2009-12-10powerpc/83xx/suspend: Clear deep_sleeping after devices resumeAnton Vorontsov
Currently 83xx PMC driver clears deep_sleeping variable very early, before devices are resumed. This makes fsl_deep_sleep() unusable in drivers' resume() callback. Sure, drivers can store fsl_deep_sleep() value on suspend and use the stored value on resume. But a better solution is to postpone clearing the deep_sleeping variable, i.e. move it into finish() callback.

2009-12-09powerpc/fsl_pci: Fix P2P bridge handling for MPC83xx PCIe controllersAnton Vorontsov
It appears that we wrongly calculate dev_base for type1 config cycles. The thing is: we shouldn't subtract hose->first_busno because PCI core sets PCI primary, secondary and subordinate bus numbers, and PCIe controller actually takes the registers into account. So we should use just bus->number. Also, according to MPC8315 reference manual, primary bus number should always remain 0. We have PPC_INDIRECT_TYPE_SURPRESS_PRIMARY_BUS quirk in indirect_pci.c, but since 83xx is somewhat special, it doesn't use indirect_pci.c routines, so we have to implement the quirk specifically for 83xx PCIe controllers.

e821ea70f3b4873b50056a1e0f74befed1014c09 introduced a bug by copying some 64-bit originated code as-is to be used by both 32 and 64-bit but this code contains a 64-bit ony "cmpdi" instruction. This changes it to cmpwi, which is fine since VRSAVE can only contains a 32-bit value anyway. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: <stable@kernel.org>

2009-12-09powerpc/pseries: Track previous CPPR values to correctly EOI interruptsMark Nelson
At the moment when we EOI an interrupt we set the CPPR back to 0xFF regardless of its previous value. This could lead to problems if we take an interrupt with a priority of 5, but before EOIing it we get an IPI which has a priority of 4. The problem is that at the moment when we EOI the IPI we will set the CPPR to 0xFF, but it should really be set back to 5 (the previous priority). To keep track of the previous CPPR values we create the xics_cppr structure that has an array for CPPR values and an index pointing to the current priority. This can easily grow if new priorities get added in the future. This will also be useful because the partition adjunct option of upcoming machines will update the H_XIRR hcall to accept the CPPR as a parameter.

2009-12-09powerpc/pseries: Correct pseries/dlpar.c build break without CONFIG_SMPNathan Fontenot
The recent patch to add cpu offline/online as part of the DLPAR process for pseries causes a build break if CONFIG_SMP is not defined. Original patch here; http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-November/078299.html This corrects the build break by moving the online_node_cpus and offline_node_cpus under the #ifdef CONFIG_ARCH_CPU_PROBE_RELEASE portions of dlpar.c. This patch also slightly modifies the online_node_cpus and offline_node_cpus routines to prepend dlpar_ to the them and make them static. These two routine are only used in the dlpar add/remove of cpus and these changes should help clarify that.

Writing a driver using SCLPC on the MPC5200B I detected, that the intspec arrays to map irqs to Linux virq cannot be const, because the mapping and xlate functions only take non const pointers.

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.
