| * powerpc/eeh: Don't panic when EEH_MAX_FAILS is exceededMike Mason2008-07-221-14/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * powerpc/cell: Add DMA_ATTR_WEAK_ORDERING dma attribute and use in Cell IOMMU ↵Mark Nelson2008-07-221-5/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This is currently decided by a kernel boot option (pass iommu_fixed=weak for a weakly ordered fixed linear mapping, strongly ordered is the default).

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the power button on future IBM cell blades. It actually doesn't shut down the machine. Instead it exposes an input device /dev/input/event0 to userspace which sends KEY_POWER if power button has been pressed. haldaemon actually recognizes the button, so a plattform independent acpid replacement should handle it correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a cpufreq governor that takes the number of running spus into account. It's very similar to the ondemand governor, but not as complex. Instead of hacking spu load into the ondemand governor it might be easier to have cpufreq accepting multiple governors per cpu in future. Don't know if this is the right way, but it would keep the governors simple.

| * Revert "powerpc/ep8248e: Fix compile problem if !CONFIG_FS_ENET"Kumar Gala2008-07-161-4/+0
| | | | | | | | | | | | | | This reverts commit e3621ee633810be1079d0fa65ac2c904f53b73fa. This was not the proper fix. As Scott Wood said CONFIG_FS_ENET has nothing to do with the issue. The proper fix is to select PHYLIB for this board.
| * powerpc/ep8248e: Unconditionally select PHYLIB for mdio_bitbangKumar Gala2008-07-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Its possible to build the phylib as a module, however this breaks the board code because alloc_mdio_bitbang and mdiobus_register are not available if we build as a module. These are needed by the board code since it implements the low level mdio bitbang ops. So we unconditionally select PHYLIB to ensure its built into the kernel if we are building in EP8248E support. Long term we should look at moving the mdio_ops into its own file so it can be built as a module. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| * powerpc/85xx/86xx: some refactoring for fsl_uli1575 codeAnton Vorontsov2008-07-165-99/+108
| | | | | | | | | | | | | | | | | | | | | | | | - Get rid of uses_fsl_uli_m1575, it does not scale for all cases. Instead, let's explicitly use machine_is() for each fixup. - Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with machine_is(). One step closer to multiplatform kernels. - Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied. - RTC quirk applies to all boards though, so no machine_is() checks.

| * powerpc/fsl_uli1575: fix RTC quirk to work on MPC8572DS and MPC8610HPCDAnton Vorontsov2008-07-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes RTC on MPC8572DS boards: dummy read helps only when reading at the end of the bridge's memory (i.e. outside of behind the bridge devices' assigned regions). With this change the quirk also makes RTC work on MPC8610HPCD, so it's unlikely that this will break MPC8641HPCN or MPC8544DS boards.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Choosing PCI or not at config time is allowed on some platforms via an if expression in arch/powerpc/Kconfig. To add a new platform with PCI support selectable at config time, you must change the if expression. This patch makes this easier by changing: bool "PCI support" if <long expression> to bool "PCI support" if PPC_PCI_CHOICE and adding select PPC_PCI_CHOICE to all the config nodes that were previously in the PCI if expression. Platforms with unconditional PCI support continue to just select PCI in their config nodes.

* | sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen2008-07-212-16/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This patch fixes this so suspend/resume works: 1) of_iomap does not map the whole 0xC000 of the MPC5200 immr so saving registers does not work. 2) PCI registers need to be saved and restored.

* | | | | | powerpc/eeh: PERR/SERR bit settings during EEH device recoveryMike Mason2008-07-091-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch restores the PERR and SERR bits in the PCI command register during an EEH device recovery. We have found at least one case (an Agilent test card) where the PERR/SERR bits are set to 1 by firmware at boot time, but are not restored to 1 during EEH recovery. The patch fixes the Agilent card problem. It has been tested on several other EEH-enabled cards with no regressions.
