2009-05-16ACPI: Idle C-states disabled by max_cstate should not disable the TSCLen Brown
Processor idle power states C2 and C3 stop the TSC on many machines. Linux recognizes this situation and marks the TSC as unstable: Marking TSC unstable due to TSC halts in idle But if those same machines are booted with "processor.max_cstate=1", then there is no need to validate C2 and C3, and no need to disable the TSC, which can be reliably used as a clocksource.

A previous 2.6.30 patch, a71e4917dc0ebbcb5a0ecb7ca3486643c1c9a6e2, (ACPI: idle: mark_tsc_unstable() at init-time, not run-time) erroneously disabled the TSC on systems that did not actually have valid deep C-states.

2009-05-15libata: Media rotation rate and form factor heuristicsMartin K. Petersen
This patch provides new heuristics for parsing both the form factor and media rotation rate ATA IDENFITY words. The reported ATA version must be 7 or greater and the device must return values defined as valid in the standard. Only then are the characteristics reported to SCSI via the VPD B1 page. This seems like a reasonable compromise to me considering that we have been shipping several kernel releases that key off the rotation rate bit without any version checking whatsoever.

2009-05-15sysrq, intel_fb: fix sysrq g collisionJason Wessel
Commit 79e539453b34e35f39299a899d263b0a1f1670bd introduced a regression where you cannot use sysrq 'g' to enter kgdb. The solution is to move the intel fb sysrq over to V for video instead of G for graphics. The SMP VOYAGER code to register for the sysrq-v is not anywhere to be found in the mainline kernel, so the comments in the code were cleaned up as well. This patch also cleans up the sysrq definitions for kgdb to make it generic for the kernel debugger, such that the sysrq 'g' can be used in the future to enter a gdbstub or another kernel debugger.

2009-05-14drm/i915: ignore LVDS on intel graphics systems that lie about having itJarod Wilson
There are a number of small form factor desktop systems with Intel mobile graphics chips that lie and say they have an LVDS. With kernel mode-setting, this becomes a problem, and makes native resolution boot go haywire -- for example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080 display uses only the top left 1024x768, and auto-configured X will end up only 1024x768 as well. With this change, graphical boot and X both do 1920x1080 as expected. Note that we're simply embracing and extending the early bail-out code in place for the Mac Mini here. The xorg intel driver uses pci subsystem device and vendor id for matching, while we're using dmi lookups here. The MSI addition is courtesy of and tested by Bill Nottingham.

2009-05-14drm/i915: sanity check IER at wait_request timeJesse Barnes
We might sleep here anyway so I hope an extra uncached read is ok to add. In #20896 we found that vbetool clobbers the IER. In KMS mode this is particularly bad since we don't set the interrupt regs late (in EnterVT), so we'd fail to get *any* interrupts at all after X started (since some distros have scripts that call vbetool at X startup apparently). So this patch checks IER at wait_request time, and re-enables interrupts if it's been clobbered. In a proper config this check should never be triggered. This is really a distro issue, but having a sanity check is nice, as long as it doesn't have a real performance hit.

Preset 1 is the default setting with default clocks and voltage. The new eeepc-laptop driver doesn't support it anymore. The attached patch adds support for it to eeepc-laptop.

2009-05-14eeepc-laptop: Work around rfkill firmware bugAlan Jenkins
1) Buggy firmware can change the RFKILL state by itself. This is easily detected. The RFKILL API states that in such cases, we should call rfkill_force_state() to notify the core. I have reported the bug to Asus. I believe this is the right thing to do for robustness, even if this particular firmware bug is fixed. 2) The same bug causes the wireless toggle key to be reported as 0x11 instead of 0x10. 0x11 is otherwise unused, so it should be safe to add this as a new keycode. The bug is triggered by removing the laptop battery while hibernated. On resume, the wireless toggle key causes the firmware to toggle the wireless state itself. (Also, the key is reported as 0x11 when the current wireless state is OFF). This is very poor behaviour because the OS can't predict whether the firmware is controlling the RFKILL state. Without this workaround, the bug means users have to press the wireless toggle key twice to enable, due to the OS/firmware conflict. (Assuming rfkill-input or equivalent is being used). The workaround avoids this. I believe that acpid scripts which toggle the value of the sysfs state file when the toggle key is pressed will be rendered ineffective by the bug, regardless of this workaround. If they simply toggle the state, when the firmware has already toggled it, then you will never see a state change. Tested on "EEEPC 4G" only.

2009-05-14eeepc-laptop: fix wlan rfkill state change during initAlan Jenkins
When an rfkill device is registered, the rfkill core will change its state to the system default. So we need to prepare for state changes *before* we register it. That means installing the eeepc-specific ACPI callback which handles the hotplug of the wireless network adaptor. This problem doesn't occur during normal operation. You have to 1) Boot with wireless enabled. eeepc-laptop should load automatically. 2) modprobe -r eeepc-laptop 3) modprobe eeepc-laptop On boot, the default rfkill state will be set to enabled. With the current core code, step 2) will disable the wireless. Therefore in step 3), the wireless will change state during registration, from disabled to enabled. But without this fix, the PCI device for the wireless adaptor will not appear.

as reported by Alexander Beregalov <a.beregalov@gmail.com> ioatdma 0000:00:08.0: DMA-API: device driver frees DMA memory with wrong function [device address=0x000000007f76f800] [size=2000 bytes] [map ped as single] [unmapped as page] The ioatdma driver was unmapping all regions (either allocated as page or single) using unmap_page. This patch lets dma driver recognize if unmap_single or unmap_page should be used. It introduces two new dma control flags: DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE. They should be set to indicate dma driver to do dma-unmapping as single (first one for the source, tha latter for the destination). If respective flag is not set, the driver assumes dma-unmapping as page.

2009-05-12viafb: make it work on x86_64Harald Welte
Fix a bug in viafb on x86_64 builds (e.g. for VIA Nano CPU). You cannot make the assumption that sizeof(unsigned int) == sizeof(unsigned long), so the parsing of the default mode (640x480) fails, leading to a division by zero during insmod of the driver.

2009-05-12fbdev: remove outdated advice about I2C configurationJean Delvare
The required I2C modules are now selected automatically by the means of select statements in Kconfig, so there is no point in confusing the users with options he/she would be supposed to enable manually.
