[PATCH] Fix RLIMIT_RTPRIO breakage

RLIMIT_RTPRIO is supposed to grant non privileged users the right to use
SCHED_FIFO/SCHED_RR scheduling policies with priorites bounded by the
RLIMIT_RTPRIO value via sched_setscheduler(). This is usually used by
audio users.

Unfortunately this is broken in 2.6.13rc3 as you can see in the excerpt
from sched_setscheduler below:

        /*
         * Allow unprivileged RT tasks to decrease priority:
         */
        if (!capable(CAP_SYS_NICE)) {
                /* can't change policy */
                if (policy != p->policy)
                        return -EPERM;

After the above unconditional test which causes sched_setscheduler to
fail with no regard to the RLIMIT_RTPRIO value the following check is made:

               /* can't increase priority */
                if (policy != SCHED_NORMAL &&
                    param->sched_priority > p->rt_priority &&
                    param->sched_priority >
                                p->signal->rlim[RLIMIT_RTPRIO].rlim_cur)
                        return -EPERM;

Thus I do believe that the RLIMIT_RTPRIO value must be taken into
account for the policy check, especially as the RLIMIT_RTPRIO limit is
of no use without this change.

The attached patch fixes this problem.

[PATCH] acpi: Don't call acpi_sleep_prepare from acpi_power_off

Now that all of the code paths that call acpi_power_off
have been modified to call either call kernel_power_off
(which calls apci_sleep_prepare by way of acpi_shutdown)
or to call acpi_sleep_prepare directly it is redundant to call
acpi_sleep_prepare from acpi_power_off.

So simplify the code and simply don't call acpi_sleep_prepare.

In addition there is a little error handling done so if we
can't register the acpi class we don't hook pm_power_off.

I think I have done the right thing with the CONFIG_PM define
but I'm not certain.  Can this code even be compiled if
CONFIG_PM is false?

[PATCH] ARM: 2819/1: Fix several S3C24x0 IIS defines

Patch from Dimitry Andric

- Change S3C2440_IISCON_MPLL to S3C2440_IISMOD_MPLL:
  The S3C2440 IISCON register doesn\'t control the master clock selection, this is done with the IISMOD register.
- Correct S3C2410_IISMOD_256FS and S3C2410_IISMOD_384FS:
  This is set via bit 2 of IISMOD, not bit 1.
- Add S3C2410_IISCON_PSCEN (prescaler enable), for completeness\' sake.

Remove "noreplacement" kernel command line option.

It is no longer valid to not replace instructions, since we depend on
different behaviour depending on CPU capabilities.

If you need to limit the capabilities of the replacements (because the
boot CPU has features that non-boot CPU's do not have, for example), you
need to explicitly disable those capabilities that are not shared across
all CPU's.

For example, if your boot CPU has FXSR, but other CPU's in your system
do not, you need to use the "nofxsr" kernel command line, not disable
instruction replacement per se.

x86: use alternative instructions for fnsave/fxsave too

This one ends up using an inline asm format that claims to read memory
and then clobber it (rather than just write it directly), which made it
easier to use the existing "alternative_input()" infrastructure support.

Now the fxsave code matches the fxrstor.

[PKT_SCHED]: em_meta: Kill TCF_META_ID_{INDEV,SECURITY,TCVERDICT}

x86: make restore_fpu() use alternative assembler instructions

It's really just a single instruction, conditional on whether the CPU
supports FXSR or not, so implement it as such instead of making it a
function that queries FXSR dynamically.

This means that the instruction just gets automatically rewritten to the
correct one at boot-time.

Fix up incorrect "unlikely()" on %gs reload in x86 __switch_to

These days %gs is normally the TLS segment, so it's no longer zero.  As
a result, we shouldn't just assume that %fs/%gs tend to be zero
together, but test them independently instead.

Also, fix setting of debug registers to use the "next" pointer instead
of "current".  It so happens that the scheduler will have set the new
current pointer before calling __switch_to(), but that's just an
implementation detail.
