Sam Ravnborg a00736e936 sparc: copy sparc64 specific files to asm-sparc 
Used the following script to copy the files:
cd include
set -e
SPARC64=`ls asm-sparc64`
for FILE in ${SPARC64}; do
	if [ -f asm-sparc/$FILE ]; then
		echo $FILE exist in asm-sparc
	else
		git mv asm-sparc64/$FILE asm-sparc/$FILE
		printf "#include <asm-sparc/$FILE>\n" > asm-sparc64/$FILE
		git add asm-sparc64/$FILE
	fi
done

* bits in the AFSR. Bits associated with disrupting traps must be cleared before
* interrupts are re-enabled to prevent multiple traps for the same error. I.e.
* PSTATE.IE and AFSR bits control delivery of disrupting traps.
*
* Since there is only one AFAR, when multiple events have been logged by the
* bits in the AFSR, at most one of these events will have its status captured
* in the AFAR. The highest priority of those event bits will get AFAR logging.
* The AFAR will be unlocked and available to capture the address of another event
* as soon as the one bit in AFSR that corresponds to the event logged in AFAR is
* cleared. For example, if AFSR.CE is detected, then AFSR.UE (which overwrites
* the AFAR), and AFSR.UE is cleared by not AFSR.CE, then the AFAR will be unlocked
* and ready for another event, even though AFSR.CE is still set. The same rules
* also apply to the M_SYNDROME and E_SYNDROME fields of the AFSR.
