| * x86: Remove "x86 CPU features in debugfs" (CONFIG_X86_CPU_DEBUG)H. Peter Anvin2010-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_X86_CPU_DEBUG, which provides some parsed versions of the x86 CPU configuration via debugfs, has caused boot failures on real hardware. The value of this feature has been marginal at best, as all this information is already available to userspace via generic interfaces. Causes crashes that have not been fixed + minimal utility -> remove. See the referenced LKML thread for more information. Reported-by: Ozan Çağlayan <ozan@pardus.org.tr> Signed-off-by: H.

| * Revert "x86: ucode-amd: Load ucode-patches once ..."Andreas Herrmann2010-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d1c84f79a6ba992dc01e312c44a21496303874d6 leads to a regression when microcode_amd.c is compiled into the kernel. It causes a big boot delay because the firmware is not available. See http://marc.info/?l=linux-kernel&m=126267290920060 It also renders the reload sysfs attribute useless. Fixing this is too intrusive for an -rc5 kernel. Thus I'd like to restore the microcode loading behaviour of kernel 2.6.32.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HPET MSI on platforms with ATI SB700/SB800 as they seem to have some side-effects on floppy DMA. Do not use HPET MSI on such platforms. Original problem report from Mark Hounschell http://lkml.indiana.edu/hypermail/linux/kernel/0912.2/01118.html [ This patch needs to go to stable as well.

| * x86: Set hotpluggable nodes in nodes_possible_mapDavid Rientjes2010-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nodes_possible_map does not currently include nodes that have SRAT entries that are all ACPI_SRAT_MEM_HOT_PLUGGABLE since the bit is cleared in nodes_parsed if it does not have an online address range. Unequivocally setting the bit in nodes_parsed is insufficient since existing code, such as acpi_get_nodes(), assumes all nodes in the map have online address ranges. In fact, all code using nodes_parsed assumes such nodes represent an address range of online memory. nodes_possible_map is created by unioning nodes_parsed and cpu_nodes_parsed; the former represents nodes with online memory and the latter represents memoryless nodes. We now set the bit for hotpluggable nodes in cpu_nodes_parsed so that it also gets set in nodes_possible_map. [ hpa: Haicheng Li points out that this makes the naming of the variable cpu_nodes_parsed somewhat counterintuitive. However, leave it as is in the interest of keeping the pure bug fix patch small. ] Signed-off-by: David Rientjes <rientjes@google.com> Tested-by: Haicheng Li <haicheng.li@linux.intel.com> LKML-Reference: <alpine.DEB.2.00.1001201152040.30528@chino.kir.corp.google.com> Cc: <stable@kernel.org> Signed-off-by: H.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kvm_handle_sie_intercept uses a jump table to get the intercept handler for a SIE intercept. Static code analysis revealed a potential problem: the intercept_funcs jump table was defined to contain (0x48 >> 2) entries, but we only checked for code > 0x48 which would cause an off-by-one array overflow if code == 0x48.

The vcpu can pick up the IRR and inject the interrupt before setting the TMR, and perhaps even EOI it, causing incorrect behaviour. The race is really insignificant since it can only occur on the first interrupt (usually following interrupts will not change TMR), but it's better closed than open.

This patch applies on top of Linus' current -git tree I've taken my best swing at converting this, but I'm not 100% confident I got it right. My cross-compiler is now out of date (gcc4.2) so I wasn't able to check if it compiled. Any assistance from arch maintainers or testers to get this merged would be great.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, DSS does not wakeup when there is a DMA request. DSS wake up event must be enabled so that the DMA request to refill the FIFO will wake up the CORE domain.

| | * | | | OMAP: timekeeping: time should not stop during suspendKevin Hilman2010-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During suspend, the kernel timekeeping subsystem is shut down. Before suspend and upon resume, it uses a weak function read_persistent_clock() to determine the amount of time that elapsed during suspend. This function was not implemented on OMAP, so from the timekeeping subsystem perspective (and thus userspace as well) it appeared that no time elapsed during suspend. This patch uses the 32k sync timer as a the persistent clock. NOTE: This does *NOT* fully handle wrapping of the 32k sync timer, so more than one wrapping of the 32k sync timer during suspend may cause problems. Also note there are not interrupts when the 32k sync timer wraps, so something else has to be done.

| | * | | | OMAP3: PM: Force write last pad config register into save areaTero Kristo2010-01-20

Fixed by writing the last register to the save area. Also, optimized the delay loop for the HW save to include an udelay(1), which limits the number of unnecessary HW accesses to SCM register area during the save.
