      powerpc/pseries: Disable VPNH feature · 36e8695c
      Benjamin Herrenschmidt 提交于
      This feature triggers nasty races in the scheduler between the
      rebuilding of the topology and the load balancing code, causing
      the machine to hang.
      
      Disable it for now until the races are fixed.

      powerpc/iseries: Fix early init access to lppaca · f2f6dad6
      Benjamin Herrenschmidt 提交于
      The combination of commit
      
      8154c5d2 and
      93c22703
      
      Broke boot on iSeries.
      
      The problem is that iSeries very early boot code, which generates
      the device-tree and runs before our normal early initializations
      does need access the lppaca's very early, before the PACA array is
      initialized, and in fact even before the boot PACA has been
      initialized (it contains all 0's at this stage).
      
      However, the first patch above makes that code use the new
      llpaca_of(cpu) accessor, which itself is changed by the second patch to
      use the PACA array.
      
      We fix that by reverting iSeries to directly dereferencing the array. In
      addition, we fix all iterators in the iSeries code to always skip CPU
      whose number is above 63 which is the maximum size of that array and
      the maximum number of supported CPUs on these machines.
      
      Additionally, we make sure the boot_paca is properly initialized
      in our early startup code.
