I applied all these to the ppc64 kernel (you missed ppc64 btw) and it dies.
Quite late in boot, during floppy_init->init_disk_stats->alloc_percpu.
I'm reduced to debugging with printk on ppc64. __alloc_percpu() calls
new_block(), loops around and then dies in here:
#define D() printk("at %s:%d\n", __FILE__, __LINE__)
D();
/* Transfer extra to previous block. */
if (b->size[i-1] < 0)
b->size[i-1] -= extra;
else
b->size[i-1] += extra;
b->size[i] -= extra;
ptr += extra;
D();
Not sure what happened - no oops, no xmon, no sysrq, no nuthin. It even
manages to lock up minicom on the other end of the cable. Impressed.
