These values were only introduced during this release cycle, so it is
still early enough to get them right.
alpha uses the same values that are in asm-generic/fcntl.h, so just
remove them.
parisc uses the values interchanged for no apparent reason, so remove
them to give us consistency across all architectures.

Now that all host programs use static for all private functions and
forward prototypes for all extern functions, add -Wmissing-prototypes to
HOSTCFLAGS in the hopes of keeping it that way.
All versions of GCC supported by the kernel handle -Wmissing-prototypes.

Commit 8177e6d6dfb9cd03d9bdeb647c32161f8f58f686 ("nfsd: clean up
readdirplus encoding") introduced single character typo in nfs3 readdir+
implementation. Unfortunately that typo has quite bad side effects:
random memory corruption, followed (on my box) with immediate
spontaneous box reboot.
Using 'p1' instead of 'p' fixes my Linux box rebooting whenever VMware
ESXi box tries to list contents of my home directory.

1. At the end of smtc_distribute_timer, nextstamp is valid and has already
passed so we goto repeat.
2. Nothing updates nextstamp (only updated if the timeout is in the future
And we just decided it is in the past)
3. At the end nextstamp still has the same value so it is still valid and
in the past.
4. This repeats until read_c0_count has a value which causes nextstamp to
be in the future.

Since commit 22242681cff52bfb7cba5d2a37b91802be7a4e4c ("MIPS: Extend
COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this
size will cause an build failure with default CONFIG_FRAME_WARN settings.
Although current users of such array variables are all early bootstrap
code and not likely to cause real stack overflow (thread_info corruption),
it is preferable to to declare these arrays static with __initdata.

Running a 64-bit kernel on a 64-bit CPU without an FPU would cause the
emulator to run in 32-bit mode. The c0_Status.FR bit is wired to zero
on systems without an FPU, so using that bit to decide how the emulator
behaves doesn't allow for proper emulation on 64-bit FPU-less
processors.
Instead, we need to select the emulator mode based on the user-space
ABI. Since the thread flag TIF_32BIT_REGS is used to set c0_Status.FR,
we can just use it to decide if the emulator should be in 32-bit or
64-bit mode.

On s390 there are two ways of specifying the system call number for
the svc instruction. The standard way is to use the immediate field
in the instruction (or to use EXecute for values unknown during
assemble time). This can encode 256 system calls.
The kernel ABI also allows to put the system call number in r1 and
then execute svc 0 to enable system call numbers > 255.
It turns out that single stepping svc 0 is broken, since the PER
program check handler uses r1. We have to use a different register.

In a system where the ctrl-alt-del init action initiated by signal
quiesce suspends the machine the quiesce handler override for
_machine_restart, _machine_halt and _machine_power_off needs to be
undone, otherwise the override is still present in the resumed
system. The next shutdown would then load the quiesce state psw
instead of performing the correct shutdown action.

After an IPL from NSS the uptime of the system is incorrect. The reason
is that the startup code in head.S is not executed in case of an IPL
from NSS. Due to that sched_clock_base_cc which is used to initialze
wall_to_monotonic contains the time stamp when the NSS has been created
instead of the time stamp of the system start.
Reinitialize the cputime accounting values in create_kernel_nss after
the SAVESYS CP command that created the NSS segment.

degraded.
Normally is it not safe to allow a raid5 that is both dirty and
degraded to be assembled without explicit request from that admin, as
it can cause hidden data corruption.
This is because 'dirty' means that the parity cannot be trusted, and
'degraded' means that the parity needs to be used.
However, if the device that is missing contains only parity, then
there is no issue and assembly can continue.
This particularly applies when a RAID5 is being converted to a RAID6
and there is an unclean shutdown while the conversion is happening.
So check for whether the degraded space only contains parity, and
in that case, allow the assembly.

When a reshape finds that it can add spare devices into the array,
those devices might already be 'in_sync' if they are beyond the old
size of the array, or they might not if they are within the array.
The first case happens when we change an N-drive RAID5 to an
N+1-drive RAID5.
The second happens when we convert an N-drive RAID5 to an
N+1-drive RAID6.
So set the flag more carefully.
Also, ->recovery_offset is only meaningful when the flag is clear,
so only set it in that case.
This change needs the preceding two to ensure that the non-in_sync
device doesn't get evicted from the array when it is stopped, in the
case where v0.90 metadata is used.

This is a combination that didn't really make sense before.
However when a reshape is converting e.g. raid5 -> raid6, the extra
device is not fully in-sync, but is certainly active and contains
important data.
So allow that start to be meaningful and in particular get
the 'recovery_offset' value (which is needed for any non-in-sync
active device) from the reshape_position.

pcpu_extend_area_map() had the following two bugs.
* It should return 1 if pcpu_lock was dropped and reacquired but it
returned 0. This could lead to oops if free_percpu() races with
area map extension.
* pcpu_mem_free() was called under pcpu_lock. pcpu_mem_free() might
end up calling vfree() which isn't IRQ safe. This could lead to
deadlock through lock order inversion via IRQ.
In addition, Linus pointed out that the temporary lock dropping and
subtle three-way return value of pcpu_extend_area_map() was very ugly
and suggested to split the function into two - pcpu_need_to_extend()
and pcpu_extend_area_map().
This patch restructures pcpu_extend_area_map() as suggested and fixes
the two bugs.

PPS events must be recorded according to PPS's mode settings.
If a process asks for (i.e.) capture-assert events only, when the PPS
client calls the pps_event() function to save the current PPS event, we
should verify the event type and then discard unwanted ones.
Also, without this patch userland processes waiting for a specific PPS
event (assert or clear but not both) may be awakened at wrong time.

The current code checks for non-NULL though which causes kernel oops in

v3020_mmio_read_bit() always returns 0 when left_shift > 7.
v3020_mmio_read_bit()'s return type is (unsigned char). The code returns
a value masked by (1 << left_shift) that is casted to the return type. If
left_shift is larger than 7, the cast will always result in a 0 return
value. The problem was discovered with left_shift = 16, and the included
patch corrects the problem.
The bug was introduced in the last (Apr 3 2009) commit of the file, kernel
versions 2.6.30 and later.
