The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.

This patch is for qemu itself.
It test AT_FLAGS and determine whether it is start by binfmt_misc and

This patch is for linux kernel.
It will set the 3rd bit of AT_FLAGS, if P is set for binfmt_misc.
The major concern is that AT_FLAGS is never used, then, should we use it

In fact, currently qemu trys to process the O flag, and it cannot work at all.

hi Peter:
You are right, any additional modification should not affect the previous.
We expect that if this issue could be resolved without code change it's the
best.
it may need to modify both binfmt_misc side to pass more information for flag P
and qemu side to handle it.

The question is: can we have one set of QEMU code that copes correctly
with both 'binfmt_misc with P flag' and 'binfmt_misc without P flag' ?
Your patch makes -P work but breaks some cases without it. That means
it's not backwards compatible with all the existing QEMU installations
and use cases i

Doesn't doing the check like that break execution of a command like
"echo 'MISC_FMT_PRESERVE_ARGV0'" in a chroot environment that isn't
