Paul Mackerras dfbe0d3b6b [POWERPC] Fix boot failure on POWER6 ... Commit 473980a993 added a call to clear the SLB shadow buffer before registering it. Unfortunately this means that we clear out the entries that slb_initialize has previously set in there. On POWER6, the hypervisor uses the SLB shadow buffer when doing partition switches, and that means that after the next partition switch, each non-boot CPU has no SLB entries to map the kernel text and data, which causes it to crash. This fixes it by reverting most of 473980a9 and instead clearing the 3rd entry explicitly in slb_initialize. This fixes the problem that 473980a9 was trying to solve, but without breaking POWER6.
