Richard Henderson pointed out that the powerpc __futex_atomic_op has a bug: it will write the wrong value if the stwcx. fails and it has to retry the lwarx/stwcx. loop, since 'oparg' will have been overwritten by the result from the first time around the loop. This happens because it uses the same register for 'oparg' (an input) as it uses for the result. This fixes it by using separate registers for 'oparg' and 'ret'.

While adding native EEH support to Emulex and Qlogic drivers, it was discovered that dev->error_state was set to pci_io_channel_normal too late in the recovery process. These drivers rely on error_state to determine if they can access the device in their slot_reset callback, thus error_state needs to be set to pci_io_channel_normal in eeh_report_reset(). Below is a detailed explanation (courtesy of Richard Lary) as to why this is necessary. Background: PCI MMIO or DMA accesses to a frozen slot generate additional EEH errors. If the number of additional EEH errors exceeds EEH_MAX_FAILS the adapter will be shutdown. To avoid triggering excessive EEH errors and an undesirable adapter shutdown, some drivers use the pci_channel_offline(dev) wrapper function to return a Boolean value based on the value of pci_dev->error_state to determine if PCI MMIO or DMA accesses are safe. If the wrapper returns TRUE, drivers must not make PCI MMIO or DMA access to their hardware. The pci_dev structure member error_state reflects one of three values, 1) pci_channel_io_normal, 2) pci_channel_io_frozen, 3) pci_channel_io_perm_failure. Function pci_channel_offline(dev) returns TRUE if error_state is pci_channel_io_frozen or pci_channel_io_perm_failure. The EEH driver sets pci_dev->error_state to pci_channel_io_frozen at the point where the PCI slot is frozen. Currently, the EEH driver restores dev->error_state to pci_channel_io_normal in eeh_report_resume() before calling the driver's resume callback. However, when the EEH driver calls the driver's slot_reset callback() from eeh_report_reset(), it incorrectly indicates the error state is still pci_channel_io_frozen. Waiting until eeh_report_resume() to restore dev->error_state to pci_channel_io_normal is too late for Emulex and QLogic FC drivers and any other drivers which are designed to use common code paths in these two cases: i) those called after the driver's slot_reset callback() and ii) those called after the PCI slot is frozen but before the driver's slot_reset callback is called. Case i) all driver paths executed to reinitialize the hardware after a reset and case ii) all code paths executed by driver kernel threads that run asynchronous to the main driver thread, such as interrupt handlers and worker threads to process driver work queues. Emulex and QLogic FC drivers are designed with common code paths which require that pci_channel_offline(dev) reflect the true state of the hardware. The state transitions that the hardware takes from Normal Operations to Slot Frozen to Reset to Normal Operations are documented in the Power Architecture™ Platform Requirements+ (PAPR+) in Table 75. PE State Control. PAPR defines the following 3 states: 0 -- Not reset, Not EEH stopped, MMIO load/store allowed, DMA allowed (Normal Operations) 1 -- Reset, Not EEH stopped, MMIO load/store disabled, DMA disabled 2 -- Not reset, EEH stopped, MMIO load/store disabled, DMA disabled (Slot Frozen) An EEH error places the slot in state 2 (Frozen) and the adapter driver is notified that an EEH error was detected. If the adapter driver returns PCI_ERS_RESULT_NEED_RESET, the EEH driver calls eeh_reset_device() to place the slot into state 1 (Reset) and eeh_reset_device completes by placing the slot into State 0 (Normal Operations). Upon return from eeh_reset_device(), the EEH driver calls eeh_report_reset, which then calls the adapter's slot_reset callback. At the time the adapter's slot_reset callback is called, the true state of the hardware is Normal Operations and should be accurately reflected by setting dev->error_state to pci_channel_io_normal. The current implementation of EEH driver does not do so and requires this change to correct this deficiency.

This fixes a problem reported by Sean MacLennan where loading any module would cause an oops. We weren't marking the pages containing the module text as having hardware execute permission, due to a bug introduced in commit 8d1cf34e ("powerpc/mm: Tweak PTE bit combination definitions"), hence trying to execute the module text caused an exception on processors that support hardware execute permission. This adds _PAGE_HWEXEC to the definitions of PAGE_KERNEL_X and PAGE_KERNEL_ROX to fix this problem.

The ptrace compat wrapper mishandles access to the fpu registers. The PTRACE_PEEKUSR and PTRACE_POKEUSR requests miscalculate the index into the fpr array due to the broken FPINDEX macro. The PPC_PTRACE_PEEKUSR_3264 request needs to use the same formula that the native ptrace interface uses when operating on the register number (as opposed to the 4-byte offset).

When we call giveup_fpu, we need to need to turn off VSX for the current process. If we don't, on return to userspace it may execute a VSX instruction before the next FP instruction, and not have its register state refreshed correctly from the thread_struct. Ditto for altivec. This caused a bug where an unaligned lfs or stfs results in fix_alignment calling giveup_fpu so it can use the FPRs (in order to do a single <-> double conversion), and then returning to userspace with FP off but VSX on. Then if a VSX instruction is executed, before another FP instruction, it will proceed without another exception and hence have the incorrect register state for VSX registers 0-31. lfs unaligned <- alignment exception turns FP off but leaves VSX on VSX instruction <- no exception since VSX on, hence we get the wrong VSX register values for VSX registers 0-31, which overlap the FPRs.

The (relatively) new pmac_zilog driver doesn't use the pre-munged IRQ numbers from the macio_dev unlike other macio things, it directly maps it off the OF device-tree. It does that because it can be initialized much earlier than the registration of the macio devices, in order to get a serial console early. Unfortunately, that means that it "misses" some fixups done by the macio layer to work around missing interrupt descriptions in the device-tree of the Wallstreet machines. This patch brings the necessary workaround into the pmac_zilog driver itself to bring it back to working condition.
