commit b132ac51d7a50c37683be56c96ff64f8c887930f upstream.
Move sequence of masking and unmasking global interrupts from buttress interrupt handler to generic one that handles both VPUIP and BTRS interrupts. Unmasking global interrupts will re-trigger MSI for any pending interrupts.
Lack of this sequence will cause the driver to miss any VPUIP interrupt that comes after reading VPU_37XX_HOST_SS_ICB_STATUS_0 and before clearing all active interrupt sources.
