%pF and %pf are functionally equivalent to %pS and %ps conversion
specifiers. The former are deprecated, therefore switch the current users
to use the preferred variant.
The changes have been produced by the following command:
git grep -l '%p[fF]' | grep -v '^\(tools\|Documentation\)/' | \
while read i; do perl -i -pe 's/%pf/%ps/g; s/%pF/%pS/g;' $i; done
And verifying the result.

<linux/sched/clock.h>
We are going to split <linux/sched/clock.h> out of <linux/sched.h>, which
will have to be picked up from other headers and .c files.
Create a trivial placeholder <linux/sched/clock.h> file that just
maps to <linux/sched.h> to make this patch obviously correct and
bisectable.
Include the new header in the files that are going to need it.

The length argument to strlcpy was still wrong. It could overflow the end of
full_boot_str by 5 bytes. Instead of strcat and strlcpy, just use snprint.

Commit 117a0c5fc9c2d06045bd217385b2b39ea426b5a6 ("sparc: kernel: using
strlcpy() instead of strcpy()") added a bug to ldom_reboot in
arch/sparc/kernel/ds.c
- strcpy(full_boot_str + strlen("boot "), boot_command);
+ strlcpy(full_boot_str + strlen("boot "), boot_command,
+ sizeof(full_boot_str + strlen("boot ")));
That last sizeof() expression evaluates to sizeof(size_t) which is
not what was intended.
Also even the corrected:
sizeof(full_boot_str) + strlen("boot ")
is not right as the destination buffer length is just plain
"sizeof(full_boot_str)" and that's what the final argument
should be.

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications. For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out. Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.
Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
are flagged as __cpuinit -- so if we remove the __cpuinit from
arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
content into no-ops as early as possible, since that will get rid
of these warnings. In any case, they are temporary and harmless.
This removes all the arch/sparc uses of the __cpuinit macros from
C files and removes __CPUINIT from assembly files. Note that even
though arch/sparc/kernel/trampoline_64.S has instances of ".previous"
in it, they are all paired off against explicit ".section" directives,
and not implicitly paired with __CPUINIT (unlike mips and arm were).

For the related next strcpy(), the destination length is less than 512,
but the source maximize length may be 'OPROMMAXPARAM' (4096) which is
more than 512.
One work flow may:
openprom_sunos_ioctl() -> if (cmd == OPROMSETOPT)
getstrings() -> will alloc buffer with size 'OPROMMAXPARAM'.
opromsetopt() -> devide the buffer into 'var' and 'value'
of_set_property() -> pass
prom_setprop() -> pass
ldom_set_var()
And do not mind the additional 4 alignment buffer increasing, since
'sizeof(pkt) - sizeof(pkt.header)' is 4 alignment at least.

'boot_command_line' and 'full_boot_str' has a fix length, 'cmdline_p' and
'boot_command' maybe larger than them. So use strlcpy() instead of strcpy()
to avoid memory overflow.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

The DS driver registers as a subsys_initcall() but this can be too
early, in particular this risks registering before we've had a chance
to allocate and setup module_kset in kernel/params.c which is
performed also as a subsyts_initcall().
Register DS using device_initcall() insteal.

This makes vio_register_driver() get the module owner & name at compile
time like PCI drivers do, and adds a name pointer directly in struct
vio_driver to avoid having to explicitly initialize the embedded

Adapt new API. Almost change is trivial, most important change are to
remove following like =operator.
cpumask_t cpu_mask = *mm_cpumask(mm);
cpus_allowed = current->cpus_allowed;
Because cpumask_var_t is =operator unsafe. These usage might prevent
kernel core improvement.
No functional change.

Fix all of the problems spotted by CONFIG_DEBUG_SECTION_MISMATCH under
arch/sparc during a 64-bit defconfig build.
They fall into two categorites:
1) of_device_id is marked as __initdata, and we can never do this
since these objects sit in the device core data structures way
past boot. So even if a driver will never be reloaded, we have
to keep the device ID table around.
Mark such cases const instead.
2) The bootmem alloc/free handling code in mdesc.c was not fully
marked __init as it should be, thus generating a reference
to free_bootmem_late() (which is __init) from non-__init code.

sparc64
Impact: cleanup, futureproof
In fact, all cpumask ops will only be valid (in general) for bit
numbers < nr_cpu_ids. So use that instead of NR_CPUS in various
places.
This is always safe: no cpu number can be >= nr_cpu_ids, and
nr_cpu_ids is initialized to NR_CPUS at boot.

People keep on doing

testing it only on x86_64 and this generates a warning storm on
powerpc, sparc64, etc. Because they use `long', not `long long'.
Quite a few 64-bit architectures are using `long' for their
s64/u64 types. We should convert them all to `long long'.
Update types.h so we use unsigned long long for u64 and
fix all warnings in sparc64 code.
Tested with an allnoconfig, defconfig and allmodconfig builds.
This patch introduces additional warnings in several drivers.
These will be dealt with in separate patches.

o Move all files from sparc64/kernel/ to sparc/kernel
- rename as appropriate
o Update sparc/Makefile to the changes
o Update sparc/kernel/Makefile to include the sparc64 files
NOTE: This commit changes link order on sparc64!
Link order had to change for either of sparc32 and sparc64.
And assuming sparc64 see more testing than sparc32 change link
order on sparc64 where issues will be caught faster.
