Currently the sh-intc driver is compiled on all SuperH and non-multiplatform SH-Mobile platforms, while it's only used on a limited number of platforms: - SuperH: SH2(A), SH3(A), SH4(A)(L) (all but SH5) - ARM: sh7372, sh73a0 Drop the "default y" on SH_INTC, make all CPU platforms that use it select it, and protect all sub-options by "if SH_INTC" to fix this.

masking.

SH-4A and newer interrupt blocks all support a special shadowed
|

page with all non-masking registers obscured when mapped in to
|
|
userspace. This is primarily for use by userspace device

drivers that are using special priority levels.
