2009-01-07USB: powerpc: Workaround for the PPC440EPX USBH_23 errata [take 3]Vitaly Bordug
A published errata for ppc440epx states, that when running Linux with both EHCI and OHCI modules loaded, the EHCI module experiences a fatal error when a high-speed device is connected to the USB2.0, and functions normally if OHCI module is not loaded. There used to be recommendation to use only hi-speed or full-speed devices with specific conditions, when respective module was unloaded. Later, it was observed that ohci suspend is enough to keep things going, and it was turned into workaround, as explained below. Quote from original descriprion: The 440EPx USB 2.0 Host controller is an EHCI compliant controller. In USB 2.0 Host controllers, each EHCI controller has one or more companion controllers, which may be OHCI or UHCI. An USB 2.0 Host controller will contain one or more ports. For each port, only one of the controllers is connected at any one time. In the 440EPx, there is only one OHCI companion controller, and only one USB 2.0 Host port. All ports on an USB 2.0 controller default to the companion controller. If you load only an ohci driver, it will have control of the ports and any deviceplugged in will operate, although high speed devices will be forced to operate at full speed. When an ehci driver is loaded, it explicitly takes control of the ports. If there is a device connected, and / or every time there is a new device connected, the ehci driver determines if the device is high speed or not. If it is high speed, the driver retains control of the port. If it is not, the driver explicitly gives the companion controller control of the port. The is a software workaround that uses Initial version of the software workaround was posted to linux-usb-devel: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg54019.html and later available from amcc.com: http://www.amcc.com/Embedded/Downloads/download.html?cat=1&family=15&ins=2 The patch below is generally based on the latter, but reworked to powerpc/of_device USB drivers, and uses a few devicetree inquiries to get rid of (some) hardcoded defines.

2009-01-06remove linux/hardirq.h from asm-generic/local.hRussell King
While looking at reducing the amount of architecture namespace pollution in the generic kernel, I found that asm/irq.h is included in the vast majority of compilations on ARM (around 650 files.) Since asm/irq.h includes a sub-architecture include file on ARM, this causes a negative impact on the ccache's ability to re-use the build results from other sub-architectures, so we have a desire to reduce the dependencies on asm/irq.h. It turns out that a major cause of this is the needless include of linux/hardirq.h into asm-generic/local.h. The patch below removes this include, resulting in some 250 to 300 files (around half) of the kernel then omitting asm/irq.h. My test builds still succeed, provided two ARM files are fixed (arch/arm/kernel/traps.c and arch/arm/mm/fault.c) - so there may be negative impacts for this on other architectures. Note that x86 does not include asm/irq.h nor linux/hardirq.h in its asm/local.h, so this patch can be viewed as bringing the generic version into line with the x86 version.

2009-01-06mm: show node to memory section relationship with symlinks in sysfsGary Hade
Show node to memory section relationship with symlinks in sysfs Add /sys/devices/system/node/nodeX/memoryY symlinks for all the memory sections located on nodeX. For example: /sys/devices/system/node/node1/memory135 -> ../../memory/memory135 indicates that memory section 135 resides on node1. Also revises documentation to cover this change as well as updating Documentation/ABI/testing/sysfs-devices-memory to include descriptions of memory hotremove files 'phys_device', 'phys_index', and 'state' that were previously not described there. In addition to it always being a good policy to provide users with the maximum possible amount of physical location information for resources that can be hot-added and/or hot-removed, the following are some (but likely not all) of the user benefits provided by this change. Immediate: - Provides information needed to determine the specific node on which a defective DIMM is located. This will reduce system downtime when the node or defective DIMM is swapped out. - Prevents unintended onlining of a memory section that was previously offlined due to a defective DIMM. This could happen during node hot-add when the user or node hot-add assist script onlines _all_ offlined sections due to user or script inability to identify the specific memory sections located on the hot-added node. The consequences of reintroducing the defective memory could be ugly. - Provides information needed to vary the amount and distribution of memory on specific nodes for testing or debugging purposes. Future: - Will provide information needed to identify the memory sections that need to be offlined prior to physical removal of a specific node. Symlink creation during boot was tested on 2-node x86_64, 2-node ppc64, and 2-node ia64 systems. Symlink creation during physical memory hot-add tested on a 2-node x86_64 system.

2009-01-06mm: invoke oom-killer from page faultNick Piggin
Rather than have the pagefault handler kill a process directly if it gets a VM_FAULT_OOM, have it call into the OOM killer. With increasingly sophisticated oom behaviour (cpusets, memory cgroups, oom killing throttling, oom priority adjustment or selective disabling, panic on oom, etc), it's silly to unconditionally kill the faulting process at page fault time. Create a hook for pagefault oom path to call into instead. Only converted x86 and uml so far.

2009-01-06mm: report the MMU pagesize in /proc/pid/smapsMel Gorman
The KernelPageSize entry in /proc/pid/smaps is the pagesize used by the kernel to back a VMA. This matches the size used by the MMU in the majority of cases. However, one counter-example occurs on PPC64 kernels whereby a kernel using 64K as a base pagesize may still use 4K pages for the MMU on older processor. To distinguish, this patch reports MMUPageSize as the pagesize used by the MMU in /proc/pid/smaps.

2009-01-05get rid of the last symlink in uml buildAl Viro
We need to make asm-offsets.h contents visible for objects built with userland headers. Instead of creating a symlink, just have the file with equivalent include (relative to location of header) created once. That kills the last symlink used in arch/um builds. Additionally, both generated headers can become dependencies of archprepare now, killing the misuse of prepare.

... and don't bother in callers. Don't bother with zeroing i_blocks, while we are at it - it's already been zeroed. i_mode is not worth the effort; it has no common default value. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2009-01-05sparc: Clean arch-specific code in prom_common.cJulian Calaby
prom_nextprop() and prom_firstprop() have slightly different calling conventions in 32 and 64 bit SPARC. prom_common.c uses a ifdef guard to ensure that these functions are called correctly. Adjust code to eliminate this ifdef by using a calling convention that is compatible with both 32 and 64 bit SPARC.

2009-01-04sparc: Kill asm/reg*.hDavid S. Miller
As noticed by Sam Ravnborg, these aren't use for anything. Neither the kernel nor userland make a reference to this family of header files. So just get rid of them. Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-04sparc: Use 64BIT config entryBastian Blank
Use 64BIT config entry to distinguish between 32 and 64bit builds instead of relying on the ARCH setting. Using sparc64 as ARCH still forces 64BIT on. Inspired by the x86 and s390 configs.
