Hi,
I am trying to boot a current 2.6 kernel as a guest under XEN in HVM mode.
With linux-2.6.22.(5) as the guest this works fine but current git kernels
fail very early in the boot process.
The XEN host is a debian kernel with XEN enabled (2.6.18-4-xen-686).
The XEN guest is a vanilla kernel fr

Hi,
I just found this out the hard way:
If a signal handler is registered with the SA_ONSTACK flag the
kernel will try to execute the signal handler on the alternate
stack even if no such stack is registered.
This is an explicit violation of Unix98 and probably Posix.
