Add spi support for mgcoge into the platform code and the dts file. Additionaly SPIDEV is switched on in the defconfig and the updates for the newer kernel version are committed. The SPI interface is used to drive the Maxim DS3106 clock chip. Signed-off-by:

Fix RGMII workaround code in km83xx.c for MPC8360E and MPC8358E that it correctly identifes all affected SoC chip models and applies the workarounds appropriate for 2.0 and 2.1 revisions as per Freescale MPC8360ECE Errata document Rev.5(9/2011) item QE_ENET10. Signed-off-by:

Change quirk_fsl_pcie_header from __init to __devinit to ensure if we have a runtime access (like via an FPGA being loaded after boot on the PCIe link) that we dont access randomly freed memory. Signed-off-by:

Matt added BPF_JIT support in commit 0ca87f05, but currently none of our defconfigs build it. Turn that sucker on. Signed-off-by:

Add the ability to inject IOMMU faults. We enable this per device via a fail_iommu sysfs property, similar to fault injection on other subsystems. An example: ... 0003:01:00.1 Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 02) To inject one error to this device: echo 1 > /sys/bus/pci/devices/0003:01:00.1/fail_iommu echo 1 > /sys/kernel/debug/fail_iommu/probability echo 1 > /sys/kernel/debug/fail_iommu/times As feared, the first failure injected on the be3 results in an unrecoverable error, taking down both functions of the card permanently: be2net 0003:01:00.1: Unrecoverable error in the card Signed-off-by:

The DMA API debug code has hooks to verify all DMA entries have been freed at time of hot unplug. We need to call dma_debug_add_bus for this to work. Signed-off-by:

Similar to PCI, separate the bus probe from device probe. This allows us to attach bus notifiers for DMA debug and IOMMU fault injection before devices have been probed. Signed-off-by:

Anton Blanchard authored
During boot we see a number of these warnings: vio 30000000: Warning: IOMMU dma not supported: mask 0xffffffffffffffff, table unavailable The reason for this is that we set IOMMU properties for all VIO devices even if they are not DMA capable. Only set DMA ops, table and mask for devices with a DMA window. Signed-off-by:

We use SIAR or regs->nip for the instruction pointer depending on the PMU configuration, but we always use regs->nip in the callchain. Use perf_instruction_pointer so the backtrace is consistent. Signed-off-by:
-
Anton Blanchard authored
At the moment we always use the SIAR if the PMU supports continuous sampling. Unfortunately the SIAR and the PMU exception are not synchronised for non marked events so we can end up with callchains that dont make sense. The following patch checks the HV and PR bits for samples coming from userspace and always uses pt_regs for them. Userspace will never have interrupts off so there is no real advantage to using the SIAR for non marked events in userspace. I had experimented with a patch that did a similar thing for kernel samples but we lost a significant amount of information. I was unable to profile any of our early exception code for example.

Anton Blanchard authored
The logic to choose whether to use the SIAR or get the information out of pt_regs is going to get more complicated, so do it once in perf_read_regs. We overload regs->result which is gross but we are already doing it with regs->dsisr. Signed-off-by:

We want to access the MMCRA_SIHV and MMCRA_SIPR bits elsewhere so create mmcra_sihv and mmcra_sipr which hide the differences between the old and new layout of the bits. Signed-off-by:

Some macros use RA where when RA=R0 the values is 0, so make this the enforced mnemonic in the macro. Idea suggested by Andreas Schwab. Signed-off-by:

Enforce the use of R0-R31 in macros where possible now we have all the fixes in. R0-R31 macros are removed here so that can't be used anymore. They should not be defined anywhere. Signed-off-by:

Now have ___PPC_RA/B/S/T we can use it in some places. These are places where we can't use the existing defines which will soon enforce R0-R31 usage. The macros being changed here are being used in inline asm, which can't convert to enforce the R0-R31 usage. bpf_jit uses a mix of both generated and non-generated with the same code, so just convert all these to use the ___PPC_R versions which won't enforce R usage later.

These are currently the same as __PPC_RA/B/S/T but we'll wrap them soon. Signed-off-by:

We need to do this so we can enforce the name of a and b in called macros PPC_RA/B later. Signed-off-by:

These macros are using integers where they could be using logical names since they take registers. We are going to enforce this soon, so fix these up now. Signed-off-by:

LOAD_REG_ADDR define is just a wrapper around real instructions so we can just use real register names here (ie. lower case). Signed-off-by:

Anything that uses a constructed instruction (ie. from ppc-opcode.h), need to use the new R0 macro, as %r0 is not going to work. Also convert usages of macros where we are just determining an offset (usually for a load/store), like: std r14,STK_REG(r14)(r1) Can't use STK_REG(r14) as %r14 doesn't work in the STK_REG macro since it's just calculating an offset.

Newer gcc are being a bit blind here (it's pretty obvious we don't reach the code path using the array if we haven't initialized the pointer) but none of that is performance critical so let's just silence it. Signed-off-by: -

There was a typo, checking for CONFIG_TRACE_IRQFLAG instead of CONFIG_TRACE_IRQFLAGS causing some useful debug code to not be built This in turns causes a build error on BookE 64-bit due to incorrect semicolons at the end of a couple of macros, so let's fix that too Signed-off-by:
