In arch/ppc/kernel/head.S the following code segment exists:

        mfmsr   r0
        ori     r0,r0,MSR_DR|MSR_IR
        mtspr   SRR1,r0
        lis     r0,start_here at h
        ori     r0,r0,start_here at l
        mtspr   SRR0,r0

However, when I do objdump on head.o this is what appears:

00000088 <turn_on_mmu>:
      88:       7c 00 00 a6     mfmsr   r0
      8c:       60 00 00 30     ori     r0,r0,48
      90:       7c 1b 03 a6     mtsrr1  r0
      94:       3c 00 00 00     lis     r0,0
      98:       60 00 00 00     nop
      9c:       7c 1a 03 a6     mtsrr0  r0
      a0:       4c 00 00 64     rfi

It appears that the code which loads the address of the label start_here
does not get assembled correctly. Is this observation correct?

I'm building for the est8260 target.
