We are using the mips counters as the clock source, so we need to ensure
they are synced, else e.g. gettimeofday will return different values
depending on which core it was run.
Observed difference was about 8 seconds, causing ~8 seconds ping or time
running backwards for some programs.

This patch introduces common clock framework integration for all
configurable on-chip clocks on Alchemy chips:
- 2 or 3 PLLs which generate integer multiples of the root rate 12MHz,
- 6 dividers which take one of the 3 PLLs as input and divide their
rate by either multiples of 2 or 1 (Au1300).
- another bank of up to 6 muxes which take either one of the 6
above dividers or one of the PLLs directly and divide their rate
further by 1, 2, 3 or 4.
- a few other sources which are used by onchip peripherals and are
informational.
This implementation will take the clock tree as it was set up
by boot firmware: all in-kernel boards should continue to work
without having to set up the clock tree in board code.
CLK_IGNORE_DISABLED will be removed once all drivers have been
converted.

different if you call syscall() or the glibc wrapper. This patch
makes the kernel accept the calling convention when called by the
glibc wrapper.
The other two patches are trivial and remove unused headers, #includes
and adds the serial ports of the fastest C8000 workstation to the

On parisc we can not use the existing compat implementation for fanotify_mark()
because for the 64bit mask parameter the higher and lower 32bits are ordered
differently than what the compat function expects from big endian
architectures.
Specifically:
It finally turned out, that on hppa we end up with different assignments
of parameters to kernel arguments depending on if we call the glibc
wrapper function
int fanotify_mark (int __fanotify_fd, unsigned int __flags,
uint64_t __mask, int __dfd, const char *__pathname);
or directly calling the syscall manually
syscall(__NR_fanotify_mark, ...)
Reason is, that the syscall() function is implemented as C-function and
because we now have the sysno as first parameter in front of the other
parameters the compiler will unexpectedly add an empty paramenter in
front of the u64 value to ensure the correct calling alignment for 64bit
values.
This means, on hppa you can't simply use syscall() to call the kernel
fanotify_mark() function directly, but you have to use the glibc
function instead.
This patch fixes the kernel in the hppa-arch specifc coding to adjust
the parameters in a way as if userspace calls the glibc wrapper function
fanotify_mark().

Here are some small serial fixes that resolve some reported problems
that started in 3.15 with some serial drivers. And there's a new dt
binding for a serial driver, which was all that was needed for the
renesas serial driver.

Dell kernel driver dell-smo8800 provides same freefall interface as hp_accel so
program hpfall.c works also on Dell laptops. So rename it to freefall.c.
Dell driver does not provide hp::hddprotect led so make sure that freefall.c
works also if hp::hddprotect does not exist in sysfs.
Additionally write info to syslog.

Object-like macros are different than function-like macros:
https://gcc.gnu.org/onlinedocs/cpp/Object-like-Macros.htmlhttps://gcc.gnu.org/onlinedocs/cpp/Function-like-Macros.html
They are not parsed correctly, generating invalid intermediate
files (xmls) for cases like:
#define BIT_MASK (0xFF << BIT_SHIFT)
where "OxFF <<" is considered to be parameter type.
When parsing, we can differentiate beween these two types of macros by
checking whether there is at least one whitespace b/w "#define" and
first opening parenthesis.

The paragraph on mcelog currently describes kernel v2.6.31. In that
kernel the mce code (for i386, that is) was in transition. Ever since
v2.6.32 the situation is much simpler (eg, mcelog is now needed to
process events on almost all x86 machines, i386 and x86-64). Since this
"document is designed to provide a list of the minimum levels of
software necessary to run the 3.0 kernels" let's just describe that
situation.

If probe fails then we need to call pm_runtime_disable() to balance
out the previous pm_runtime_enable() call. Else it will cause
unbalanced pm_runtime_enable() call in the succeding probe call.
This anomaly was observed when the call to devm_phy_create() failed
with -EPROBE_DEFER.
Balance out the pm_runtime_enable() call in .remove() as well.

Prevent resources from being freed twice in case device_add() call
fails within phy_create(). Also use ida_simple_remove() instead of
ida_remove() as we had used ida_simple_get() to allocate the ida.

devm_ioremap_resource returns an ERR_PTR value, not NULL, on failure.
A simplified version of the semantic match that finds this problem is as
follows:
// <smpl>

expression e,e1;
statement S;
@@
*e = devm_ioremap_resource(...);
if (!e1) S
