linux-stable.git/arch/unicore32, branch v3.8

ARCH: drivers remove __dev* attributes.

2013-01-03T23:57:13+00:00

This fixes up all of the smaller arches that had __dev* markings for
their platform-specific drivers.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

  Note that there are several conflicts between "unify

  resolution is trivial - just remove definitions of SS_ONSTACK and
  SS_DISABLED from arch/*/uapi/asm/signal.h; they are all identical and
  include/uapi/linux/signal.h contains the unified variant."

Bury the conditionals from kernel_thread/kernel_execve series

All architectures have
	CONFIG_GENERIC_KERNEL_THREAD
	CONFIG_GENERIC_KERNEL_EXECVE
	__ARCH_WANT_SYS_EXECVE
None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers
of kernel_execve() (which is a trivial wrapper for do_execve() now) left.
Kill the conditionals and make both callers use do_execve().

In commit d0a21265dfb5fa8a David Rientjes unified various archs'
module_alloc implementation (including x86) and removed the graduitous
shortcut for size == 0.

Then, in commit de7d2b567d040e3b, Joe Perches added a warning for
zero-length vmallocs, which can happen without kallsyms on modules
with no init sections (eg. zlib_deflate).

Fix this once and for all; the module code has to handle zero length
anyway, so get it right at the caller and remove the now-gratuitous
checks within the arch-specific module_alloc implementations.

Pull big execve/kernel_thread/fork unification series from Al Viro:
 "All architectures are converted to new model.  Quite a bit of that
  stuff is actually shared with architecture trees; in such cases it's
  literally shared branch pulled by both, not a cherry-pick.

  A lot of ugliness and black magic is gone (-3KLoC total in this one):

   - kernel_thread()/kernel_execve()/sys_execve() redesign.

     We don't do syscalls from kernel anymore for either kernel_thread()
     or kernel_execve():

     kernel_thread() is essentially clone(2) with callback run before we
     return to userland, the callbacks either never return or do
     successful do_execve() before returning.

     kernel_execve() is a wrapper for do_execve() - it doesn't need to
     do transition to user mode anymore.

     As a result kernel_thread() and kernel_execve() are
     arch-independent now - they live in kernel/fork.c and fs/exec.c
     resp.  sys_execve() is also in fs/exec.c and it's completely
     architecture-independent.

   - daemonize() is gone, along with its parts in fs/*.c

   - struct pt_regs * is no longer passed to do_fork/copy_process/
     copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump.

   - sys_fork()/sys_vfork()/sys_clone() unified; some architectures
     still need wrappers (ones with callee-saved registers not saved in
     pt_regs on syscall entry), but the main part of those suckers is in
     kernel/fork.c now."

Main changes:

* ftrace enhancements and fixes from Steve Rostedt.

* uprobes fixes, cleanups and preparation for the ARM port from Oleg
Nesterov.

* UAPI fixes, from David Howels - prepares the arch/x86 UAPI
transition

* Separate perf tests into multiple objects, one per test, from Jiri
Olsa.

* Make hardware event translations available in sysfs, from Jiri
Olsa.

* Fixes to /proc/pid/maps parsing, preparatory to supporting data
maps, from Namhyung Kim

* Implement ui_progress for GTK, from Namhyung Kim

* Add framework for automated perf_event_attr tests, where tools with
different command line options will be run from a 'perf test', via
python glue, and the perf syscall will be intercepted to verify
that the perf_event_attr fields set by the tool are those expected,
from Jiri Olsa

* Add a 'link' method for hists, so that we can have the leader with
buckets for all the entries in all the hists. This new method is
now used in the default 'diff' output, making the sum of the
'baseline' column be 100%, eliminating blind spots.

* libtraceevent fixes for compiler warnings trying to make perf it
build on some distros, like fedora 14, 32-bit, some of the warnings
really pointed to real bugs.

* Add a browser for 'perf script' and make it available from the
report and annotate browsers. It does filtering to find the
scripts that handle events found in the perf.data file used. From
Feng Tang

* perf inject changes to allow showing where a task sleeps, from
Andrew Vagin.

* Makefile improvements from Namhyung Kim.

* Add --pre and --post command hooks in 'stat', from Peter Zijlstra.

* Don't stop synthesizing threads when one vanishes, this is for the
existing threads when we start a tool like trace.

* Use sched:sched_stat_runtime to provide a thread summary, this
produces the same output as the 'trace summary' subcommand of
tglx's original "trace" tool.

* Support interrupted syscalls in 'trace'

* Add an event duration column and filter in 'trace'.

* There are references to the man pages in some tools, so try to
build Documentation when installing, warning the user if that is
not possible, from Borislav Petkov.

* Give user better message if precise is not supported, from David
Ahern.

* Try to find cross-built objdump path by using the session
environment information in the perf.data file header, from Irina
Tirdea, original patch and idea by Namhyung Kim.

* Diplays more output on features check for make V=1, so that one can
figure out what is happening by looking at gcc output, etc. From
Jiri Olsa.

* Add on_exit implementation for systems without one, e.g. Android,
from Bernhard Rosenkraenzer.

* Only process events for vcpus of interest, helps handling large
number of events, from David Ahern.

* Cross compilation fixes for Android, from Irina Tirdea.

* Add documentation on compiling for Android, from Irina Tirdea.

* perf diff improvements from Jiri Olsa.

* Target (task/user/cpu/syswide) handling improvements, from Namhyung
Kim.

* Add support in 'trace' for tracing workload given by command line,
from Namhyung Kim.

Pull driver core updates from Greg Kroah-Hartman:
 "Here's the large driver core updates for 3.8-rc1.

  The biggest thing here is the various __dev* marking removals.  This
  is going to be a pain for the merge with different subsystem trees, I
  know, but all of the patches included here have been ACKed by their
  various subsystem maintainers, as they wanted them to go through here.

  If this is too much of a pain, I can pull all of them out of this tree
  and just send you one with the other fixes/updates and then, after
  3.8-rc1 is out, do the rest of the removals to ensure we catch them
  all, it's up to you.  The merges should all be trivial, and Stephen
  has been doing them all in linux-next for a few weeks now quite
  easily.

  Other than the __dev* marking removals, there's nothing major here,
  some firmware loading updates and other minor things in the driver
  core.

  All of these have (much to Stephen's annoyance), been in linux-next
  for a while.
