2008-09-22x86: fix CONFIG_X86_RESERVE_LOW_64K=yYinghai Lu
The bad_bios_dmi_table() quirk never triggered because we do DMI setup too late. Move it a bit earlier. Also change the CONFIG_X86_RESERVE_LOW_64K quirk to operate on the e820 table directly instead of messing with early reservations - this handles overlaps (which do occur in this low range of RAM) more gracefully.

2008-09-22x86: use round_jiffies() for the corruption check timerArjan van de Ven

2008-09-22avr32: Use platform_driver_probe for pdc platform driverUwe Kleine-König
The probe function of the pdc platform driver lives in the init section and so a pdc device that is created after the init section is discarded probably results in an oops. Even if this cannot happen, using platform_driver_probe is cleaner. (If this can happen and should be supported the probe function must live in the devinit section instead.)

2008-09-22avr32: Provide a way to deselect pins in the portmuxHaavard Skinnemoen
Currently, setting up the portmux is completely one-shot: Once a pin is muxed, the portmux driver will complain loudly and refuse to do anything if you try to set up the same pin again. Sometimes, it may be necessary to change the configuration of a pin after it has been set up initially. This patch adds a way to undo the previous configuration, allowing the pin to be reconfigured.

2008-09-22ngw100: export J15 through sysfsDavid Brownell
The NGW100 board has jumper J15 (near the reset button) which is unused. This patch exports it through the GPIO sysfs support (as /sys/class/gpio/gpio62/value) so that it's easily queried by boot scripts or whatever might want to know if the jumper has been installed (value = 0) or not (value = 1, "default").

This patch adds backtracing capability to oprofile profiling in kernel and user mode on AVR32. This is done by going through the frames on the stack and adding oprofile traces for all return addresses. The code being profiled has to be compiled with frame pointers to make this work.

2008-09-21[ARM] 5264/2: [AT91] Suspend-to-RAM disables main oscillatorAndrew Victor
This patch adds support for a low(er)-power suspend-to-RAM. In addition to the SDRAM being put into self-refresh mode, the Master Clock is set to the Slow-clock rate (32Khz) and PLLA & PLLB are disabled. Certain peripherals are therefore also disabled, and thus cannot be used as wakeup sources. This patch has been included in the AT91 patches in various forms since 2.6.19 and a number of people have worked or commented on it, most notably: Savin Zlobec (for the original AT91RM9200 support) Anti Sullin (for the SAM9260 version) David Brownell, etc. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-09-20sparc64: Fix disappearing PCI devices on e3500.David S. Miller
Based upon a bug report by Meelis Roos. The OF device layer builds properties by matching bus types and applying 'range' properties as appropriate, up to the root. The match for "PCI" busses is looking at the 'device_type' property, and this does work %99 of the time. But on an E3500 system with a PCI QFE card, the DEC 21153 bridge sitting above the QFE network interface devices has a 'name' of "pci", but it completely lacks a 'device_type' property. So we don't match it as a PCI bus, and subsequently we end up with no resource values at all for the devices sitting under that DEC bridge. Signed-off-by: David S. Miller <davem@davemloft.net>
