Eric Sandeen 4961f10e22 [PATCH] x86_64: (resend) x86_64 stack overflow debugging
Take two, now without spurious whitespace :(  Applies to git & 2.6.17-rc6

CONFIG_DEBUG_STACKOVERFLOW existed for x86_64 in 2.4, but seems to have gone AWOL in 2.6.

I've pretty much just copied this over from the 2.4 code, with
appropriate tweaks for the 2.6 kernel, plus a bugfix.  I'd personally
rather see it printed out the way other arches do it, i.e.
bytes-remaining-until-overflow, rather than having to do the subtraction
yourself.  Also, only 128 bytes remaining seems awfully late to issue a
warning.  But I'll start here :)

Venkatesh Pallipadi 0080e66755 [PATCH] x86_64: i386/x86-64 Add nmi watchdog support for new Intel CPUs
Intel now has support for Architectural Performance Monitoring Counters
( Refer to IA-32 Intel Architecture Software Developer's Manual
http://www.intel.com/design/pentium4/manuals/253669.htm ). This
feature is present starting from Intel Core Duo and Intel Core Solo processors.

What this means is, the performance monitoring counters and some performance
monitoring events are now defined in an architectural way (using cpuid).
And there will be no need to check for family/model etc for these architectural
events.

Below is the patch to use this performance counters in nmi watchdog driver.
Patch handles both i386 and x86-64 kernels.

Keith Owens e77deacb7b [PATCH] x86_64: Avoid broadcasting NMI IPIs
On some i386/x86_64 systems, sending an NMI IPI as a broadcast will
reset the system.  This seems to be a BIOS bug which affects machines
where one or more cpus are not under OS control.  It occurs on HT
systems with a version of the OS that is not compiled without HT
support.  It also occurs when a system is booted with max_cpus=n where
2 <= n < cpus known to the BIOS.  The fix is to always send NMI IPI as
a mask instead of as a broadcast.

From SDM Vol-3A "Valid Interrupt Vectors" section:
	"When an illegal vector value (0-15) is written to an LVT entry
	and the delivery mode is Fixed, the APIC may signal an illegal
	vector error, with out regard to whether the mask bit is set
	or whether an interrupt is actually seen on input."

Keith Owens 45486f81c9 [PATCH] x86_64: Standardize i386/x86_64 handling of NMI_VECTOR
x86_64 and i386 behave inconsistently when sending an IPI on vector 2
(NMI_VECTOR).  Make both behave the same, so IPI 2 is sent as NMI.

The crash code was abusing send_IPI_allbutself() by passing a code
instead of a vector, it only worked because crash knew about the
internal code of send_IPI_allbutself().  Change crash to use NMI_VECTOR
instead, and remove the comment about how crash was abusing the function.

This patch is a pre-requisite for fixing the problem where sending an
IPI as NMI would reboot some Dell Xeon systems.  I cannot fix that
problem while crash continus to abuse send_IPI_allbutself().

It also removes the inconsistency between i386 and x86_64 for
NMI_VECTOR.  That will simplify all the RAS code that needs to bring
all the cpus to a clean stop, even when one or more cpus are spinning
disabled.

Sergey Vlasov 409f89e0ef [PATCH] x86_64: Do not use -ffunction-sections for modules
Currently CONFIG_REORDER uses -ffunction-sections for all code;
however, creating a separate section for each function is not useful
for modules and just adds bloat.  Moving this option from CFLAGS to
CFLAGS_KERNEL shrinks module object files (e.g., the module tree for a
kernel built with most drivers as modules shrinked from 54M to 46M),
and decreases the number of sysfs files in /sys/module/*/sections/
directories.

Andi Kleen 495ab9c045 [PATCH] i386/x86-64/ia64: Move polling flag into thread_info_status
During some profiling I noticed that default_idle causes a lot of
memory traffic. I think that is caused by the atomic operations
to clear/set the polling flag in thread_info. There is actually
no reason to make this atomic - only the idle thread does it
to itself, other CPUs only read it. So I moved it into ti->status.

Converted i386/x86-64/ia64 for now because that was the easiest
way to fix ACPI which also manipulates these flags in its idle
function.

After writing the CFG register, the first value written to the T0_CMP
register is the value at which next interrupt should be triggered, every
value after that sets the period of the interrupt. For that reason, the code
needs to write the value twice - to set both the phase and period.

[AK: I had already figured it out by myself, but it's still useful
to have a comment for this.]

Vojtech Pavlik 4221133845 [PATCH] x86_64: Make use of the *PER* constants in time.c
This patch makes use of the newly added conversion constants
in time.h to x86-64 time.c. The code gets significantly easier
to understand.

Vojtech Pavlik e30db3e699 [PATCH] x86_64: Remove hack to manually enable HPET on AMD8111 southbridges
Remove #ifdefed code to manually enable HPET on AMD8111, where the
BIOS doesn't have ACPI HPET tables and doesn't enable it for us.

This patch adds the X86_FEATURE_RDTSCP #define, so that kernel code can
check for the feature easily and also fixes the location of the "rdtscp"
string in the cpuinfo tables.

Rohit Seth f3fa8ebc25 [PATCH] x86_64: moving phys_proc_id and cpu_core_id to cpuinfo_x86
Most of the fields of cpuinfo are defined in cpuinfo_x86 structure.
This patch moves the phys_proc_id and cpu_core_id for each processor to
cpuinfo_x86 structure as well.

Jon Mason e465058d55 [PATCH] x86_64: Calgary IOMMU - Calgary specific bits
This patch hooks Calgary into the build, the x86-64 IOMMU
initialization paths, and introduces the Calgary specific bits.  The
implementation draws inspiration from both PPC (which has support for
the same chip but requires firmware support which we don't have on
x86-64) and gart. Calgary is different from gart in that it support a
translation table per PHB, as opposed to the single gart aperture.

Changes from previous version:
 * Addition of boot-time disablement for bus-level translation/isolation
   (e.g, enable userspace DMA for things like X)
 * Usage of newer IOMMU abstraction functions

Jon Mason 0dc243ae10 [PATCH] x86_64: Calgary IOMMU - IOMMU abstractions
This patch creates a new interface for IOMMUs by adding a centralized
location for IOMMU allocation (for translation tables/apertures) and
IOMMU initialization.  In creating these, code was moved around for
abstraction, uniformity, and consiceness.

Take note of the move of the iommu_setup bootarg parsing code to
__setup.  This is enabled by moving back the location of the aperture
allocation/detection to mem init (which while ugly, was already the
location of the swiotlb_init).

While a slight departure from the previous patch, I belive this provides
the true intention of the previous versions of the patch which changed
this code.  It also makes the addition of the upcoming calgary code much
cleaner than previous patches.

[AK: Removed one broken change. iommu_setup still has to be called
early]

Jon Mason 8d4f6b93a4 [PATCH] x86_64: Calgary IOMMU - introduce iommu_detected
swiotlb relies on the gart specific iommu_aperture variable to know if
we discovered a hardware IOMMU before swiotlb initialization.  Introduce
iommu_detected to do the same thing, but in a HW IOMMU neutral manner,
in preparation for adding the Calgary HW IOMMU.
