[PATCH] time interpolator: Fix settimeofday inaccuracy

settimeofday will set the time a little bit too early on systems using
time interpolation since it subtracts the current interpolator offset
from the time. This used to be necessary with the code in 2.6.9 and earlier
but the new code resets the time interpolator after setting the time.
Thus the time is set too early and gettimeofday will return a time slightly
before the time specified with settimeofday if invoked immeditely after
settimeofday.

This removes the obsolete subtraction of the time interpolator offset
and makes settimeofday set the time accurately.

Patch from Deepak Saxena

The current memset() and memzero() macros on ARM reference the
incoming parameters more than once and this can cause uninted
side-effects. The issue was found while debugging SCTP protocol
and with the specific usage of memzero(skb_put(skb,size),size).
This call would call skb_put(skb,size) twice leading to badness.

variables and uses those instead.

[TG3]: Fix tg3_restart_ints()

tg3_restart_ints() is called to re-enable interrupts after tg3_poll()
has finished all the work. It calls tg3_cond_int() to force an interrupt
if the status block updated bit is set. The updated bit will be set if
there is a new status block update sometime during tg3_poll() and it can
be very often. The worst part is that even if all the work has been
processed, the updated bit remains set and an interrupt will be forced
unnecessarily.

The fix is to call tg3_has_work() instead to determine if new work is
posted before forcing an interrupt. The way to force an interrupt is
also changed to use "coalesce_now" instead of "SETINT". The former is
generally a safer way to force the interrupt.

Also deleted the first parameter to tg3_has_work() which is unused.

[TG3]: Fix bug in tg3_rx()

This patch fixes a bug that causes tg3_has_work() to always return 1.

rx work is determined by comparing tp->rx_rcb_ptr with the current hw
producer index. The hw producer index is modulo the ring size, but tp-
>rx_rcb_ptr is a free running counter that goes up beyond the ring size.
After the ring wraps around once, tg3_has_work() will always return 1.

The fix is to always do modulo arithmetic on tp->rx_rcb_ptr.

[PATCH] ARM: 2644/1: Adds S3C2400 support to uncompress.h

Patch from Lucas Correia Villa Real

The S3C2400 doesn't have a cpuid information stored anywhere. This patch adds
support to the S3C2400 at include/asm-arm/arch-s3c2400/uncompress.h by
initializing the cpuid variable to the S3C2410, as they share the same

[IA64] fix ia64 Kconfig to allow CONFIG_PM on sn2

This probably should have been fixed when I fixed up the generic build for
discontig+numa machines, but oh well.

CONFIG_PM is allowable for generic builds but not for sn2 builds, which
doesn't make much sense, and in fact breaks the build if recent ACPI bits are
added to the tree.  It looks like the only arch that needs to prevent
CONFIG_PM stuff is the ski simulator (though those options could probably use
some cleanup as well), so remove the big conditional and replace it with a
simple test for IA64_HP_SIM instead.

[IA64] vector sharing (Large I/O system support)

Current ia64 linux cannot handle greater than 184 interrupt sources
because of the lack of vectors. The following patch enables ia64 linux
to handle greater than 184 interrupt sources by allowing the same
vector number to be shared by multiple IOSAPIC's RTEs. The design of
this patch is besed on "Intel(R) Itanium(R) Processor Family Interrupt
Architecture Guide".

Even if you don't have a large I/O system, you can see the behavior of

[IA64] fix syscall-optimization goof

Sadly, I goofed in this syscall-tuning patch:

ChangeSet 1.1966.1.40 2005/01/22 13:31:05 davidm@hpl.hp.com
  [IA64] Improve ia64_leave_syscall() for McKinley-type cores.

  Optimize ia64_leave_syscall() a bit better for McKinley-type cores.
  The patch looks big, but that's mostly due to renaming r16/r17 to r2/r3.
  Good for a 13 cycle improvement.

The problem is that the size of the physical stacked registers was
loaded into the wrong register (r3 instead of r17).  Since r17 by
coincidence always had the value 1, this had the effect of turning
rse_clear_invalid into a no-op.  That poses the risk of leaking kernel
state back to user-land and is hence not acceptable.

The fix below is simple, but unfortunately it costs us about 28 cycles
in syscall overhead. ;-(

Unfortunately, there isn't much we can do about that since those
registers have to be cleared one way or another.
