[parisc-linux] 2.4.20-pa27 64bits smp problem!

[Joel Soete]

Hi all,

Having the opportunity to test a N-class (classical), I build a sd with
debian unstable running a kernel 2.4.20-pa27 64bits up and would try now
to rebuild this same kernel with smp support (I am reach of 2cpu  :) ) but
compile failled with following message:

hppa64-linux-gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-pa27-64/include -Wall
-Wst
rict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame

make[1]: *** [first_rule] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.20-pa27-64/kernel'
make: *** [_dir_kernel] Error 2

at this 93th line I met:
rwlock_t tasklist_lock __cacheline_aligned = RW_LOCK_UNLOCKED

which is precompile as:
rwlock_t tasklist_lock __attribute__((__aligned__(64))) = (rwlock_t) { (spinlock_t)
{1}, 0 };

What's wrong?

I am using the last I know gcc-hppa64 3.2.3-0.1 (would I have to prefer
previous release?) .

Thanks in advance,
    Joel
