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 Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

26 * 1) As the result of an instruction fetch, will generate instruction_access_error
27 * 2) As the result of a load etc. will generate data_access_error.
28 * 3) As the result of store merge completion, writeback, or copyout will
29 * generate a disrupting ECC_error trap.
30 * 4) As the result of such errors on instruction vector fetch can generate any
31 * of the 3 trap types.
