Subject: [PATCH] target-arm: linux-user: no tb_flush on reset
|
|
|
|
When running automoc4 as linux-user guest program, it segfaults right after
|
|
it creates a thread. Bisecting pointed to commit a84fac1426 which introduces
|
|
tb_flush on reset.
|
|
|
|
So something in our thread creation is broken. But for now, let's revert the
|
|
change to at least get a working build again.

[AF: Rebased, fixed typo]
