These values were only introduced during this release cycle, so it is

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.

If there are leds present in the OF tree, but the GPIOs for (some) of
them are unavailable, led_data doesn't get populated with correct
devices. Then, on device unbinding, one can crash the kernel.

Workaround this by setting led->gpio to invalid value early.

This is a clean up and doesn't change the behavior.

Bit fields should always be unsigned.  Otherwise pm_suspend_enabled will
be -1 when you want it to be 1.  The other bad thing is that the sparse
checker will complain 36 times if they aren't unsigned.

The other bitfields in that struct are unsigned already.

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 22242681 ("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.
