David Gibson 533f08172e [PATCH] ppc64: dynamically allocate segment tables ... PPC64 machines before Power4 need a segment table page allocated for each CPU. Currently these are allocated statically in a big array in head.S for all CPUs. The segment tables need to be in the first segment (so do_stab_bolted doesn't take a recursive fault on the stab itself), but other than that there are no constraints which require the stabs for the secondary CPUs to be statically allocated. This patch allocates segment tables dynamically during boot, using lmb_alloc() to ensure they are within the first 256M segment. This reduces the kernel image size by 192k... Tested on RS64 iSeries, POWER3 pSeries, and POWER5.
