Subject: [bug report] fsl/qe: setup clock source for TDM mode
Hello Zhao Qiang,
The patch bb8b2062af
Radix guests do normally invalidate process-scoped translations when
a new pid is allocated but migrated guests do not invalidate these so
migrated guests crash sometime, especially easy to reproduce with
migration happening within first 10 seconds after the guest boot start on
the same machine.

In future please tell me why the parameter is unused and when it became
unused.
In this case it was previously used but the

tm_reclaim_thread() doesn't use the parameter anymore, both callers have
to bother getting it as they have no need for a struct thread_info
either.
Just remove it and adjust the callers.

When copying between the vcpu and svcpu, we may get scheduled away onto
a different host CPU which in turn means our svcpu pointer may change.
That means we need to atomically copy to and from the svcpu with preemption
disabled, so that all code around it always sees a coherent state.

Hello Aneesh Kumar K.V,
The patch 1a472c9dba6b: "powerpc/mm/radix: Add tlbflush routines"
from Apr 29, 2016, leads to the following static checker warning:

warn: always true condition '(pid != ~0) => (0-u32max != u64max)'
The recent TLB flush rework broke the build when the Radix MMU is
disabled at build time, eg:
(.text+0x264): undefined reference to `.radix__tlbiel_all'
We could add an empty version, but if we ever called it by accident
that would indicate a bad bug, so add a stub that just WARNs if we do.

Currently the comparison of used < 0 is always false because
uses is a size_t. Fix this by making used a ssize_t type.

Hi,
yesterday I recompiled the kernel on my late 2005 G4 PowerBook, and the
Wifi stopped working. After comparing the configuration is turns out
that a change to a Kconfig condition disabled SSB support which is
necessary for these chips.
The graph of configuration options is quite messy,
