Are ALCOR and XLT kernels interchangeable? And is XLT or Alcor the
right one for XL300? I have found only one difference in the kernel
source between the two: the initialisation of of the
./arch/alpha/kernel/irq.c
the init of GRU_INT_REQ_BITS
from the definitions os asm-alpha/cia.h:
#define ALCOR_GRU_INT_REQ_BITS          0x800fffffUL
#define XLT_GRU_INT_REQ_BITS            0x80003fffUL
