* [POWERPC] Use mtocrf instruction in asm when CONFIG_POWER4_ONLY=yOlof Johansson2007-04-131-0/+10
| | | | | | | | | | mtocrf is a faster single-field mtcrf (move to condition register fields) instruction available in POWER4 and later processors. It can make quite a difference in performance on some implementations, so use it for CONFIG_POWER4_ONLY builds.

* [POWERPC] Add a unified uevent handler for bus based on of_deviceSylvain Munaut2007-04-131-0/+3
| | | | | | | | | | | | | This common uevent handler allow the several bus types based on of_device to generate the uevent properly and avoiding code duplication. This handlers take a struct device as argument and can therefore be used as the uevent call directly if no special treatment is needed for the bus.

| * [POWERPC] Avoid hypervisor statistics calculation in real modeMohan Kumar M2007-03-221-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | kexec invokes plpar_hcall hypervisor call in real mode. plpar_hcall refers to per cpu variables for accounting hypervisor statistics. These variables may not be in the RMO region, so accesses to them in real mode may result in a data storage exception. This fixes this problem by using a new plpar_hcall_raw function which does not update the hypervisor call statistics. Thanks to Anton for suggesting this idea.

| * [POWERPC] Fix spu SLB invalidationsBenjamin Herrenschmidt2007-03-102-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPU code doesn't properly invalidate SPUs SLBs when necessary, for example when changing a segment size from the hugetlbfs code. In addition, it saves and restores the SLB content on context switches which makes it harder to properly handle those invalidations. This patch removes the saving & restoring for now, something more efficient might be found later on. It also adds a spu_flush_all_slbs(mm) that can be used by the core mm code to flush the SLBs of all SPEs that are running a given mm at the time of the flush. In order to do that, it adds a spinlock to the list of all SPEs and move some bits & pieces from spufs to spu_base.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* | [POWERPC] Update documentation for flat device tree format v17David Gibson2007-03-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates booting-without-of.txt to describe version 17 of the flattened device tree format. Version 17 is a small, backwards compatible change from version 16, adding an extra field giving the size of the device tree's structure block. At this time, the kernel has no use for the extra information, however its presence can make life easier for bootloaders or other software manipulating the tree. In addition this patch adds information on the size_dt_strings field of the device tree header, present since version 3 of the flattened tree format, but omitted from the documentation. It also makes changes to consistently refer to versions 16 and 17 as versions 16 and 17 in decimal, rather than version 0x10 which was occasionally used for version 16 previously. Finally, we also add the new field to the definition of the device tree header structure in prom.h Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Jon Loeliger <jdl@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* | [POWERPC] ibmebus: dynamic addition/removal of adapters, some code cleanupJoachim Fenkes2007-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds two sysfs attributes to /sys/bus/ibmebus which can be used to notify the ebus driver of added / removed ebus devices in the OF device tree. Echoing the device's location code (as found in the OFDT "ibm,loc-code" property) into the "probe" attribute will notify ebus of addition of the device and cause the appropriate device driver's probe function to be called on the device. Likewise, echoing the location code into the "remove" attribute will cause the device to be removed from the system. The writes will block until the respective operation has finished and return an error code if the operation failed. In addition, two minor tidbits are fixed: - The fake root device used to provide a common parent for all ebus devices is now based on device instead of of_device - it had no associated devtree node. This saves several checks throughout the ebus driver. - The sysfs attributes are now generated automagically by device_register() instead of by the ibmebus code, which saves a few compiler warnings about unused return codes.

* [PATCH] sched: remove SMT niceCon Kolivas2007-03-051-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove the SMT-nice feature which idles sibling cpus on SMT cpus to facilitiate nice working properly where cpu power is shared. The idling of cpus in the presence of runnable tasks is considered too fragile, easy to break with outside code, and the complexity of managing this system if an architecture comes along with many logical cores sharing cpu power will be unworkable. Remove the associated per_cpu_gain variable in sched_domains used only by this code. Also: The reason is that with dynticks enabled, this code breaks without yet further tweaks so dynticks brought on the rapid demise of this code. So either we tweak this code or kill it off entirely. It was Ingo's preference to kill it off. Either way this needs to happen for 2.6.21 since dynticks has gone in.

| | | | | | | | | | | | | | | | | Getting BenH's new EMAC driver working on 440GP, I found some more problems in the native mode paths of the new DCR code: - dcr_map() is supposed to return a dcr_host_t, but the native version is a macro that doesn't expand to an expression. With native DCRs, dcr_host_t is an empty structure, so we just use a constructor expression instead. - dcr_unmap() uses {} instead of the safer do {} while (0) idiom to implement a no-op Here's a fix.

* | [PATCH] consolidate line discipline number definitionsTilman Schmidt2007-02-111-18/+0
|/ | | | | | | | | | | | | | | | | | | The line discipline numbers N_* are currently defined for each architecture individually, but (except for a seeming mistake) identically, in asm/termios.h. There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet.
