From: Oleg Drokin: This patch is needed to support kernel modules that want to use clear_user() (that is exported symbol on all other architectures).

Byte-swapping of the port and IP address passed in to the multicast driver by the user used to happen in different places, which was a bug in itself. The port also was swapped before being printk-ed, which led to a misleading message. This patch moves the port swapping to the same place as the IP address swapping. It also cleans up the error paths of mcast_open.

Some changes that I sent in didn't make 2.6.12-rc4 for some reason. This adds them back. We have an x86_64 definition of TOP_ADDR 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.

The recent change to add a timeout to strbuf flushing had a negative performance impact. The udelay()'s are too long, and they were done in the wrong order wrt. the register read checks. Fix both, and things are happy again. There are more possible improvements in this area. In fact, PCI streaming buffer flushing seems to be part of the bottleneck in network receive performance on my SunBlade1000 box. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Recently the __copy_tofrom_user routine was modified to avoid doing prefetches past the end of the source array.

On ppc32, the platform code can supply a "progress" function that is used to show progress through the boot. These functions are usually in an init section and so can't be called after the init pages are freed. Now that the cpu bringup code can be called after the system is booted (for hotplug cpu) we can get the situation where the progress function can be called after boot. The simple fix is to set the progress function pointer to NULL when the init pages are freed, and that is what this patch does (note that all callers already check whether the function pointer is NULL before trying to call it).

This patch removes the assumption that LAPIC entries contain the BSP as its first entry. This is a slight improvement to the temporary fix submitted by Suresh Siddha. - Removes assumption that LAPIC entries contain BSP first. - Builds x86_acpiid_to_apicid[] and bios_cpu_apicid[] properly with BSP as first entry. - Made maxcpus=1 boot on these systems. Since the parsing earlier in arch/x86_64/kernel/mpparse.c stopped after maxcpus entries, other entries were not processed, this causes kernel not to boot on these systems. TBD: x86_acpiid_to_apicid and bios_cpu_apicid[] seem to be exactly the same. This could be removed, but might need more work to cleanup.

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 Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

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.

The new TSC sync algorithm recently submitted did not work too well. The result was that some MP machines where the TSC came up of the BIOS very unsynchronized and that did not have HPET support were nearly unusable because the time would jump forwards and backwards between CPUs. After a lot of research ;-) and some more prototypes I ended up with just using the one from IA64 which looks best. It has some internal self tuning that should adapt to changing interconnect latencies. It holds up in my tests so far. I believe it was originally written by David Mosberger, I just ported it over to x86-64. See the inline comment for a description. This cleans up the code because it uses smp_call_function for syncing instead of having custom hooks in SMP bootup. Please note that the cycle numbers it outputs are too optimistic because they do not take into account the latency of WRMSR and RDTSC, which can be hundreds of cycles. It seems to be able to sync a dual Opteron to 200-300 cycles, which is probably good enough. There is a timing window during AP bootup where interrupts can see inconsistent time before the TSC is synced. It is hard to avoid unfortunately because we can only do the TSC sync after some setup, and we need to enable interrupts before that. I just ignored it for now.

This prevents funny /proc/cpuinfo output - Do the same with phys_proc_id[] even when no HyperThreading - dito. - Use the CPU APIC-ID from CPUID 1 instead of the linux virtual CPU number to identify the core for AMD dual core setups.
