Helge Deller a0ffa8f06f Revert "parisc: implement full version of access_ok()"
This reverts commit 63379c1353.

It broke userspace and adding more checking is not needed.
Even checking if a syscall would access memory in page zero doesn't
makes sense since it may lead to some syscalls returning -EFAULT
where we would return other error codes on other platforms.
In summary, just drop this change and return to always return 1.

 "A series of patches that fix compilation on non-x86 archs.

  While most of them are just build fixes, there are some fixes for real
  bugs, as there are a number of drivers using dynamic stack allocation.
  A few of those might be considered a security risk, if the i2c-dev
  module is loaded, as someone could be sending very long I2C data that
  could potentially overflow the Kernel stack.  Ok, as using /dev/i2c-*
  devnodes usually requires root on usual distros, and exploiting it
  would require a DVB board or USB stick, the risk is not high"

 "This series include:
   - a new Remote Controller driver for ST SoC with the corresponding DT

   - a new frontend (cx24117)

   - some improvements on buffer allocation at VB2 core
   - usual driver fixes and improvements

  PS this time, we have a smaller number of patches.  While it is hard
  to pinpoint to the reasons, I believe that it is mainly due to:

   1) there are several patch series ready, but depending on DT review.
      I decided to grant some extra time for DT maintainers to look on
      it, as they're expecting to have more time with the changes agreed
      during ARM mini-summit and KS.  If they can't review in time for
      3.14, I'll review myself and apply for the next merge window.

   2) I suspect that having both LinuxCon EU and LinuxCon NA happening
      during the same merge window affected the development
      productivity, as several core media developers participated on
      both events"

 "Following up on last week's discussion, here's my part of the EDAC
  pile, highlights in the signed tag.

  The last two patches have a date from just now because I've just
  applied them to the tree after Johannes sent them to me earlier.  I
  decided to forward them now because they're trivial.

  There's a third one for MPC85xx which adds PCIe error interrupt
  support but since it is not so trivial and hasn't seen any linux-next
  time, I'm deferring it to 3.14

  EDAC update highlights:
   - Support for Calxeda ECX-2000 memory controller, from Robert Richter
   - Misc Calxeda Highbank drivers and EDAC core cleanups, from Rob
     Herring and Robert Richter
   - New maintainer for Freescale's MPC85xx EDAC driver: Johannes
     Thumshirn"

This reverts commit 69f0554ec2.

This patch breaks randconfig on at least the x86-64 architecture, and
most likely on others.  There is work underway to support uncompressed
kernels in a generic way, but it looks like it will amount to
rewriting the support from scratch; see the LKML thread in the Link:
for info.

Therefore, revert this change and wait for the fix.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions

Jean Delvare 487722cf2d watchdog: Get rid of MODULE_ALIAS_MISCDEV statements
I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.

Either the device is enumerated and the driver already has a module
alias (e.g. PCI, USB etc.) that will get the right driver loaded
automatically.

Or the device is not enumerated and loading its driver will lead to
more or less intrusive hardware poking. Such hardware poking should be
limited to a bare minimum, so the user should really decide which
drivers should be tried and in what order. Trying them all in
arbitrary order can't do any good.

On top of that, loading that many drivers at once bloats the kernel
log. Also many drivers will stay loaded afterward, bloating the output
of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
loaded as a dependency) can't even be unloaded!

If defining char-major-10-130 is needed then it should happen in
user-space.

Sachin Kamat 85eee81922 watchdog: Remove redundant of_match_ptr
of_match_ptr() is a macro used to avoid undefined reference error if
CONFIG_OF is used to selectively compile in or out the
data structure. It is defined as follows:

#ifdef CONFIG_OF
#define of_match_ptr(ptr) ptr
#else
#define of_match_ptr(ptr) NULL
#endif

In the case of this series, none of the drivers use CONFIG_OF macro to
compile out the data structure (i.e., the data structure is always
defined).
Hence the use of of_match_ptr() does not make any sense. Thus removing
it to make the code look simpler for readability.

The rest is just clean up.  get_user() actually returns zero on success
and -EFAULT on error so we can preserve the error code.  The
timeout_to_regval() function returns -EINVAL on failure, but we can
propogate that back instead of hardcoding -EINVAL ourselves.

The dw_wdt only provides PM_SLEEP operations, so convert the driver
to use SIMPLE_DEV_PM_OPS instead of populating the struct manually.
This has the added effect of simplifying the CONFIG_PM ifdefs.

Andreas Werner 5e47eec004 i2c: i2c-eg20t: do not print error message in syslog if no ACK received
Using the i2c-eg20t driver and call i2cdetect or probe on the bus,
the driver will print a lot of error messages if there was no ACK
received.

i2cdetect normally print a table with all the available devices. If there
is no device on the address, the table will be empty.
Currently with the i2c-eg20t driver, the table is not visible because
the error messages destroy the table.

Error message: pch_i2c_getack return -71

This patch prevent the driver to print the messages to syslog.
The pch_i2c_wait_for_check_xfer function is the only one who is
calling pch_i2c_getack, so we can delete the function and add the
read to pch_i2c_wait_for_check_xfer.
If no ACK is received, the Message will be printed as a dbg
message.

Fixed print message to be a one liner so we can grep for the
error message.

Tested on Intel Atom E6xx and Eg20t Chipset.

Yann Droneaud f21519b23c IB/core: extended command: an improved infrastructure for uverbs commands
Commit 400dbc9658 ("IB/core: Infrastructure for extensible uverbs
commands") added an infrastructure for extensible uverbs commands
while later commit 436f2ad05a ("IB/core: Export ib_create/destroy_flow
through uverbs") exported ib_create_flow()/ib_destroy_flow() functions
using this new infrastructure.

According to the commit 400dbc9658, the purpose of this
infrastructure is to support passing around provider (eg. hardware)
specific buffers when userspace issue commands to the kernel, so that
it would be possible to extend uverbs (eg. core) buffers independently
from the provider buffers.

But the new kernel command function prototypes were not modified to
take advantage of this extension. This issue was exposed by Roland
Dreier in a previous review[1].

So the following patch is an attempt to a revised extensible command
infrastructure.

This improved extensible command infrastructure distinguish between
core (eg. legacy)'s command/response buffers from provider
(eg. hardware)'s command/response buffers: each extended command
implementing function is given a struct ib_udata to hold core
(eg. uverbs) input and output buffers, and another struct ib_udata to
hold the hw (eg. provider) input and output buffers.

Having those buffers identified separately make it easier to increase
one buffer to support extension without having to add some code to
guess the exact size of each command/response parts: This should make
the extended functions more reliable.

Additionally, instead of relying on command identifier being greater
than IB_USER_VERBS_CMD_THRESHOLD, the proposed infrastructure rely on
unused bits in command field: on the 32 bits provided by command
field, only 6 bits are really needed to encode the identifier of
commands currently supported by the kernel. (Even using only 6 bits
leaves room for about 23 new commands).

So this patch makes use of some high order bits in command field to
store flags, leaving enough room for more command identifiers than one
will ever need (eg. 256).

The new flags are used to specify if the command should be processed
as an extended one or a legacy one. While designing the new command
format, care was taken to make usage of flags itself extensible.

Using high order bits of the commands field ensure that newer
libibverbs on older kernel will properly fail when trying to call
extended commands. On the other hand, older libibverbs on newer kernel
will never be able to issue calls to extended commands.

The extended command header includes the optional response pointer so
that output buffer length and output buffer pointer are located
together in the command, allowing proper parameters checking. This
should make implementing functions easier and safer.

Additionally the extended header ensure 64bits alignment, while making
all sizes multiple of 8 bytes, extending the maximum buffer size:

                             legacy      extended

   Maximum command buffer:  256KBytes   1024KBytes (512KBytes + 512KBytes)
  Maximum response buffer:  256KBytes   1024KBytes (512KBytes + 512KBytes)

For the purpose of doing proper buffer size accounting, the headers
size are no more taken in account in "in_words".

One of the odds of the current extensible infrastructure, reading
twice the "legacy" command header, is fixed by removing the "legacy"
command header from the extended command header: they are processed as
two different parts of the command: memory is read once and
information are not duplicated: it's making clear that's an extended
command scheme and not a different command scheme.

The proposed scheme will format input (command) and output (response)
buffers this way:

- command:

  legacy header +
  extended header +
  command data (core + hw):

    +----------------------------------------+
    | flags     |   00      00    |  command |
    |        in_words    |   out_words       |
    +----------------------------------------+
    |                 response               |
    |                 response               |
    | provider_in_words | provider_out_words |
    |                 padding                |
    +----------------------------------------+
    |                                        |
    .              <uverbs input>            .
    .              (in_words * 8)            .
    |                                        |
    +----------------------------------------+
    |                                        |
    .             <provider input>           .
    .          (provider_in_words * 8)       .
    |                                        |
    +----------------------------------------+

- response, if present:

    +----------------------------------------+
    |                                        |
    .          <uverbs output space>         .
    .             (out_words * 8)            .
    |                                        |
    +----------------------------------------+
    |                                        |
    .         <provider output space>        .
    .         (provider_out_words * 8)       .
    |                                        |
    +----------------------------------------+

The overall design is to ensure that the extensible infrastructure is
itself extensible while begin more reliable with more input and bound
checking.

Note:

The unused field in the extended header would be perfect candidate to
hold the command "comp_mask" (eg. bit field used to handle
compatibility).  This was suggested by Roland Dreier in a previous
review[2].  But "comp_mask" field is likely to be present in the uverb
input and/or provider input, likewise for the response, as noted by
Matan Barak[3], so it doesn't make sense to put "comp_mask" in the
header.
