RH-Commit: [3/4] c2f69ce5998861fe20b799bf0113def8cf0cd128 (thuth/qemu-kvm-cs9)
|
|
|
|
Providing the space of a stack frame is the duty of the caller,
|
|
so we should reserve 160 bytes before jumping into the main function.
|
|
Otherwise the main() function might write past the stack array.
|
|
|
|
While we're at it, add a proper STACK_SIZE macro for the stack size
|
|
instead of using magic numbers (this is also required for the following
|
|
patch).
