If dell_new_hk_type is true, dell_legacy_wmi_keymap will point to a memory
allocated in setup_new_hk_map().
In this case, the memory is not freed in current implementation.
This patch fixes the leak by kfree(dell_wmi_keymap) if dell_new_hk_type is true.

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER,
the caller must kfree the returned buffer if AE_OK is returned.
The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER,
and thus must check its return value before accessing
or kfree() on the buffer.
This patch adds return value checking for wmi_get_event_data()
and adds a missing kfree(obj) in the end of wmi_notify_debug

Stanse found that there are two NULL checks missing in ips_monitor. So
check their value too and bail out appropriately if the allocation
failed.
While at it, add one more kfree to the fail path. It is not necessary
now, but may be needed in the future when a new allocation is added.
And for completeness.
Also remove unneeded initialization of the variables. They are all set
right after their declaration.

Intel Core i3/5 platforms with integrated graphics support both CPU and
GPU turbo mode. CPU turbo mode is opportunistic: the CPU will use any
available power to increase core frequencies if thermal headroom is
available. The GPU side is more manual however; the graphics driver
must monitor GPU power and temperature and coordinate with a core
thermal driver to take advantage of available thermal and power headroom
in the package.
The intelligent power sharing (IPS) driver is intended to coordinate
this activity by monitoring MCP (multi-chip package) temperature and
power, allowing the CPU and/or GPU to increase their power consumption,
and thus performance, when possible. The goal is to maximize
performance within a given platform's TDP (thermal design point).

- Improve error handling, by explictly return zero for success, error otherwise
- WMI query command can have arbitrary input sized params
- WMI query command can have specific output sized params (0, 4, 128,..) byte
I like to go on here, but this is a rather intrusive change that should
be looked at first. I am sure the one or other thing can be done better or
there might be typo/bug somewhere.
This did not get any testing yet, only compile tested.
Next steps could be:
- Eventually introduce hp_wmi_perform_{read,write}_query macros
- Introduce new wireless query interface (0x1B)
- more

Depending on ACPI version (1.0 -> 32 bit) an integer could be
32 or 64 bit long. _WED internal concatenates two integers and
the return value will be 8 byte (2* 32 bit) or 16 byte (2* 64 bit)
long, depending on the ACPI version.
Also the data send with the WMI event is defined to be splitted into:
- Event ID -> 4 bytes
- Event Data -> 4 bytes
This gets messed up with new ACPI versions.
But it's a HP BIOS bug that may get fixed in the future
-> Support both, 16 and 8 byte _WED buffers.
Also the wrong assumption that from the event data sent, only the
first byte is relevant got cleaned up that it fits event_id/event_data
as described above.

It is now possible to assign options to AS and CC
on the command line - which is only used for built-in code.
{A,C}FLAGS_KERNEL was used both in the top-level Makefile
in the arch makefiles, thus users had no way to specify
additional options to AS, CC without overriding
the original value.
Introduce a new set of variables KBUILD_{A,C}FLAGS_KERNEL
that is used by arch specific files and free up
{A,C}FLAGS_KERNEL so they can be assigned on
the command line.
All arch Makefiles that used the old variables has been updated.

{A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile

additional options to AS, CC, LD when building modules
without overriding the original value.
Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE

Note: Previously we had a MODFLAGS variable for both
AS and CC. But in favour of consistency this was dropped.
So in some cases arch Makefile has one assignmnet replaced by
two assignmnets.
Note2: MODFLAGS was not documented and is dropped
without any notice. I do not expect much/any breakage
from this.

savedefconfig will save a minimal config to a file
named "defconfig".
The config symbols are saved in the same order as
they appear in the menu structure so it should
be possible to map them to the relevant menus
if desired.
The implementation was tested against several minimal
configs for arm which was created using brute-force.
There was one regression related to default numbers
which had their valid range further limited by another symbol.
Sample:
config FOO
int "foo"
default 4
config BAR
int "bar"
range 0 FOO
If FOO is set to 3 then BAR cannot take a value higher than 3.
But the current implementation will set BAR equal to 4.
This is seldomly used and the final configuration is OK,
and the fix was non-trivial.
So it was documented in the code and left as is.

Consider following kconfig file:
config TEST1
bool "test 1"
depends on TEST2
config TEST2
bool "test 2"
depends on TEST1
Previously kconfig would report:
foo:6:error: found recursive dependency: TEST2 -> TEST1 -> TEST2
With the following patch kconfig reports:
foo:5:error: recursive dependency detected!
foo:5: symbol TEST2 depends on TEST1
foo:1: symbol TEST1 depends on TEST2
Note that we now report where the offending symbols are defined.
This can be a great help for complex situations involving

Rename to a name that better match the other kconfig targets.
listnewconfig shall read as:

New options are now written to stdout so one can redirect the output.
Do not exit with an error code if there is new options.
These are feature changes compared to the original
nonint_oldconfig - but as this feature has not yet been in a

So drop the single letter options in favour of long options.
The long options are named equal to what we know from

Commit fc6055a5ba31e2c14e36e8939f9bf2b6d586a7f5 (net: Introduce
skb_orphan_try()) allows an early orphan of the skb and takes care on
tx timestamping, which needs the sk-reference in the skb on driver level.
So does the can-raw socket, which has not been taken into account here.
The patch below adds a 'prevent_sk_orphan' bit in the skb tx shared info,
which fixes the problem discovered by Matthias Fuchs here:
http://marc.info/?t=128030411900003&r=1&w=2
Even if it's not a primary tx timestamp topic it fits well into some skb
shared tx context. Or should be find a different place for the information to
protect the sk reference until it reaches the driver level?
