1b61b910e9 [PATCH] x86: kernel irq balance doesn't work
On i386, kernel irq balance doesn't work.

1) In function do_irq_balance, after kernel finds the min_loaded cpu but
   before calling set_pending_irq to really pin the selected_irq to the
   target cpu, kernel does a cpus_and with irq_affinity[selected_irq].
   Later on, when the irq is acked, kernel would calls
   move_native_irq=>desc->handler->set_affinity to change the irq affinity.
    However, every function pointed by
   hw_interrupt_type->set_affinity(unsigned int irq, cpumask_t cpumask)
   always changes irq_affinity[irq] to cpumask.  Next time when recalling
   do_irq_balance, it has to do cpu_ands again with
   irq_affinity[selected_irq], but irq_affinity[selected_irq] already
   becomes one cpu selected by the first irq balance.

2) Function balance_irq in file arch/i386/kernel/io_apic.c has the same
   issue.

ba528f2854 [PATCH] fix x86 microcode driver handling of multiple matching revisions
When multiple updates matching a given CPU are found in the update file, the
action taken by the microcode update driver was inappropriate:

- when lower revision microcode was found before matching or higher revision
  one, the driver would needlessly complain that it would not downgrade the
  CPU
- when microcode matching the currently installed revision was found before
  newer revision code, no update would actually take place

To change this behavior, the driver now concludes about possibly updates and
issues messages only when the entire input was parsed.

Additionally, this adds back (in different places, and conditionalized upon
a new module option) some messages removed by a previous patch.

get the mail directly.

anymore (as far as I know, nobody has ever damaged a CPU with this
driver).

d44647b0a6 [PATCH] Fix HPET operation on 32-bit NVIDIA platforms
From: "Andy Currid" <ACurrid@nvidia.com>

This patch fixes a kernel panic during boot that occurs on NVIDIA platforms
that have HPET enabled.

When HPET is enabled, the standard timer IRQ is routed to IOAPIC pin 2 and is
advertised as such in the ACPI APIC table - but an earlier workaround in the
kernel was ignoring this override.  The fix is to honor timer IRQ overrides
from ACPI when HPET is detected on an NVIDIA platform.

be0d03f1c3 [PATCH] i386 kdump boot cpu physical apicid fix
o Kdump second kernel boot fails after a system crash if second kernel
  is UP and acpi=off and if crash occurred on a non-boot cpu.

o Issue here is that MP tables report boot cpu lapic id as 0 but second
  kernel is booting on a different processor and MP table data is stale
  in this context. Hence apic_id_registered() check fails in setup_local_APIC()
  when called from APIC_init_uniprocessor().

o Problem is not seen if ACPI is enabled as in that case
  boot_cpu_physical_apicid is read from the LAPIC.

o Problem is not seen with SMP kernels as well because in this case also
  boot_cpu_physical_apicid is read from LAPIC. (smp_boot_cpus()).

o The problem is fixed by reading boot_cpu_physical_apicid from LAPIC
  if it is a UP kernel and CRASH_DUMP is enabled.

e0c1e9bf81 [PATCH] x86_64: avoid IRQ0 ioapic pin collision
The patch addresses a problem with ACPI SCI interrupt entry, which gets
re-used, and the IRQ is assigned to another unrelated device.  The patch
corrects the code such that SCI IRQ is skipped and duplicate entry is
avoided.  Second issue came up with VIA chipset, the problem was caused by
original patch assigning IRQs starting 16 and up.  The VIA chipset uses
4-bit IRQ register for internal interrupt routing, and therefore cannot
handle IRQ numbers assigned to its devices.  The patch corrects this
problem by allowing PCI IRQs below 16.

We only need to check cpu_has_apic in the IO-APIC/L-APIC parsing, not for
all of ACPI.

42e4c8585f [PATCH] i386: Remove apic= warning
The apic= option can be used to set the APIC driver too.  When that is done
this code would always produce bogus warnings.

The patch I submitted earlier to fix disabled LAPIC handling in ACPI was
mismerged for some reason I still don't quite understand.  Parts of it was
applied to the wrong function.

This patch fixes it up.
