According to Petr Vandrovec:

 ... "What is important (and checked) is address of MMCONFIG reported by MCFG
 table...  Unfortunately code does not bother with printing that address :-(

 "Another problem is that code has hardcoded that MMCONFIG area is 256MB large.
 Unfortunately for the code PCI specification allows any power of two between 2MB
 and 256MB if vendor knows that such amount of busses (from 2 to 128) will be
 sufficient for system.  With notebook it is quite possible that not full 8 bits
 are implemented for MMCONFIG bus number."

So here is a patch.  Unfortunately my system still fails the test because
it doesn't reserve any part of the MMCONFIG area, but this may fix others.

Booted on x86_64, only compiled on i386.  x86_64 still remaps the max area
(256MB) even though only 2MB is checked... but 2.6.16 had no check at all
so it is still better.

PCI: reduce size of x86 MMCONFIG reserved area check

1.  Print the address of the MMCONFIG area when the test for that area
    being reserved fails.

2.  Only check if the first 2MB is reserved, as that is the minimum.

[CPUFREQ] Make powernow-k7 work on SMP kernels.
Even though powernow-k7 doesn't work in SMP environments,
it can work on an SMP configured kernel if there's only
one CPU present, however recalibrate_cpu_khz was returning
-EINVAL on such kernels, so we failed to init the cpufreq driver.

memory hotplug: solve config broken: undefined reference to `online_page'

2006-07-25T03:35:20+00:00

Memory hotplug code of i386 adds memory to only highmem.  So, if
CONFIG_HIGHMEM is not set, CONFIG_MEMORY_HOTPLUG shouldn't be set.
Otherwise, it causes compile error.

In addition, many architecture can't use memory hotplug feature yet.  So, I
introduce CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG.

[PATCH] powerpc: Fix 64k pages on non-partitioned machines

2006-06-17T17:56:24+00:00

The page size encoding passed to tlbie is incorrect for new-style
large pages.  This fixes it.  This doesn't affect anything on older
machines because mmu_psize_defs[psize].penc (the page size encoding)
is 0 for 4k and 16M pages (the two are distinguished by a separate "is
a large page" bit).

From: Randy Dunlap 

According to include/asm-alpha/bitops.h, only ALPHA_EV67 has hardware
hweight support, so ALPHA_EV6 needs to use GENERIC_HWEIGHT.
