  "message": "[POWERPC] Fix boot failure on POWER6\n\nCommit 473980a99316c0e788bca50996375a2815124ce1 added a call to clear\nthe SLB shadow buffer before registering it.  Unfortunately this means\nthat we clear out the entries that slb_initialize has previously set in\nthere.  On POWER6, the hypervisor uses the SLB shadow buffer when doing\npartition switches, and that means that after the next partition switch,\neach non-boot CPU has no SLB entries to map the kernel text and data,\nwhich causes it to crash.\n\nThis fixes it by reverting most of 473980a9 and instead clearing the\n3rd entry explicitly in slb_initialize.  This fixes the problem that\n473980a9 was trying to solve, but without breaking POWER6.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n",
