Clemens points out that we need to use compat_ptr() in order to safely
cast from u64 to addresses of a 32-bit usermode client.
Before, our conversion went wrong
- in practice if the client cast from pointer to integer such that
sign-extension happened, (libraw1394 and libdc1394 at least were not
doing that, IOW were not affected)
or
- in theory on s390 (which doesn't have FireWire though) and on the
tile architecture, regardless of what the client does.
The bug would usually be observed as the initial get_info ioctl failing
with "Bad address" (EFAULT).

With gcc4.6, some instances of concrete inlined function looks redundant
and broken, because it appears inside of a concrete instance and its
call_file and call_line are same as the original abstruct's decl_file
and decl_line respectively.
e.g.
[ d1aa] subprogram
external (flag) Yes
name (strp) "add_timer"
decl_file (data1) 2 ;here is original
decl_line (data2) 847 ;line and file
prototyped (flag) Yes
inline (data1) inlined (1)
sibling (ref4) [ d1c6]
...
[ 11d84] subprogram
abstract_origin (ref4) [ d1aa] ; concrete instance
low_pc (addr) .text+0x000000000000246f <add_timer>
high_pc (addr) .text+0x000000000000248b <mod_timer_pending>
frame_base (block1) [ 0] call_frame_cfa
sibling (ref4) [ 11dd9]
[ 11d9f] formal_parameter
abstract_origin (ref4) [ d1b9]
location (data4) location list [ 701b]
[ 11da8] inlined_subroutine
abstract_origin (ref4) [ d1aa] ; redundant instance
low_pc (addr) .text+0x000000000000247e <add_timer+0xf>
high_pc (addr) .text+0x0000000000002480 <add_timer+0x11>
call_file (data1) 2 ; call line and file
call_line (data2) 847 ; are same as above
Those redundant instances leads unwilling results;
e.g. find probe points inside of functions even if we specify
a function entry as below;
$ perf probe -V add_timer
Available variables at add_timer
@<add_timer+0>
struct timer_list* timer
@<add_timer+15>
(No matched variables)
So, this filters out those redundant instances based on call-site and
decl-site information.

gcc 4.6 generates a concrete out-of-line instance when there is a
function which is implicitly inlined somewhere but also has its own
instance. The concrete out-of-line instance means that it has an
abstract origin of the function which is referred by not only
inlined-subroutines but also a concrete subprogram.
Since current dwarf_func_inline_instances() can find only instances of
inlined-subroutines, this introduces new die_walk_instances() to find
both of subprogram and inlined-subroutines.
e.g. without this,
Available variables at sched_group_rt_period
@<cpu_rt_period_read_uint+9>
struct task_group* tg
perf probe failed to find actual subprogram instance of
sched_group_rt_period().
With this,
Available variables at sched_group_rt_period
@<cpu_rt_period_read_uint+9>
struct task_group* tg
@<sched_group_rt_period+0>
struct task_group* tg
Now it found the sched_group_rt_period() itself.

Fix variable searching logic to search one in inner than local scope or
global(CU) scope. In the other words, skip searching in intermediate
scopes.
e.g., in the following code,
int var1;
void inline infunc(int i)
{
i++; <--- [A]
}
void func(void)
{
int var1, var2;
infunc(var2);
}
At [A], "var1" should point the global variable "var1", however, if user
mis-typed as "var2", variable search should be failed. However, current
logic searches variable infunc() scope, global scope, and then func()
scope. Thus, it can find "var2" variable in func() scope. This may not
be what user expects.
So, it would better not search outer scopes except outermost (compile
unit) scope which contains only global variables, when it failed to find
given variable in local scope.
E.g.
Without this:
$ perf probe -V pre_schedule --externs > without.vars
With this:
$ perf probe -V pre_schedule --externs > with.vars
Check the diff:
$ diff without.vars with.vars
88d87
< int cpu
133d131
< long unsigned int* switch_count
These vars are actually in the scope of schedule(), the caller of
pre_schedule().

Fix perf probe to search local variables in appropriate local inlined
function scope. For example, pre_schedule() has only 2 local variables,
as below;
$ perf probe -L pre_schedule
<pre_schedule@/home/mhiramat/ksrc/linux-2.6/kernel/sched.c:0>
0 static inline void pre_schedule(struct rq *rq, struct task_struct *prev)
{
2 if (prev->sched_class->pre_schedule)
3 prev->sched_class->pre_schedule(rq, prev);
}
However, current perf probe shows 4 local variables on pre_schedule(),
because it searches variables in the caller(schedule()) scope.
$ perf probe -V pre_schedule
Available variables at pre_schedule
@<schedule+445>
int cpu
long unsigned int* switch_count
struct rq* rq
struct task_struct* prev
This patch fixes this issue by searching variables in the local scope of
the instance of inlined function. Here is the result.
$ perf probe -V pre_schedule
Available variables at pre_schedule
@<schedule+445>
struct rq* rq
struct task_struct* prev

Fix line-range collector to walk all instances of inlined function,
because some execution paths can be optimized out depending on the
function argument of instances.
E.g.)
inline_func (arg) {
if (arg)
do_something;
else
do_another;
}
func_A() {
inline_func(1)
}
func_B() {
inline_func(0)
}
In this case, func_A may have only do_something code and func_B may have
only do_another.

Fix perf probe to walk through the lines of all nested inlined function
call sites and declared lines when a whole CU is passed to the line
walker.
The die_walk_lines() can have two different type of DIEs, subprogram (or
inlined-subroutine) DIE and CU DIE.
If a caller passes a subprogram DIE, this means that the walker walk on
lines of given subprogram. In this case, it just needs to search on
direct children of DIE tree for finding call-site information of inlined
function which directly called from given subprogram.
On the other hand, if a caller passes a CU DIE to the walker, this means
that the walker have to walk on all lines in the source files included
in given CU DIE. In this case, it has to search whole DIE trees of all
subprograms to find the call-site information of all nested inlined
functions.
Without this patch:
$ perf probe --line kernel/cpu.c:151-157
</home/mhiramat/ksrc/linux-2.6/kernel/cpu.c:151>
static int cpu_notify(unsigned long val, void *v)
{
154 return __cpu_notify(val, v, -1, NULL);
}
With this:
$ perf probe --line kernel/cpu.c:151-157
</home/mhiramat/ksrc/linux-2.6/kernel/cpu.c:151>
152 static int cpu_notify(unsigned long val, void *v)
{
154 return __cpu_notify(val, v, -1, NULL);
}
As you can see, --line option with source line range shows the declared
lines as probe-able.

Fix line walker to check whether a given DIE is CU or not.

DIEs.

Debuginfo analysis failed. (-2)
Error: Failed to show lines. (-2)
This fixes that bug, as below.

At least some Apples program the GPU into a state that wedges the engine
once userspace starts trying to perform accelerated operations. Executing
the Atom init scripts gets the hardware back into a working state. The
same hardware works fine when booted via BIOS emulation, so let's just
execute the init scripts on Apples when we're using EFI.

We have two sources of information about panel capabilities on mobile
radeon - the BIOS, which gives us a native mode, and the panel's preferred
mode. In theory these two will always match, but there's some corner cases
where the BIOS hasn't been fully initialised and so the native mode in it
ends up with default values. However, if we get a panel with reasonable
EDID, it's probably the case that the panel's preferred mode does actually
represent the panel capabilities. This patch handles that case by replacing
the native mode with the panel's preferred mode if the resolutions don't
match. Systems without a valid internal panel EDID will still use the BIOS
native mode.

This works well for usb_del_gadget_udc() but device_unregister() can't
deal with it. Therefore we rely on the fact the we always have a parent
device and only then remove the device.

an 'unhandled fault' is causes when a gadget driver calls
usb_gadget_connect() while the USB cable isn't plugged into
the OTG port.
the fault is caused by an access to MUSB's memory space
while its clock is turned off due to pm_runtime kicking
in.
in order to fix the fault, we enclose musb_gadget_pullup()
with pm_runtime_get_sync() ... pm_runtime_put() calls to
be sure we will always reach that path with clock turned on.

- USB_GADGET_MUSB_HDRC is no longer selectable because it
depends on the removed USB_MUSB_PERIPHERAL and USB_MUSB_OTG
options
- The Kconfig comment still says "Enable Host or Gadget support
to see Inventra options", even though you now need to enable
both of them to see Inventra options.
Fix the dependency and drop the anyway unnecessary comment.

For bMaxPacketSize0 we usually take what is specified in ep0->maxpacket.
This is fine in most cases, however on SuperSpeed bMaxPacketSize0
specifies the exponent instead of the actual size in bytes. The only
valid value on SS is 9 which denotes 512 bytes.

The code in this block is unused and the Author is fine with removing:
| These functions were used to debug unstable hw fifo while developing
| fusb300. It's much more stable now.
| So these functions can be removed.

CONFIG_REGMAP_I2C/SPI are set to m when selected by a tristate config
option that's set to m. The regmap modules don't specify a license, so
fail to link to regmap_init at load time, since that is EXPORT_SYMBOL_GPL.
Fix this by specifying a license for the regmap modules.

Just like files-layout, blocks & objects layouts are part of the
NFS 4.1 protocol and should be automatically selected if NFS_4_1
is selected. The small problem is that these depend on other
Kernel support being present, while files only depends on NFS
itself.
This patch removes from the user choice the presence of objects
and blocks layout. But makes sure these are selected only if
the depended subsystems are present in the Kernel.

I2S in Exynos4 and S5PC110(S5PV210) has a internal dma.
It can be used low power audio mode and 2nd channel transfer.
This patch can support idma.

Commit df5e6223407e ("ext4: fix deadlock in ext4_symlink() in ENOSPC
conditions") recalculated the number of credits needed for a long
symlink, in the process of splitting it into two transactions. However,
the first credit calculation under-counted because if selinux is
enabled, credits are needed to create the selinux xattr as well.
Overrunning the reservation will result in an OOPS in
jbd2_journal_dirty_metadata() due to this assert:
J_ASSERT_JH(jh, handle->h_buffer_credits > 0);
Fix this by increasing the reservation size.

In rt2800usb_work_txdone we check flags in order:
- ENTRY_OWNER_DEVICE_DATA
- ENTRY_DATA_STATUS_PENDING
- ENTRY_DATA_IO_FAILED
Modify flags in separate order in rt2x00usb_interrupt_txdone, to avoid
processing entries in _txdone with wrong flags or skip processing
ready entries.
