We fixed this bug before, but it didn't take. It may have been the case
that the problem was first noticed to occur in a CONFIG_REGPARM compile.
But it's not regparm functions that need not to make tail calls, it's
asmlinkage functions called with a user pt_regs frame on the stack
supplying their arguments. prevent_tail_call probably doesn't do anything
at all in regparm functions (your argument registers are going to be
clobbered, period). It was a braino to conditionalize that definition in
the first place.

Here is a fixed up version of the reorder feature of netem.
It is the same as the earlier patch plus with the bugfix from Julio merged in.
Has expected backwards compatibility behaviour.
Go ahead and merge this one, the TCP strangeness I was seeing was due
to the reordering bug, and previous version of TSO patch.

For quite a while, there has existed a hypervisor bug on legacy iSeries
which means that we do not get the boot time set in the kernel. This
patch works around that bug. This was most noticable when the root
partition needed to be checked at every boot as the kernel thought it
was some time in 1905 until user mode reset the time correctly.

Older UltraSPARC-III chips have a P-Cache bug that makes us disable it
by default at boot time.
However, this does hurt performance substantially, particularly with
memcpy(), and the bug is _incredibly_ obscure. I have never seen it
triggered in practice, ever.
So provide a "-P" boot option that forces the P-Cache on. It taints
the kernel, so if it does trigger and cause some data corruption or
OOPS, we will find out in the logs that this option was on when it
happened.

In _spin_unlock_bh(lock):
do { \
_raw_spin_unlock(lock); \
preempt_enable(); \
local_bh_enable(); \
__release(lock); \
} while (0)
there is no reason for using preempt_enable() instead of a simple
preempt_enable_no_resched()
Since we know bottom halves are disabled, preempt_schedule() will always
return at once (preempt_count!=0), and hence preempt_check_resched() is
useless here...
This fixes it by using "preempt_enable_no_resched()" instead of the
"preempt_enable()", and thus avoids the useless preempt_check_resched()
just before re-enabling bottom halves.

Some changes that I sent in didn't make 2.6.12-rc4 for some reason. This
adds them back. We have

a reimplementation of the x86_64 csum_partial_copy_from_user
some syntax fixes in arch/um/kernel/ptrace.c
removal of a CFLAGS definition in the x86_64 Makefile
some include changes in the x86_64 ptrace.c and user-offsets.h
a syntax fix in elf-x86_64.h
Also moved an include in the i386 and x86_64 Makefiles to make the symlinks
work, and some small fixes from Al Viro.

There's a basic need not to have parameters go under or over certain
values when doing domain validation. The basic ones are
max_offset, max_width and min_period
This patch makes the transport class take and enforce these three
limits. Currently they can be set by the user, although they could
obviously be read from the HBA's on-board NVRAM area during
slave_configure (if it has one).

The driver model has a "detach_state" mechanism that:
- Has never been used by any in-kernel drive;
- Is superfluous, since driver remove() methods can do the same thing;
- Became buggy when the suspend() parameter changed semantics and type;
- Could self-deadlock when called from certain suspend contexts;
- Is effectively wasted documentation, object code, and headspace.
This removes that "detach_state" mechanism; net code shrink, as well
as a per-device saving in the driver model and sysfs.

Collected NMI watchdog fixes.
- Fix call of check_nmi_watchdog
- Remove earlier move of check_nmi_watchdog to later. It does not fix the
race it was supposed to fix fully.
- Remove unused P6 definitions
- Add support for performance counter based watchdog on P4 systems.
This allows to run it only once per second, which saves some CPU time.
Previously it would run at 1000Hz, which was too much.
Code ported from i386
Make this the default on Intel systems.
- Use check_nmi_watchdog with local APIC based nmi
- Fix race in touch_nmi_watchdog
- Fix bug that caused incorrect performance counters to be programmed in a
few cases on K8.
- Remove useless check for local APIC
- Use local_t and per_cpu variables for per CPU data.
- Keep other CPUs busy during check_nmi_watchdog to make sure they really
tick when in lapic mode.
- Only check CPUs that are actually online.
- Various other fixes.
- Fix fallback path when MSRs are unimplemented

There are unfortunately more and more multi processor Opteron systems which
don't have HPET timer support in the southbridge. This covers in particular
Nvidia and VIA chipsets. They also don't guarantee that the TSCs are
synchronized between CPUs; and especially with MP powernow the systems are
nearly unusable because the time gets very inconsistent between CPUs.
The timer code for x86-64 was originally written under the assumption that we
could fall back to the HPET timer on such systems. But this doesn't work
there.
Another alternative is to use the ACPI PM timer as primary time source. This
patch does that. The kernel only uses PM timer when there is no other choice
because it has some disadvantages.
Ported over from i386. It should be faster than the i386 version because I
dropped the "read three times" workaround, but is still considerable slower
than HPET and also does not work together with vsyscalls which have to be
disabled.
