The sdio func device is added to the driver model after the card
device.

This means the sdio func device will be suspend before the card device
and thus resumed after. The consequence are the mmc core don't
explicity need to protect itself from receiving sdio requests in
suspended state. Instead that can be handled from the sdio bus, which
is thus invokes the PM callbacks instead of old dummy function.

In the case were the sdio func driver don't implement the PM callbacks
the mmc core will in the early phase of system suspend, remove the
card from the driver model and thus power off it.

The error is due to an invalid value in CSD register of a specific 2GB
micro SD card. The CSD version of this card is 1.0 but the TACC field
has the invalid value 0.

cid:0000005553442020000000000000583f

preferred_erase_size:4194304
scr:0225000000000000
serial:0x00000000
type:SD

Since the kernel is making use of this TACC field to calculate the SD
card timeout, an invalid value 0 leads to a warning at
mxs_ns_to_ssp_ticks() and later the following misleading error message
appears in a loop:

mxs-mmc 80010000.ssp: card claims to support voltages below defined range
mxs-mmc 80010000.ssp: no support for card's volts
mmc0: error -22 whilst initialising MMC card

This error is only found on this 2GB SD card on mxs platform.
On x86 this card works without any problems.

The following patch based on the work of Peter Chan and Otavio Salvador.
It catches the case that the determined timeout is still 0 and sets it
to a valid value.

In the current version, when using perf record, if something goes
wrong in tools/perf/builtin-record.c:375
  session = perf_session__new(file, false, NULL);

The error message:
"Not enough memory for reading per file header"

is issued. This error message seems to be outdated and is not very
helpful. This patch proposes to replace this error message by
"Perf session creation failed"

I believe this issue has been brought to lkml:
https://lkml.org/lkml/2014/2/24/458
although this patch only tackles a (small) part of the issue.

Additionnaly, this patch improves error reporting in
tools/perf/util/data.c open_file_write.

Currently, if the call to open fails, the user is unaware of it.
This patch logs the error, before returning the error code to
the caller.

In this case symbol values should be adjusted the same way as for executables,

Every event in the perf-kvm has a 'stats' structure, which contains
max/min/average/etc times of handling this event.
The problem is that the 'perf-kvm stat report' command always shows
that 'min time' is 0us for every event. Example:

 # perf kvm stat report

 Analyze events for all VCPUs:

    VM-EXIT    Samples  Samples%     Time%   Min Time   Max Time Avg time
  [..]
  0xB2 MSCH         12     0.07%     0.00%        0us        8us 7.31us ( +-   2.11% )
  0xB2 CHSC         12     0.07%     0.00%        0us       18us 9.39us ( +-   9.49% )
  0xB2 STPX          8     0.05%     0.00%        0us        2us 1.88us ( +-   7.18% )

  [..]

This happens because the 'stats' structure is not initialized and
stats->min equals to 0. Lets initialize the structure for every
event after its allocation using init_stats() function. This initializes
stats->min to -1 and makes 'Min time' statistics counting work:

 # perf kvm stat report

    VM-EXIT    Samples  Samples%     Time%   Min Time   Max Time Avg time
