RH-Commit: [2/4] cf8fa053602ce1cfac0b6efa67f491688d4f9348 (thuth/qemu-kvm-cs9)
|
||
|
|
|
||
|
|
start.S is currently indented with a mixture of spaces and tabs, which
|
||
|
|
is quite ugly. QEMU coding style says indentation should be 4 spaces,
|
||
|
|
and this is also what we are using in the assembler files in the
|
||
|
|
tests/tcg/s390x/ folder already, so let's adjust start.S accordingly.
