Subject: helper_syscall x86_64: clear exception_is_int
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=56bf1c4985fb9ad24642f176cc40db0eb4f3dc31;p=qemu.git

helper_syscall x86_64: clear exception_is_int

The exception_is_int flag may be set on entry to helper_syscall,
e.g. after a prior interrupt that has returned, and processing
EXCP_SYSCALL as an interrupt causes it to fail so clear this flag.
