ptrace flags
PPC_PTRACE_GETHWDBGINFO, PPC_PTRACE_SETHWDEBUG and PPC_PTRACE_DELHWDEBUG are
PowerPC specific ptrace flags that use the watchpoint register. While they are
targeted primarily towards BookE users, user-space applications such as GDB
have started using them for BookS too. This patch enables the use of generic
hardware breakpoint interfaces for these new flags.
Apart from the usual benefits of using generic hw-breakpoint interfaces, these
changes allow debuggers (such as GDB) to use a common set of ptrace flags for
their watchpoint needs and allow more precise breakpoint specification (length
of the variable can be specified).
Mikey added: rebased and added dbginfo.features around #ifdef

.......
The reason is that the back chain of c00000017666fe30
(ret_from_kernel_thread) contains some invalid value, which might form a
loop.

OPAL provides the firmware base/entry in registers at boot time
for debugging purposes. We had a bug in the code trying to stash
these into the appropriate kernel globals (a line of code was
probably dropped by accident back when this was merged)

The function initialize_flash_pde_data is only called four times. All four
calls are in the function rtas_flash_init, and on the failure of any of the
calls, remove_flash_pde is called on the third argument of each of the
calls. There is thus no need for initialize_flash_pde_data to call
remove_flash_pde on the same argument. remove_flash_pde kfrees the data
field of its argument, and does not clear that field, so this amounts ot a
possible double free.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

There're couples of functions defined to print debugging messages
during initializing P7IOC. However, we got bogus output from those
functions like pe_info(). The problem here is that the message
level (the first parameter to printk()) isn't printable and that
caused the bogus output.
The patch fixes the issue by merging __pe_printk() to the macro
define_pe_printk_level() so that we can pass the message level
directly to printk().

It is possible to configure a kernel which has xmon enabled, but has no
udbg backend to provide IO. This can make xmon rather confusing, as it
produces no output, blocks for two seconds, and then returns.
As a last resort we can instead try to printk(), which may deadlock or
otherwise crash, but tries quite hard not to.

Currently xmon_depth_to_print is static and global, but it's only
ever used in xmon_show_stack().
At least with a modern compiler it's inlined, so there's no point
in it being static, we could #define it but it's only used in one
place.
By reworking the logic we can drop count and just decrement the
max value as a loop counter. Also switch to a while loop so we
actually print no more than 64 frames as you'd expect based on the
variable name.

We have two #defines that rename scanhex() and skipbl() to
xmon_scanhex() and xmon_skipbl() - but no one ever uses those
names.
So the only effect is to rename the actual symbols in the generated
code, and AFACIS there is no reason to do that, so drop them.

The routines in start.c are only ever called from nonstdio.c, so if we
move them in there they can become static which is nice.
I suspect the idea behind the separation was that start.c could be
replaced in order to build xmon in userland. If anyone still cares about
doing that we could handle that with an ifdef or two.

It looks like xmon_expect() was used for doing xmon over a modem (!?),
that code was dropped in 2005 in commit 51d3082 "Unify udbg (#2)".
Once xmon_expect() is gone xmon_read_poll() is unused, drop it too.

With CONFIG_PARAVIRT=y and CONFIG_TRANSPARENT_HUGEPAGE=n, the build breaks
because set_pmd_at() is undeclared:
mm/memory.c: In function 'do_pmd_numa_page':
mm/memory.c:3520: error: implicit declaration of function 'set_pmd_at'
mm/mprotect.c: In function 'change_pmd_protnuma':
mm/mprotect.c:120: error: implicit declaration of function 'set_pmd_at'
This is because paravirt defines set_pmd_at() only when
CONFIG_TRANSPARENT_HUGEPAGE=y and such a restriction is unneeded. The
fix is to define it for all CONFIG_PARAVIRT configurations.

Optimize RAID6 recovery functions to take advantage of
the 256-bit YMM integer instructions introduced in AVX2.
The patch was tested and benchmarked before submission.
However hardware is not yet released so benchmark numbers
cannot be reported.

This function is used by sparc, powerpc tile and arm64 for compat support.
The patch adds a generic implementation with a wrapper for PowerPC to do
the u32->int sign extension.
The reason for a single patch covering powerpc, tile, sparc and arm64 is
to keep it bisectable, otherwise kernel building may fail with mismatched
function declarations.

Currently the __define_initcall() macro takes three arguments, fn, id and
level. The level argument is exactly the same as the id argument but
wrapped in quotes. To overcome this need to specify three arguments to
the __define_initcall macro, where one argument is the stringification of
another, we can just use the stringification macro instead.

patch(1) doesn't create zero-length files, so my kernel didn't compile.
Put something in these files so patch(1) actually creates them.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace changes from Eric Biederman:
"While small this set of changes is very significant with respect to
containers in general and user namespaces in particular. The user
space interface is now complete.
This set of changes adds support for unprivileged users to create user
namespaces and as a user namespace root to create other namespaces.
The tyranny of supporting suid root preventing unprivileged users from
using cool new kernel features is broken.
This set of changes completes the work on setns, adding support for
the pid, user, mount namespaces.
This set of changes includes a bunch of basic pid namespace
cleanups/simplifications. Of particular significance is the rework of
the pid namespace cleanup so it no longer requires sending out
tendrils into all kinds of unexpected cleanup paths for operation. At
least one case of broken error handling is fixed by this cleanup.
The files under /proc/<pid>/ns/ have been converted from regular files
to magic symlinks which prevents incorrect caching by the VFS,
ensuring the files always refer to the namespace the process is
currently using and ensuring that the ptrace_mayaccess permission
checks are always applied.
The files under /proc/<pid>/ns/ have been given stable inode numbers
so it is now possible to see if different processes share the same
namespaces.
Through the David Miller's net tree are changes to relax many of the
permission checks in the networking stack to allowing the user
namespace root to usefully use the networking stack. Similar changes
for the mount namespace and the pid namespace are coming through my
tree.
Two small changes to add user namespace support were commited here adn
in David Miller's -net tree so that I could complete the work on the
/proc/<pid>/ns/ files in this tree.
Work remains to make it safe to build user namespaces and 9p, afs,
ceph, cifs, coda, gfs2, ncpfs, nfs, nfsd, ocfs2, and xfs so the
Kconfig guard remains in place preventing that user namespaces from
being built when any of those filesystems are enabled.
Future design work remains to allow root users outside of the initial
user namespace to mount more than just /proc and /sys."

The expressions tsk->nsproxy->pid_ns and task_active_pid_ns
aka ns_of_pid(task_pid(tsk)) should have the same number of
cache line misses with the practical difference that
ns_of_pid(task_pid(tsk)) is released later in a processes life.
Furthermore by using task_active_pid_ns it becomes trivial
to write an unshare implementation for the the pid namespace.
So I have used task_active_pid_ns everywhere I can.
In fork since the pid has not yet been attached to the
process I use ns_of_pid, to achieve the same effect.

The kbuild test robot <fengguang.wu@intel.com> report the following error
when building mips with user namespace support enabled.
All error/warnings:
arch/mips/kernel/mips-mt-fpaff.c: In function 'check_same_owner':
arch/mips/kernel/mips-mt-fpaff.c:53:22: error: invalid operands to binary == (have 'kuid_t' and 'kuid_t')
arch/mips/kernel/mips-mt-fpaff.c:54:15: error: invalid operands to binary == (have 'kuid_t' and 'kuid_t')
Replace "a == b" with uid_eq(a, b) removes this error and allows the
code to work with user namespaces enabled.

Pull m68knommu updates from Greg Ungerer:
"This one has a major restructuring of the non-mmu 68000 support.
It merges all the related SoC types that use the original 68000 cpu
core internally so they can share the same core code. It also allows
for supporting the original stand alone 68000 cpu in its own right.
There is also a generalization of the clock support of the ColdFire
parts, some merging of common ColdFire code, and a couple of bug fixes
as well."

The existing clk.c code for ColdFire CPUs has one set of functions to
support those CPU types that have selectable clocks (those with a PPMCR
register), and a duplicate simpler set for those with static clocks.
Modify the clk.c code so there is just one set of support functions. All
CPU types now define a list of clocks (in "struct clk"s), so we only need
a single set of clock functions.
