Ben-san,
It should have been set in setup_64.c, in setup_paca() (which is
called
twice) in that statement:
local_paca = paca[cpu];
As local_paca is defined as being a variable held in register r13.
Maybe
something bad's happening with the compiler ?
Can you check early_setup
Also, you may want to try adding --ffixed-r13 to the CFLAGS in the
makefile and let us know if it makes a difference... r13 is marked
reserved by the ABI but segher seems to imply that gcc may decide to
ues
it anyway (ouch !)
That's what I thought for a second, but I misread the GCC
initializing SLB

This is a workaround NOT to insert EA=0 entry at initializing SLB.
Without this patch, you can see /sbin/init hanging at a machine
which has less or equal than 256MB memory.
Can you elaborate? I don't understand why /sbin/init will hang
