drivers/platform/x86/dell-smo8800.c is touched due to the following obscenity: drivers/platform/x86/dell-smo8800.c -> linux/interrupt.h -> linux/hardirq.h -> asm/hardirq.h -> linux/irq.h -> asm/hw_irq.h -> asm/sections.h -> asm/uaccess.h is the only chain of includes pulling asm/uaccess.h there.

* The exception table consists of triples of addresses relative to the
|
|
* exception table entry itself. The first address is of an instruction
|
|
* that is allowed to fault, the second is the target at which the program
|
|
* should continue. The third is a handler function to deal with the fault
|
|
* caused by the instruction in the first field.
|
|
*
|
|
* All the routines below use bits of fixup code that are out of line
|
|
* with the main instruction path. This means when everything is well,
|
|
* we don't even have to jump over them. Further, they do not intrude
|
|
* on our cache or tlb entries.
