Christophe Leroy 1a736d98c8 Revert "powerpc/8xx: Always pin kernel text TLB" ... This reverts commit bccc58986a. When STRICT_KERNEL_RWX is selected, EXEC memory must stop where RW memory start. When pinning iTLBs it means an 8M alignment for RW data start. That may be acceptable on boards with a lot of memory but one of my supported boards only has 32 Mbytes and this forced alignment leads to a waste of almost 4 Mbytes with is more than 10% of the total memory. So revert commit bccc58986a ("powerpc/8xx: Always pin kernel text TLB") but don't restore previous behaviour in ITLB miss handler as now kernel PGD entries are copied into each process PGDIR.
