Re: [PATCH] Use SLB size from the device tree

Michael Neuling writes:

Currently we hardwire the number of SLBs but the PAPR says we export an
ibm,slb-size property to specify the number of SLB entries.  This patch
uses this property instead of assuming 64 always.  If no property is
found, we assume 64 entries as before.

On 32-bit platforms (e.g. powermac) I get:

/home/paulus/kernel/powerpc/arch/powerpc/kernel/prom.c: In function 'check_cpu_slb_size':
