Just a small change to a couple of scripts to go from
#!/usr/bin/env python
to
#!/usr/bin/python
This shouldn't effect anyone, unless they don't install python there.
In preparation for python3, Fedora is doing a big push to change the scripts
to use the system python. This allows developers to put the python3 in
their path without fear of breaking existing scripts.
Now I am pretty sure anyone using python3 for testing purposes will probably
not run any of the scripts I changed, but Fedora has this automated tool
that checks for this stuff so I thought I would try to push it upstream.

This patch implements a checker to detect instructions which
should be paravirtualized instead of direct writing raw instruction.
This patch does rough check so that it doesn't fully cover all cases,
but it can detects most cases of paravirtualization breakage of hand
written assembly codes.

Don't assume that this file has execute permissions. For example, patch(1)
loses that information.

Some versions of ld with --build-id support will crash when using the flag
with a linker script that discards notes. This bites ia64's check-segrel.lds.
The bug is easy to avoid.

advantage of two new GAS directives (.serialize.{data,instruction}).
|

now that there is a fixed GAS.

correctly even on 32-bit hosts. As an added bonus, it's faster,
too. Run "unwcheck" by default, but for now, don't let unwcheck
errors cause the kernel build to fail.

tell the compiler that per-CPU variables can be addressed
with "addl".
On the simulator kernel, this saves about 2776 bytes in the
kernel image. On a zx1 kernel, it saves about 5593 bytes.
As per-CPU variables are used more, these savings will
increase, of course.

this also ensure we really do test the linker which will be
used when building the gate DSO.
|
|
us from building the gate DSO in a way that makes it fit in
<= 1 page. If a fixed linker is available, we do it in this
space-saving way now. Otherwise, we'll do it the old way
(the gate DSO will then take up about 18KB instead of just
~3KB). Thanks to Roland McGrath for making this all work.

the attached patch (against bk-current) fixes a cross
compilation problem by using the target specific objdump
tool instead of the host specific one.
|
|
the kernel. Old gas versions will result in buggy kernels
that will bugcheck all over the place (usually mount() is
the first one to fail).
|
|
the unwind info for consistency (well, just the obvious
stuff, but it's a start).
Fix the couple of bugs that this script uncovered (and work
around one false positive).
