Convert the struct i2c_msg initialization to C99 format. This makes
maintaining and editing the code simpler. Also helps once other fields
like transferred are added in future.

Without this patch /sys/class/rtc/$CONFIG_RTC_HCTOSYS_DEVICE/hctosys
contains a 1 (meaning "This rtc was used to initialize the system
clock") even if setting the time by do_settimeofday() at bootup failed.
The RTC can also be used to set the clock on resume, if it did 1,
otherwise 0. Previously there was no indication if the RTC was used
to set the clock in resume.
This uses only CONFIG_RTC_HCTOSYS_DEVICE for conditional compilation
instead of it and CONFIG_RTC_HCTOSYS to be more consistent.
rtc_hctosys_ret was moved to class.c so class.c no longer depends on
hctosys.c.

i.mx drivers should use clk_prepare_enable/clk_disable_unprepare() in
order to avoid clk warnings.
While at it, convert to devm_clk_get() since other devm_ functions are
used in this driver and it can also save some clk_put() calls.

clk_disable_unprepare()
clk_prepare_enable and clk_disable_unprepare combine clk_prepare and
clk_enable, and clk_disable and clk_unprepare. They make the code more
concise, and ensure that clk_unprepare is called when clk_enable fails.
A simplified version of the semantic patch that introduces calls to these
functions is as follows: (http://coccinelle.lip6.fr/)

There are several comparisons of a unsigned int to less than zero int
spear RTC driver. Such a check will always be true. In all these cases a
signed int is assigned to the unsigned variable, which is checked, before.
So the right fix is to make the checked variable signed as well. In one
case the check can be dropped completely, because all it does it returns
'err' if 'err' is less than zero, otherwise it returns 0. Since in this
particular case 'err' is always either 0 or less this is the same as just
returning 'err'.

The irq field of the jz4740_irc struct is unsigned. Yet we assign the
result of platform_get_irq() to it. platform_get_irq() may return a
negative error code and the code checks for this condition by checking if
'irq' is less than zero. But since 'irq' is unsigned this test will
always be false. Fix it by making 'irq' signed.

When calling rtc_device_unregister, we are not freeing the id used by the
driver. So when doing a unload/load cycle for a RTC driver (e.g. rmmod
rtc_cmos && modprobe rtc_cmos), its id is incremented by one. As a
consequence, we no longer have neither an rtc0 driver nor a
/proc/driver/rtc (as it only exists for the first driver).

To get time information via /proc/driver/rtc, only the first device (rtc0)
is used. If the rtcN (eg. rtc1 or rtc2) is used for the system clock,
there is no way to get information of rtcN via /proc/driver/rtc. With
this patch, the time data can be retrieved from the system clock RTC.
If the RTC_HCTOSYS_DEVICE is not defined, then rtc0 is used by default.

load_elf_interp() has interp_map_addr carefully described as
"uninitialized_var" and marked so as to avoid a warning. However if you
trace the code it is passed into load_elf_interp and then this value is
checked against NULL.
As this return value isn't used this is actually safe but it freaks
various analysis tools that see un-initialized memory addresses being read
before their value is ever defined.
Set it to NULL as a matter of programming good taste if nothing else

Xen's pciback points out a couple of deficiencies with vsscanf()'s
standard conformance:
- Trailing character matching cannot be checked by the caller: With a
format string of "(%x:%x.%x) %n" absence of the closing parenthesis
cannot be checked, as input of "(00:00.0)" doesn't cause the %n to be
evaluated (because of the code not skipping white space before the
trailing %n).
- The parameter corresponding to a trailing %n could get filled even if
there was a matching error: With a format string of "(%x:%x.%x)%n",
input of "(00:00.0]" would still fill the respective variable pointed to
(and hence again make the mismatch non-detectable by the caller).
This patch aims at fixing those, but leaves other non-conforming aspects
of it untouched, among them these possibly relevant ones:
- improper handling of the assignment suppression character '*' (blindly
discarding all succeeding non-white space from the format and input
strings),
- not honoring conversion specifiers for %n, - not recognizing the C99
conversion specifier 't' (recognized by vsprintf()).

The logic in do_raw_spin_lock() attempts to acquire a spinlock by invoking
arch_spin_trylock() in a loop with a delay between each attempt. Now
consider the following situation in a 2 CPU system:
1. CPU-0 continually acquires and releases a spinlock in a
tight loop; it stays in this loop until some condition X
is satisfied. X can only be satisfied by another CPU.
2. CPU-1 tries to acquire the same spinlock, in an attempt
to satisfy the aforementioned condition X. However, it
never sees the unlocked value of the lock because the
debug spinlock code uses trylock instead of just lock;
it checks at all the wrong moments - whenever CPU-0 has
locked the lock.
Now in the absence of debug spinlocks, the architecture specific spinlock
code can correctly allow CPU-1 to wait in a "queue" (e.g., ticket
spinlocks), ensuring that it acquires the lock at some point. However,
with the debug spinlock code, livelock can easily occur due to the use of
try_lock, which obviously cannot put the CPU in that "queue". This
queueing mechanism is implemented in both x86 and ARM spinlock code.
Note that the situation mentioned above is not hypothetical. A real
problem was encountered where CPU-0 was running hrtimer_cancel with
interrupts disabled, and CPU-1 was attempting to run the hrtimer that
CPU-0 was trying to cancel.
Address this by actually attempting arch_spin_lock once it is suspected
that there is a spinlock lockup. If we're in a situation that is
described above, the arch_spin_lock should succeed; otherwise other
timeout mechanisms (e.g., watchdog) should alert the system of a lockup.
Therefore, if there is a genuine system problem and the spinlock can't be
acquired, the end result (irrespective of this change being present) is
the same. If there is a livelock caused by the debug code, this change
will allow the lock to be acquired, depending on the implementation of the
lower level arch specific spinlock code.

Premit use of another algorithm than the default first-fit one. For
example a custom algorithm could be used to manage alignment requirements.
As I can't predict all the possible requirements/needs for all allocation
uses cases, I add a "free" field 'void *data' to pass any needed
information to the allocation function. For example 'data' could be used
to handle a structure where you store the alignment, the expected memory
bank, the requester device, or any information that could influence the
allocation algorithm.
An usage example may look like this:
struct my_pool_constraints {
int align;
int bank;
...
};
unsigned long my_custom_algo(unsigned long *map, unsigned long size,
unsigned long start, unsigned int nr, void *data)
{
struct my_pool_constraints *constraints = data;
...
deal with allocation contraints
...
return the index in bitmap where perform the allocation
}
void create_my_pool()
{
struct my_pool_constraints c;
struct gen_pool *pool = gen_pool_create(...);
gen_pool_add(pool, ...);
gen_pool_set_algo(pool, my_custom_algo, &c);
}
Add of best-fit algorithm function:
most of the time best-fit is slower then first-fit but memory fragmentation
is lower. The random buffer allocation/free tests don't show any arithmetic
relation between the allocation time and fragmentation but the
best-fit algorithm
is sometime able to perform the allocation when the first-fit can't.
This new algorithm help to remove static allocations on ESRAM, a small but
fast on-chip RAM of few KB, used for high-performance uses cases like DMA
linked lists, graphic accelerators, encoders/decoders. On the Ux500
(in the ARM tree) we have define 5 ESRAM banks of 128 KB each and use of
static allocations becomes unmaintainable:
cd arch/arm/mach-ux500 && grep -r ESRAM .
./include/mach/db8500-regs.h:/* Base address and bank offsets for ESRAM */
./include/mach/db8500-regs.h:#define U8500_ESRAM_BASE 0x40000000

I want to use genalloc to do dynamic allocations but I need to be able to

The result of converting an integer value to another signed integer type
that's unable to represent the original value is implementation defined.
(See notes in section 6.3.1.3 of the C standard.)
In match_number(), the result of simple_strtol() (which returns type long)
is assigned to a value of type int.
Instead, handle the result of simple_strtol() in a well-defined way, and
return -ERANGE if the result won't fit in the int variable used to hold
the parsed result.
No current callers pay attention to the particular error value returned,
so this additional return code shouldn't do any harm.
