Currently, bpf jit code on powerpc assumes all the bpf functions and
helpers to be kernel text. This is false for kfunc case, as function
addresses are mostly module addresses in that case. Ensure module
addresses are supported to enable kfunc support.
Assume kernel text address for programs with
With module addresses supported, override bpf_jit_supports_kfunc_call()
to enable kfunc support. Module address offsets can be more than 32-bit
long, so override bpf_jit_supports_far_kfunc_call() to enable 64-bit
pointers.

There is no reason to use RESERVEDMEM_OF_DECLARE() as the initialization
hook just saves off the base address and size. Use of
RESERVEDMEM_OF_DECLARE() is reserved for non-driver code and
initialization which must be done early. For qbman, retrieving the
address and size can be done in probe just a

There were not many comments on the previous post last year, so
this a rebase and resend. No significant change to migration patches,
but this rebases on Marc's better fix for cleaning auxinfo. So that
s390 patch is dropped, but added a minor fix for it instead :).
Multi migration works fine. And
Using all prerequisites for the source file results in the build
dying on the second time around with:
gcc: fatal error: cannot specify ‘-o’ with ‘-c’, ‘-S’ or ‘-E’ with multiple
files
This is due to auxinfo.h becoming a prerequisite after the first
build recorded the dependency.
Use the first
Migration files weren't being removed when tests were interrupted.
This improves the situation.

Starting a pipeline of jobs in the background does not seem to have
a simple way to reliably find the pid of a particular process in the
pipeline (because not all processes are started when the shell
continues to execute).
The way PID of QEMU is derived can result in a failure waiting on a

Support multiple migrations by flipping dest file/socket variables to
source after the migration is complete, ready to start again. A new
destination is created if the test outputs the migrate line again.
Test cases may now switch to calling migrate() one or more times.

Using 1 and 2 for source and destination is confusing, particularly
now with multiple migrations that flip between them. Do a rename
pass to tidy things up.

Console output required to support migration becomes quite noisy
when doing lots of migrations. Provide a migrate_quiet() call that
suppresses console output and doesn't log a message.
