Are you guys building SMP kernel for use with AMP? Just wondering why you'd be
using tlbivax at all.

FTRACE_SYSCALLS would create events for each and every system call, even
if it had failed to map the system call's name with it's number. This
resulted in a number of events being created that would not behave as
expected.
This could happen, for example, on architectures who's s

This patch implements the raw syscall tracepoints on PowerPC and exports
them for ftrace syscalls to use.
To minimise reworking existing code, I slightly re-ordered the thread
info flags such that the new TIF_SYSCALL_TRACEPOINT bit would still fit
within the 16 bits of the andi.
From: Ian Munsie
Many system calls are unimplemented and mapped to sys_ni_syscall, but at
boot ftrace would still search through every syscall metadata entry for
a match which wouldn't be there.
This patch adds causes the search to terminate early if the system call
is not mapped.

From: Ian Munsie
Some architectures have unusual symbol names and the generic code to
match the symbol name with the function name for the syscall metadata
will fail. For example, symbols on PPC64 start with a period and the
generic code will fail to match them.
This patch moves the match logic
From: Ian Munsie
Some architectures use non-trivial system call tables and will not work
with the generic arch_syscall_addr code. For example, PowerPC64 uses a
table of twin long longs.
This patch makes the generic arch_syscall_addr weak to allow
architectures with non-trivial system call tables
From: Ian Munsie
With the ftrace events now checking if the syscall_nr is valid upon
initialisation it should no longer be possible to register or unregister
a syscall event without a valid syscall_nr since they should not be
created. This adds a WARN_ON_ONCE in the register and unregister
functi

Hi All,
This is a partial version of my 'ftrace syscalls, PowerPC: Various fixes,

This is reworked http://patchwork.ozlabs.org/patch/71489/
Originally there were 4 questions left:
1. /sys/devices/system/cpu/cpu##/dscr
It is left as is.
2. Out of band method of changing the DSCR:
Introduced new /sys/devices/system/cpu/dscr_default and "dscr_inherit"

For AMP, different kernel instances load into separate memory regions.
Read the start of memory from the device tree and limit the memory to what's
specified in the device tree.

Allow the early debug uart address to be overridden from the kernel
command line.
I would have preferred use the uart's virtual-reg property, but the device
tree hasn't been unflatted yet, and I don't know a reliable way to find it.

This allows independent OS instances to run on separate cores.
