2007-05-16[ARM] Remove Integrator/CP SMP platform supportRussell King
The Integrator/CP SMP platform support was never fully merged, and now it's causing build breakage. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-05-14Revert "ipmi: add new IPMI nmi watchdog handling"Linus Torvalds
This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53. Andi Kleen is unhappy with the changes, and they really do not seem worth it. IPMI could use DIE_NMI_IPI instead of the new callback, even though that ends up having its own set of problems too, mainly because the IPMI code cannot really know the NMI was from IPMI or not. Manually fix up conflicts in arch/x86_64/kernel/traps.c and drivers/char/ipmi/ipmi_watchdog.c.

2007-05-13[CPUFREQ] powernow-k7: fix MHz rounding issue with perflibDaniel Drake
When the PST tables are broken, powernow-k7 uses ACPI's processor_perflib to deduce the available frequency multipliers from the _PSS tables. Upon frequency change, processor_perflib performs some verification on the frequency (checks that it's within allowable bounds). powernow-k7 deals with absolute frequencies in KHz, whereas perflib only deals with MHz values. When performing the above verification, perflib multiplies the MHz values by 1000 to obtain the KHz value. We then end up with situations like the following: - powernow-k7 multiplies the multiplier by the FSB, and obtains a value such as 1266768 KHz - perflib belives the same state has frequency of 1266 MHz - acpi_processor_ppc_notifier calls cpufreq_verify_within_limits to verify that 1266768 is in the allowable range of 0 to 1266000 (i.e. 1266 * 1000) - it's not, so that frequency is rejected - the maximum CPU frequency is not reachable This patch solves the problem by rounding up the MHz values stored in perflib's tables. Additionally it corrects a broken URL. It also fixes http://bugzilla.kernel.org/show_bug.cgi?id=8255 although this case is a bit different: the frequencies in the _PSS tables are wildly wrong, but we get better results if we force ACPI to respect the fsb * multiplier calculations (even though it seems that the multiplier values aren't entirely correct either).

2007-05-12SLUB: i386 supportChristoph Lameter
SLUB cannot run on i386 at this point because i386 uses the page->private and page->index field of slab pages for the pgd cache. Make SLUB run on i386 by replacing the pgd slab cache with a quicklist. Limit the changes as much as possible. Leave the improvised linked list in place etc etc. This has been working here for a couple of weeks now.

2007-05-12[POWERPC] Add bootwrapper support for Motorola PrPMC2800 platformMark A. Greer
The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or PrPMC2800 baseboard, respectively. There are several variants of each type of processor module which can have different amounts of memory, amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362. The bootwrapper code for that platform reads VPD from an I2C EEPROM to determine the processor module variant. From the variant, the amount of memory, etc. is determined and the device tree is updated accordingly. If the variant cannot be determined (e.g., corrupted VPD or a previously unknown variant), the property values already in the device tree are used. Also, the firmware for those platforms does not completely configure the mv64x60 host bridge so that configuration is done here. Signed-off-by: Mark A.

2007-05-12[POWERPC] Add DTS file for the Motorola PrPMC2800 platformMark A. Greer
Add the device tree source file for the prpmc2800 line of processor PMCs. Several of the property values are updated by the bootwrapper but sane defaults have been chosen in case the bootwrapper can't determine the exact processor board variant.
