Jeff Harris 387719c2ec spi: Fix WARN when removing spi-fsl-spi module
If CPM mode is not used, the fsl_dummy_rx variable is never allocated.  When
the cleanup attempts to free it, the reference count is zero and a WARN is
generated.  The same CPM mode check used in the initialize is applied to the
free as well.

Tested on 2.6.33 with the previous spi_mpc8xxx driver.  The renamed
spi-fsl-spi driver looks to have the same problem.

Darren Hart 9e59e0995a perf tools: Add support for disabling -Werror via WERROR=0
GCC often introduces new warnings with lots of false positives -
breaking -Werror builds. WERROR=0 allows one to build perf without much
fuss - while still encouraging people to send patches to avoid the fuss
of having to type WERROR=0.

Bisecting back to commits that produce a (mostly harmless) warning on
some compilers is more difficult. With WERROR=0 one could bisect without
worrying about harmless warnings.

Arnaldo Carvalho de Melo af52aafad2 perf top: Fix userspace sample addr map offset
The 'perf top' tool came from the kernel where we had each DSO (vmlinux,
modules) loaded just once at a time.

But userspace may have DSOs loaded in multiple addresses (shared
libraries), requiring that we use the just resolved map instead of the
first one found.

Stephane Eranian be96ea8ffa perf symbols: Fix issue with binaries using 16-bytes buildids (v2)
Buildid can vary in size. According to the man page of ld, buildid can
be 160 bits (sha1) or 128 bits (md5, uuid). Perf assumes buildid size of
20 bytes (160 bits) regardless. When dealing with md5 buildids, it would
thus read more than needed and that would cause mismatches and samples
without symbols.

This patch fixes this by taking into account the actual buildid size as
encoded int he section header. The leftover bytes are also cleared.

This second version fixes a minor issue with the memset() base position.

David Ahern 936be50306 perf tool: Fix endianness handling of u32 data in samples
Currently, analyzing PPC data files on x86 the cpu field is always 0 and
the tid and pid are backwards. For example, analyzing a PPC file on PPC
the pid/tid fields show:

        rsyslogd  1210/1212

and analyzing the same PPC file using an x86 perf binary shows:

        rsyslogd  1212/1210

The problem is that the swap_op method for samples is
perf_event__all64_swap which assumes all elements in the sample_data
struct are u64s. cpu, tid and pid are u32s and need to be handled
individually. Given that the swap is done before the sample is parsed,
the simplest solution is to undo the 64-bit swap of those elements when
the sample is parsed and do the proper swap.

The RAW data field is generic and perf cannot have programmatic knowledge
of how to treat that data. Instead a warning is given to the user.

Thanks to Anton Blanchard for providing a data file for a mult-CPU
PPC system so I could verify the fix for the CPU fields.

v3 -> v4:
- fixed use of WARN_ONCE

v2 -> v3:
- used WARN_ONCE for message regarding raw data
- removed struct wrapper around union
- fixed whitespace issues

v1 -> v2:
- added a union for undoing the byte-swap on u64 and redoing swap on
  u32's to address compiler errors (see git commit 65014ab3)

Anton Blanchard 6bb8f311a8 perf sort: Fix symbol sort output by separating unresolved samples by type
I took a profile that suggested 60% of total CPU time was in the
hypervisor:

...
    60.20%  [H] 0x33d43c
     4.43%  [k] ._spin_lock_irqsave
     1.07%  [k] ._spin_lock

Using perf stat to get the user/kernel/hypervisor breakdown contradicted
this.

The problem is we merge all unresolved samples into the one unknown
bucket. If add a comparison by sample type to sort__sym_cmp we get the
real picture:

...
    57.11%  [.] 0x80fbf63c
     4.43%  [k] ._spin_lock_irqsave
     1.07%  [k] ._spin_lock
     0.65%  [H] 0x33d43c

So it was almost all userspace, not hypervisor as the initial profile
suggested.

I found another issue while adding this. Symbol sorting sometimes shows
multiple entries for the unknown bucket:

...
    16.65%  [.] 0x6cd3a8
     7.25%  [.] 0x422460
     5.37%  [.] yylex
     4.79%  [.] malloc
     4.78%  [.] _int_malloc
     4.03%  [.] _int_free
     3.95%  [.] hash_source_code_string
     2.82%  [.] 0x532908
     2.64%  [.] 0x36b538
     0.94%  [H] 0x8000000000e132a4
     0.82%  [H] 0x800000000000e8b0

This happens because we aren't consistent with our sorting. On
one hand we check to see if both symbols match and for two unresolved
samples sym is NULL so we match:

        if (left->ms.sym == right->ms.sym)
                return 0;

On the other hand we use sample IP for unresolved samples when
comparing against a symbol:

       ip_l = left->ms.sym ? left->ms.sym->start : left->ip;
       ip_r = right->ms.sym ? right->ms.sym->start : right->ip;

This means unresolved samples end up spread across the rbtree and we
can't merge them all.

If we use cmp_null all unresolved samples will end up in the one bucket
and the output makes more sense:

...
    39.12%  [.] 0x36b538
     5.37%  [.] yylex
     4.79%  [.] malloc
     4.78%  [.] _int_malloc
     4.03%  [.] _int_free
     3.95%  [.] hash_source_code_string
     2.26%  [H] 0x800000000000e8b0

Anton Blanchard 6a0e55d85b perf symbols: Synthesize anonymous mmap events
perf_event__synthesize_mmap_events does not create anonymous mmap events
even though the kernel does. As a result an already running application
with dynamically created code will not get profiled - all samples end up
in the unknown bucket.

This patch skips any entries with '[' in the name to avoid adding events
for special regions (eg the vsyscall page). All other executable mmaps
are assumed to be anonymous and an event is synthesized.

David Ahern 764e16a30a perf record: Create events initially disabled and enable after init
perf-record currently creates events enabled. When doing a system wide
collection (-a arg) this causes data collection for perf's
initialization activities -- eg., perf_event__synthesize_threads().

For some events (e.g., context switch S/W event or tracepoints like
syscalls) perf's initialization causes a lot of events to be captured
frequently generating "Check IO/CPU overload!" warnings on larger
systems (e.g., 2 socket, quad core, hyperthreading).

perf's initialization phase can be skipped by creating events
disabled and then enabling them once the initialization is done.

Anton Blanchard 3f5a42722b perf symbols: /proc/kallsyms does not sort module symbols
kallsyms__parse assumes that /proc/kallsyms is sorted and sets the end
of the previous symbol to the start of the current one.

Unfortunately module symbols are not sorted, eg:

ffffffffa0081f30 t e1000_clean_rx_irq   [e1000e]
ffffffffa00817a0 t e1000_alloc_rx_buffers       [e1000e]

Some symbols end up with a negative length and others have a length
larger than they should. This results in confusing perf output.

We already have a function to fixup the end of zero length symbols so
use that instead.

Masami Hiramatsu f66fedcb72 perf probe: Fix regression of variable finder
Fix to call convert_variable() if previous call does not fail.

To call convert_variable, it ensures "ret" is 0. However, since
"ret" has the return value of synthesize_perf_probe_arg() which
always returns positive value if it succeeded, perf probe doesn't
call convert_variable(). This will cause a SEGV when we add an
event with arguments.

This has to be fixed as it ensures "ret" is greater than 0
(or not negative).

This regression has been introduced by my previous patch, f182e3e1.

Thomas Pfaff 362e4e49ab ALSA: usb-audio - clear chip->probing on error exit
The Terratec Aureon 5.1 USB sound card support is broken since kernel
2.6.39.
2.6.39 introduced power management support for USB sound cards that added
a probing flag in struct snd_usb_audio.

During the probe of the card it gives following error message :

usb 7-2: new full speed USB device number 2 using uhci_hcd
cannot find UAC_HEADER
snd-usb-audio: probe of 7-2:1.3 failed with error -5
input: USB Audio as

on usb-0000:00:1d.1-2/input3

I can not comment about that "cannot find UAC_HEADER" error, but until
2.6.38 the card worked anyway.
With 2.6.39 chip->probing remains 1 on error exit, and any later ioctl
stops in snd_usb_autoresume with -ENODEV.

Jarkko Nikula 34c869855a ASoC: omap-mcbsp: Do not attempt to change DAI sysclk if stream is active
Attempt to change McBSP CLKS source while another stream is active is not
safe after commit d135865 ("OMAP: McBSP: implement functional clock
switching via clock framework") in 2.6.37.

CLKS parent clock switching using clock framework have to idle the McBSP
before switching and then activate it again. This short break can cause a
DMA transaction error to already running stream which halts and recovers
only by closing and restarting the stream.

This goes more fatal after commit e2fa61d ("OMAP3: l3: Introduce
l3-interconnect error handling driver") in 2.6.39 where l3 driver detects a
severe timeout error and does BUG_ON().

Fix this by not changing any configuration in omap_mcbsp_dai_set_dai_sysclk
if the McBSP is already active. This test should have been here just from
the beginning anyway.

Peter Huewe 6b07d30aca TPM: Call tpm_transmit with correct size
This patch changes the call of tpm_transmit by supplying the size of the
userspace buffer instead of TPM_BUFSIZE.

This got assigned CVE-2011-1161.

[The first hunk didn't make sense given one could expect
 way less data than TPM_BUFSIZE, so added tpm_transmit boundary
 check over bufsiz instead
 The last parameter of tpm_transmit() reflects the amount
 of data expected from the device, and not the buffer size
 being supplied to it. It isn't ideal to parse it directly,
 so we just set it to the maximum the input buffer can handle
 and let the userspace API to do such job.]

Geert Uytterhoeven 5ce5ed3593 TPM: TCG_ATMEL should depend on HAS_IOPORT
On m68k, I get:

drivers/char/tpm/tpm_atmel.h: In function ‘atmel_get_base_addr’:
drivers/char/tpm/tpm_atmel.h:129: error: implicit declaration of function ‘ioport_map’
drivers/char/tpm/tpm_atmel.h:129: warning: return makes pointer from integer without a cast

The code in tpm_atmel.h supports PPC64 (using the device tree and ioremap())
and "anything else" (using ioport_map()). However, ioportmap() is only
available on platforms that set HAS_IOPORT.

Although PC64 seems to have HAS_IOPORT, a "depends on HAS_IOPORT" should work,
but I think it's better to expose the special PPC64 handling explicit using
"depends on PPC64 || HAS_IOPORT".

Geert Uytterhoeven a7f4d00a82 zorro: Defer device_register() until all devices have been identified
As the Amiga Zorro II address space is limited to 8.5 MiB and Zorro
devices can contain only one BAR, several Amiga Zorro II expansion
boards (mainly graphics cards) contain multiple Zorro devices: a small
one for the control registers and one (or more) for the graphics memory.

The conversion of cirrusfb to the new driver framework introduced a
regression: the driver contains a zorro_driver for the first Zorro
device, and uses the (old) zorro_find_device() call to find the second
Zorro device.

However, as the Zorro core calls device_register() as soon as a Zorro
device is identified, it may not have identified the second Zorro device
belonging to the same physical Zorro expansion card.  Hence cirrusfb
could no longer find the second part of the Picasso II graphics card,
causing a NULL pointer dereference.

Defer the registration of Zorro devices with the driver framework until
all Zorro devices have been identified to fix this.

Note that the alternative solution (modifying cirrusfb to register a
zorro_driver for all Zorro devices belonging to a graphics card, instead
of only for the first one, and adding a synchronization mechanism to
defer initialization until all have been found), is not an option, as on
some cards one device may be optional (e.g.  the second bank of 2 MiB of
graphics memory on the Picasso IV in Zorro II mode).

Mark Salyzyn 24926dadc4 [SCSI] libsas: fix failure to revalidate domain for anything but the first expander child.
In an enclosure model where there are chaining expanders to a large body
of storage, it was discovered that libsas, responding to a broadcast
event change, would only revalidate the domain of first child expander
in the list.

The issue is that the pointer value to the discovered source device was
used to break out of the loop, rather than the content of the pointer.

This still remains non-compliant as the revalidate domain code is
supposed to loop through all child expanders, and not stop at the first
one it finds that reports a change count. However, the design of this
routine does not allow multiple device discoveries and that would be a
more complicated set of patches reserved for another day. We are fixing
the glaring bug rather than refactoring the code.
