[IA64] move SAL_CACHE_FLUSH check later in boot
The check to see if the firmware drops interrupts during a SAL_CACHE_FLUSH is done to early in the boot. 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. Signed-off-by Troy Heber <troy.heber@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
