[PATCH] irq: make SPARSE_IRQ an optionally hidden option

From: Rob Herring On ARM, we don't want SPARSE_IRQ to be a user visible option. Make SPARSE_IRQ visible based on MAY_HAVE_SPARSE_IRQ instead of depending on HAVE_SPARSE_IRQ. With this, SPARSE_IRQ is not visible on C6X and ARM. Signed-off-by: Rob Herring Cc: Russell King Cc: Mark Salter Cc: A

I have dumped TLB entries while mapping shared memory. On both cores M-Bit (MAS2[61]) is set in TLB0 entries. On both cores M-Bit is set for all valid TLB1 entries. TLB1 does contains some invalid entries which has M-Bit cleared. So I believe at this time the coherency is not the issue. Any furt
