| * | powerpc/ps3: Fix ioremap of spu shadow regsMasakazu Mokuno2008-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the ioremap of the spu shadow regs on the PS3. The current PS3 hypervisor requires the spu shadow regs to be mapped with the PTE page protection bits set as read-only (PP=3). This implementation uses the low level __ioremap() to bypass the page protection settings inforced by ioremap_flags() to get the needed PTE bits set for the shadow regs. This fixes a runtime failure on the PS3 introduced by the powerpc ioremap_prot rework of commit a1f242ff460e4b50a045fa237c3c56cce9eabf83 ("powerpc ioremap_prot").

| * powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devicesJoachim Fenkes2008-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on an original patch from Christoph Hellwig <hch@lst.de>. Currently, there is a possible reference-after-free in the spusched code - contexts may be freed after we have released their state_mutex in spusched_tick and find_victim. This change takes a reference to the context before releasing the mutex, so that the context doesn't get destroyed. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
| | * powerpc/spufs: fix npc setting for NOSCHED contextsJeremy Kerr2008-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, spu_run ignores the npc argument for contexts created with SPU_CREATE_NOSCHED. While this is correct for isolated contexts, there's no need to enforce the npc restriction on non-isolated NOSCHED contexts. This means that NOSCHED contexts can only ever run with an entry point of 0x0. This change to spu_run_init allows setting of the npc (and, while we're at it, the privcntl) for non-isolated NOSCHED contexts. This allows us to run NOSCHED contexts from any entry point.

A loop counter is set up at the high value and decremented by page size. However, the loop is only done once as the sense of the conditional branch at the loop end does not match the setup/decrement.

| * | powerpc/mm: Fix attribute confusion with htab_bolt_mapping()Benjamin Herrenschmidt2008-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function htab_bolt_mapping() is used to create permanent mappings in the MMU hash table, for example, in order to create the linear mapping of vmemmap. It's also used by early boot ioremap (before mem_init_done). However, the way ioremap uses it is incorrect as it passes it the protection flags in the "linux PTE" form while htab_bolt_mapping() expects them in the hash table format. This is made more confusing by the fact that some of those flags are actually in the same position in both cases. This fixes it all by making htab_bolt_mapping() take normal linux protection flags instead, and use a little helper to convert them to htab flags. Callers can now use the usual PAGE_* definitions safely.

| * | powerpc/pci: Don't keep ISA memory hole resources in the treeBenjamin Herrenschmidt2008-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have an ISA memory hole (ie, a PCI window that allows us to generate PCI memory cycles at low PCI address) mixed with other resources using a different CPU <=> PCI mapping, we must not keep the ISA hole in the bridge resource list. If we do, things might start trying to allocate device resources in there and will get the PCI addresses wrong. This fixes it by arranging to remove the ISA memory hole resource in this case. This fixes various cases of PCMCIA breakage on PowerBooks using the MPC106 "grackle" bridge.

| * | powerpc: Zero fill the return values of rtas argument bufferNathan Fontenot2008-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel copy of the rtas args struct contains the return value(s) for the specified rtas call. These are copied back to user space with the assumption that every value has been set by the rtas call, which turns out to be not always true. Thus userspace can see random values and think the call failed when in fact it succeeded, but for some reason didn't set one of the return values. This fixes the problem by zeroing out the return value fields of the rtas args struct before processing the rtas call.
