SAL_CACHE_FLUSH expects to be able to make PAL calls in virtual mode, on some cell based machines a fault occurs causing a MCA. This patch moves the check after mmu_context_init so the TLB and VHPT are properly setup.

Usually, the cache check and bus check target identifiers have the same address. On Montecito the cache check and bus check target identifiers can be different if a corrected error (ie SBE or unconsumed poison data) was encountered and then an uncorrected error (ie DBE) was consumed. In that case, the cache check target identifier is the physical address of the DBE (that caused the MCA to surface) while the bus check target identifier is the physical address of the SBE. This patch correctly finds the target identifier that triggered the MCA. If there are multiple valid cache target identifiers in the same error record then use the one with the lowest cache level.
