Update the TLB asm to make proper use of _PAGE_DIRY and _PAGE_ACCESSED. Get rid of _PAGE_HWWRITE too. Pros: - I/D TLB Miss never needs to write to the linux pte. - _PAGE_ACCESSED is only set on TLB Error fixing accounting - _PAGE_DIRTY is mapped to 0x100, the changed bit, and is set directly when a page has been made dirty. - Proper RO/RW mapping of user space. - Free up 2 SW TLB bits in the linux pte(add back _PAGE_WRITETHRU ?) - kernel RO/user NA support. Cons: - A few more instructions in the TLB Miss routines. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2009-12-09sysfs/cpu: Add probe/release filesNathan Fontenot
Version 3 of this patch is updated with documentation added to Documentation/ABI. There are no changes to any of the C code from v2 of the patch. In order to support kernel DLPAR of CPU resources we need to provide an interface to add (probe) and remove (release) the resource from the system. This patch Creates new generic probe and release sysfs files to facilitate cpu probe/release. The probe/release interface provides for allowing each arch to supply their own routines for implementing the backend of adding and removing cpus to/from the system. This also creates the powerpc specific stubs to handle the arch callouts from writes to the sysfs files. The creation and use of these files is regulated by the CONFIG_ARCH_CPU_PROBE_RELEASE option so that only architectures that need the capability will have the files created.

2009-12-09powerpc/pseries: Kernel DLPAR InfrastructureNathan Fontenot
The Dynamic Logical Partitioning capabilities of the powerpc pseries platform allows for the addition and removal of resources (i.e. CPU's, memory, and PCI devices) from a partition. The removal of a resource involves removing the resource's node from the device tree and then returning the resource to firmware via the rtas set-indicator call. To add a resource, it is first obtained from firmware via the rtas set-indicator call and then a new device tree node is created using the ibm,configure-coinnector rtas call and added to the device tree. This patch provides the kernel DLPAR infrastructure in a new filed named dlpar.c. The functionality provided is for acquiring and releasing a resource from firmware and the parsing of information returned from the ibm,configure-connector rtas call. Additionally this exports the pSeries reconfiguration notifier chain so that it can be invoked when device tree updates are made.

2009-12-09powerpc/macio: Rework hotplug media bay supportBenjamin Herrenschmidt
The hotplug mediabay has tendrils deep into drivers/ide code which makes a libata port reather difficult. In addition it's ugly and could be done better. This reworks the interface between the mediabay and the rest of the world so that: - Any macio_driver can now have a mediabay_event callback which will be called when that driver sits on a mediabay and it's been either plugged or unplugged. The device type is passed as an argument. We can now move all the IDE cruft into the IDE driver itself - A check_media_bay() function can be used to take a peek at the type of device currently in the bay if any, a cleaner variant of the previous function with the same name. - A pair of lock/unlock functions are exposed to allow the IDE driver to block the hotplug callbacks during the initial setup and probing of the bay in order to avoid nasty race conditions. - The mediabay code no longer needs to spin on the status register of the IDE interface when it detects an IDE device, this is done just fine by the IDE code itself Overall, less code, simpler, and allows for another driver than our old drivers/ide based one.

2009-12-08powerpc/mm: Fix pgtable cache cleanup with CONFIG_PPC_SUBPAGE_PROTDavid Gibson
Commit a0668cdc154e54bf0c85182e0535eea237d53146 cleans up the handling of kmem_caches for allocating various levels of pagetables. Unfortunately, it conflicts badly with CONFIG_PPC_SUBPAGE_PROT, due to the latter's cleverly hidden technique of adding some extra allocation space to the top level page directory to store the extra information it needs. Since that extra allocation really doesn't fit into the cleaned up page directory allocating scheme, this patch alters CONFIG_PPC_SUBPAGE_PROT to instead allocate its struct subpage_prot_table as part of the mm_context_t.

CONFIG_PPC_SUBPAGE_PROT" This reverts commit c045256d146800ea1d741a8e9e377dada6b7e195. It breaks build when CONFIG_PPC_SUBPAGE_PROT is not set. I will commit a fixed version separately Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-12-01powerpc: Fix DEBUG_HIGHMEM build break from d4515646699Becky Bruce
Code was added to mm/higmem.c that depends on several kmap types that powerpc does not support. We add dummy invalid definitions for KM_NMI, KM_NM_PTE, and KM_IRQ_PTE. According to list discussion, this fix should not be needed anymore starting with 2.6.33. The code is commented to this effect so hopefully we will remember to remove this.

2009-11-27powerpc/mm: Fix bug in pagetable cache cleanup with CONFIG_PPC_SUBPAGE_PROTDavid Gibson
Commit a0668cdc154e54bf0c85182e0535eea237d53146 cleans up the handling of kmem_caches for allocating various levels of pagetables. Unfortunately, it conflicts badly with CONFIG_PPC_SUBPAGE_PROT, due to the latter's cleverly hidden technique of adding some extra allocation space to the top level page directory to store the extra information it needs. Since that extra allocation really doesn't fit into the cleaned up page directory allocating scheme, this patch alters CONFIG_PPC_SUBPAGE_PROT to instead allocate its struct subpage_prot_table as part of the mm_context_t.

2009-11-26block: add helpers to run flush_dcache_page() against a bio and a request's ↵Ilya Loginov
pages Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information.
