>Description:
	The kcopy() function in sys/arch/arm32/arm32/bcopyinout.S does
	not work with the DIAGNOSTIC option.  The reason is that the
	common part of the copyinout routines check that curpcb is
	non-zero, but this is not necessary for kcopy().
>How-To-Repeat:
	Try to do an uiomove() in kernel space in an interrupt context.
>Fix:
	Move the test.
