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.
