Use the same fallback to normal IO in case of write

fsx file -d -Z -r 4096 -w 4096
Report:
129(129 mod 256): TRUNCATE DOWN from 0x3ff01 to 0xb3f6
130(130 mod 256): WRITE 0x22000 thru 0x2dfff (0xc000 bytes) HOLE
Thanks to Jan for helping me on this problem.
The ideal solution suggested by Jan Kara would be to use
cont_write_begin() but affs direct_IO shouldn't be used a lot anyway...

The spinlock in eventfd_poll is trying to protect the count of events so
it can decide if it should return POLLIN, POLLERR, or POLLOUT. But,
because of the way we drop the lock after calling poll_wait, and drop it
again before returning, we have the same pile of races with the lock as
we do with a single read of ctx->count().
This replaces the lock with a read barrier and single read.
eventfd_write does a single bump of ctx->count, so this should not add
new races with adding events. eventfd_read is similar, it will do a
single decrement with the lock held, and so we're making the race with
concurrent readers slightly larger.
This spinlock is the top CPU user in kernel code during one of our
workloads. Removing it gives us a ~2% boost.

When updating PT_NOTE header size (ie. p_memsz), an overflow issue
happens with the following bogus note entry:
n_namesz = 0xFFFFFFFF
n_descsz = 0x0
n_type = 0x0
This kind of note entry should be dropped during updating p_memsz. But
because n_namesz is 32bit, after (n_namesz + 3) & (~3), it's overflow to
0x0, the note entry size looks sane and reserved.
When userspace (eg. crash utility) is trying to access such bogus note,
it could lead to an unexpected behavior (eg. crash utility segment fault
because it's reading bogus address).
The source of bogus note hasn't been identified yet. At least we could
drop the bogus note so user space wouldn't be surprised.

Define new kexec preprocessor macros IND_*_BIT that define the bit
position of the kimage entry flags. Change the existing IND_* flag macros
to be defined as bit shifts of the corresponding IND_*_BIT macros. Also
wrap all C language code in kexec.h with #if !defined(__ASSEMBLY__) so
assembly files can include kexec.h to get the IND_* and IND_*_BIT macros.
Some CPU instruction sets have tests for bit position which are convenient
in implementing routines that operate on the kimage entry list. The
addition of these bit position macros in a common location will avoid
duplicate definitions and the chance that changes to the IND_* flags will
not be propagated to assembly files.

Simplify the code around one of the conditionals in the kexec_load syscall
routine.
The original code was confusing with a redundant check on KEXEC_ON_CRASH
and comments outside of the conditional block. This change switches the
order of the conditional check, and cleans up the comments for the
conditional. There is no functional change to the code.

Paul said:
: The kexec_load declaration isn't very useful for userspace, see the patch

: In that last discussion no one has been able to point to an actual user of

struct kimage has a member destination which is used to store the real
destination address of each page when load segment from user space buffer
to kernel. But we never retrieve the value stored in kimage->destination,
so this member variable in kimage and its assignment operation are
redundent code.
I guess for_each_kimage_entry just does the work that kimage->destination
is expected to do.
So in this patch just make a cleanup to remove it.

Pull suspend-to-idle updates from Rafael Wysocki:
"Suspend-to-idle timer quiescing support for v3.20-rc1
Until now suspend-to-idle has not been able to save much more energy
than runtime PM because of timer interrupts that periodically bring
CPUs out of idle while they are waiting for a wakeup interrupt. Of
course, the timer interrupts are not wakeup ones, so the handling of
them can be deferred until a real wakeup interrupt happens, but at the
same time we don't want to mass-expire timers at that point.
The solution is to suspend the entire timekeeping when the last CPU is
entering an idle state and resume it when the first CPU goes out of
idle. That has to be done with care, though, so as to avoid accessing
suspended clocksources etc. end we need extra support from idle
drivers for that.
This series of commits adds support for quiescing timers during
suspend-to-idle and adds the requisite callbacks to intel_idle and the
ACPI cpuidle driver"

The dw_wdt_set_top() function takes in a value in seconds. In
dw_wdt_open() we were calling it with a value that's supposed to
represent the maximum value programmed into the "top" register with a
comment saying that we were trying to set the watchdog to its maximum
value. Instead we ended up setting the watchdog to ~15 seconds.
Let's fix this. However, setting things to the "max" gives me an 86
second watchdog in the system I'm looking at. 86 seconds feels a
little too long. We'll explicitly choose 30 seconds as a more
reasonable value.
NOTE: Ideally this driver should be transitioned to be a real watchdog
driver. Then we could use "watchdog_init_timeout" and let the timeout
be specified in a number of ways (device tree, module parameter, etc).
This patch should be considered a bit of a stopgap solution.

On some dw_wdt implementations the "top" register may be initted to 0
at bootup. In such a case, each "pat" of the watchdog will reset the
timer to 0xffff. That's pretty short.
The input clock of the wdt can be any of a wide range of values. On
an rk3288 system, I've seen the wdt clock be 24.75 MHz. That means
each tick is ~40ns and we'll count to 0xffff in ~2.6ms.
Because of the above two facts, it's a really good idea to pat the
watchdog after initting the "top" register properly and before
enabling the watchdog. If you don't then there's no way we'll get the
next heartbeat in time.
Jisheng Zhang fixed this problem on some dw_wdt versions by using the
TOP_INIT feature. However, the dw_wdt on rk3288 doesn't have TOP_INIT
so it's a good idea to also pat the watchdog manually.
