parisc: Bump 64-bit IRQ stack size to 64 KB
[ Upstream commit 31680c1d1595a59e17c14ec036b192a95f8e5f4a ]
Bump 64-bit IRQ stack size to 64 KB.
I had a kernel IRQ stack overflow on the mx3210 debian buildd machine. This patch increases the
64-bit IRQ stack size to 64 KB. The 64-bit stack size needs to be larger than the 32-bit stack
size since registers are twice as big.
