Add a new sysfs_streq() string comparison function, which ignores
the trailing newlines found in sysfs inputs. By example:
sysfs_streq("a", "b") ==> false
sysfs_streq("a", "a") ==> true
sysfs_streq("a", "a\n") ==> true
sysfs_streq("a\n", "a") ==> true
This is intended to simplify parsing of sysfs inputs, letting them
avoid the need to manually strip off newlines from inputs.

Remove the leap second handling from second_overflow(), which doesn't have to
check for it every second anymore. With CONFIG_NO_HZ this also makes sure the
leap second is handled close to the full second. Additionally this makes it
possible to abort a leap second properly by resetting the STA_INS/STA_DEL
status bits.

As TICK_LENGTH_SHIFT is used for more than just the tick length, the name

time_offset is already a 64bit value but its resolution barely used, so this
makes better use of it by replacing SHIFT_UPDATE with TICK_LENGTH_SHIFT.
Side note: the SHIFT_HZ in SHIFT_UPDATE was incorrect for CONFIG_NO_HZ and the
primary reason for changing time_offset to 64bit to avoid the overflow.

This changes time_freq to a 64bit value and makes it static (the only outside
user had no real need to modify it). Intermediate values were already 64bit,
so the change isn't that big, but it saves a little in shifts by replacing
SHIFT_NSEC with TICK_LENGTH_SHIFT. PPM_SCALE is then used to convert between
user space and kernel space representation.

This adds a few more things from the ntp nanokernel related to user space.
It's now possible to select the resolution used of some values via STA_NANO
and the kernel reports in which mode it works (pll/fll).
If some values for adjtimex() are outside the acceptable range, they are now
simply normalized instead of letting the syscall fail. I removed
MOD_CLKA/MOD_CLKB as the mapping didn't really makes any sense, the kernel
doesn't support setting the clock.

x86 is the only arch right now, which provides an optimized for
div_long_long_rem and it has the downside that one has to be very careful that
the divide doesn't overflow.
The API is a little akward, as the arguments for the unsigned divide are
signed. The signed version also doesn't handle a negative divisor and
produces worse code on 64bit archs.
There is little incentive to keep this API alive, so this converts the few
users to the new API.

Rename div64_64 to div64_u64 to make it consistent with the other divide
functions, so it clearly includes the type of the divide. Move its definition
to math64.h as currently no architecture overrides the generic implementation.
They can still override it of course, but the duplicated declarations are
avoided.

The current do_div doesn't explicitly say that it's unsigned and the signed
counterpart is missing, which is e.g. needed when dealing with time values.
This introduces 64bit signed/unsigned divide functions which also attempts to
cleanup the somewhat awkward calling API, which often requires the use of
temporary variables for the dividend. To avoid the need for temporary
variables everywhere for the remainder, each divide variant also provides a
version which doesn't return the remainder.
Each architecture can now provide optimized versions of these function,
otherwise generic fallback implementations will be used.
As an example I provided an alternative for the current x86 divide, which
avoids the asm casts and using an union allows gcc to generate better code.
It also avoids the upper divde in a few more cases, where the result is known
(i.e. upper quotient is zero).

Since recent smpboot 32/64-bit merge, my dual Xeon with HT has been
booting only 2 of its 4 cpus (when running an i386 kernel; but x86_64
is okay). J.A. Magallón reports the same.
native_cpu_up: bad cpu 2
native_cpu_up: bad cpu 3
The mach-default cpu_present_to_apicid() was just returning cpu number
(2, 3) instead of apicid (6, 7): looks like we now need the x86_64 code
even for the i386 case.
Comparing with other versions of cpu_present_to_apicid(), it seems a
good idea to include an NR_CPUS test too, since cpu_present() doesn't
include that; but that wasn't a problem here, and may no problem at all.
Prior to that smpboot merge, my Xeon booted the two HT siblings on one
physical first, then the two siblings on the other physical after - when
i386, but alternated them when x86_64. Since the merge, the x86_64
sequence is unchanged, but the i386 sequence is now like x86_64.
I prefer this consistency, and I prefer the new sequence: booting with
maxcpus=2 then uses the independent physicals without HT sharing.

the 'reboot_force' flag is a notion that non-PC subarchitectures do
not have.
also, unify the X86_BIOS_REBOOT option between 32-bit and 64-bit

that way.

This adds a pnp_get_resource() that works the same way as
platform_get_resource(). This will enable us to consolidate
many pnp_resource_table references in one place, which will
make it easier to make the table dynamic.

Rene Herman <rene.herman@gmail.com> recently removed the only in-tree
driver uses of:
pnp_init_resource_table()
pnp_manual_config_dev()
pnp_resource_change()
in this change:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=109c53f840e551d6e99ecfd8b0131a968332c89f
These are no longer used in the PNP core either, so we can just remove
them completely.
It's possible that there are out-of-tree drivers that use these
interfaces. They should be changed to either (1) use PNP quirks
to work around broken hardware or firmware, or (2) use the sysfs
interfaces to control resource usage from userspace.

Add pnp_init_resources(struct pnp_dev *) to replace
pnp_init_resource_table(), which takes a pointer to the
pnp_resource_table itself. Passing only the pnp_dev * reduces
the possibility for error in the caller and removes the
pnp_resource_table implementation detail from the interface.
Even though pnp_init_resource_table() is exported, I did not
export pnp_init_resources() because it is used only by the PNP
core.

When we call protocol->get() and protocol->set() methods, we currently
supply pointers to both the pnp_dev and the pnp_resource_table even
though the pnp_resource_table should always be the one associated with
the pnp_dev.
This removes the pnp_resource_table arguments to make it clear that
these methods only operate on the specified pnp_dev.
