This enables support for hardware-assisted userspace hardirq
|
||
|
|
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.
|
||
|
|
|

|
|
If in doubt, say N.
