* mm: move bootmem descriptors definition to a single placeJohannes Weiner2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | There are a lot of places that define either a single bootmem descriptor or an array of them. Use only one central array with MAX_NUMNODES items instead.

* add HAVE_CLK to Kconfig, for driver dependenciesDavid Brownell2008-07-24
| | | | | | | | | | | | | | | | | | | | Flag platforms as HAVE_CLK (or not) in Kconfig, based on whether they support <linux/clk.h> calls, so that otherwise portable drivers which need those calls can list that dependency. Something like this is a prerequisite for merging the musb_hdrc driver, currently used on platforms including Davinci, OMAP2430, OMAP3xx ... and the discrete TUSB6010 chip, which doesn't have a natural platform dependency. (Used with OMAP 2420 in current Nokia N8x0 tablets.)

* kgdb, powerpc: arch specific powerpc kgdb supportJason Wessel2008-07-23
| | | | | | | | | | | | | | | | | This patch removes the old kgdb reminants from ARCH=powerpc and implements the new style arch specific stub for the common kgdb core interface. It is possible to have xmon and kgdb in the same kernel, but you cannot use both at the same time because there is only one set of debug hooks. The arch specific kgdb implementation saves the previous state of the debug hooks and restores them if you unconfigure the kgdb I/O driver. Kgdb should have no impact on a kernel that has no kgdb I/O driver configured. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>

| * | powerpc: Fix build bug with binutils < 2.18 and GCC < 4.2Segher Boessenkool2008-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | binutils < 2.18 has a bug that makes it misbehave when taking an ELF file with all segments at load address 0 as input. This happens when running "strip" on vmlinux, because of the AT() magic in this linker script. People using GCC >= 4.2 won't run into this problem, because the "build-id" support will put some data into the "notes" segment (at a non-zero load address). To work around this, we force some data into both the "dummy" segment and the kernel segment, so the dummy segment will get a non-zero load address. It's not enough to always create the "notes" segment, since if nothing gets assigned to it, its load address will be zero.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the EEH_MAX_FAILS action from panic to printing an error message. Panicking under under this condition is too harsh. Although performance will be affected and the device may not recover, the system is still running, which at the very least should allow for a more graceful shutdown. The patch also removes the msleep() within a spinlock, which can lead to a deadlock and is not recommended.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | code Introduce a new dma attriblue DMA_ATTR_WEAK_ORDERING to use weak ordering on DMA mappings in the Cell processor. Add the code to the Cell's IOMMU implementation to use this code. Dynamic mappings can be weakly or strongly ordered on an individual basis but the fixed mapping has to be either completely strong or completely weak.

Once the default case is selected, non of the oprofile counters and/or fields have been set up or defined. When identify_cpu() is called once more with the logical PVR, some of the cpu specific fields are replaced with the exception of the oprofile related ones. However, in the case where we have actually taken the default case while searching for the real PVR, we need to tell oprofile that we are now running in compatibility mode so it can pick up the correct counters. We do this by setting the oprofile_cpu_type field to be that taken from the cpu_specs[] for the cpu we are now emulating. This change will detect that we are now altering the real PVR and determine if we also need to update the oprofile_cpu_type field.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Basic PM support for 83xx. Standby is implemented as sleep. Suspend-to-RAM is implemented as "deep sleep" (with the processor turned off) on 831x. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* | | sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen2008-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections. Runtime tested: x86-32, x86-64 Compiled only: ia64, powerpc Not compile tested/only grep converted: sh, arm, avr32 Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
