked well.
I'm also using gcc-3.1-6 and glibc-2.2.4-24.

I hope this helps...

The patch worked well and did what my patch did not yet. :o)
I compiles without problems. I'll try to boot the machine
tommorow (at work).

I'll send you the results. :o)

I cannot boot the kernel... Here's the problem... But what does this
mean? "swapper"? Has this something to do with swap?
