This code can never be executed as it is only built when
CONFIG_PPC_E500MC is unset, but the only CPUs that have CPU_FTR_L2CSR
require CONFIG_PPC_E500MC and do not have the MSR/HID0-based nap
mechanism that this file uses.

OK, sounds good to me.
MTD folks: any objections to this process? If not, is this patch good to
go in, or any changes we should make?
Cheers,

Check that a syscall made during an active transaction will fail with
the correct failure code and that one made during a suspended
transaction will succeed.

v2:
Further testing has shown that the success or failure of the transactions was
affected by minor changes
This patch changes the syscall handler to doom (tabort) active
transactions when a syscall is made and return immediately without
performing the syscall.
Currently, the system call instruction automatically suspends an
active transaction which causes side effects to persist when an active
transact
See the first patch for a description of the reasoning behind this
change.
This set includes the change, a kernel selftest for it and
some slight refactoring of the selftest code.

Patch 1/4: powerpc/tm: Abort syscalls in active transactions
Use "TABORT()" macro to allow building on version
Move get_auxv_entry() from pmu/lib.c up to harness.c in order to make

I've been looking at this patch series for a while now, and I now
believe it's ready on the PowerPC side.
I was originally concerned that it would break odd corner cases,
particularly where similar code appears (namely kernel/pci_hotplug.c and
kernel/pci_of_scan.c). However, upon further examinati

Hi Peter,
As you are very aware, I think, power has some odd NUMA topologies (and
changes to the those topologies) at run-time. In particular, we can see
a topology at boot:
Node 0: all Cpus
Node 7: no cpus
Then we get a notification from the hypervisor that a core (or two) have
moved from node

I am working on a ppc440gx platform and came across ppc44x_idle()
function. the actual requirement is to enable WAIT_STATE Enable bit
(MSR_WE) and External Interrupt enable bit (MSR_EE) on MSR. But for
ppc440, i see that MSR_DE bit (Debug Interrupt Enable) is also
enabled.
Any idea why MSR_DE enab
