      powerpc/ppc64: Gracefully handle early interrupts · a944a9c4
      Benjamin Herrenschmidt authored
      If we take an interrupt such as a trap caused by a BUG_ON before the
      MMU has been setup, the interrupt handlers try to enable virutal mode
      and cause a recursive crash, making the original problem very hard
      to debug.
      
      This fixes it by adjusting the "kernel_msr" value in the PACA so that
      it only has MSR_IR and MSR_DR (translation for instruction and data)
      set after the MMU has been initialized for the processor.
      
      We may still not have a console yet but at least we don't get into
      a recursive fault (and early debug console or memory dump via JTAG
      of the kernel buffer *will* give us the proper error).

      powerpc/prom: early_init_dt_scan_cpus() updates cpu features only once · 7222f779
      Benjamin Herrenschmidt authored
      All our cpu feature updates were done for every CPU in the device-tree,
      thus overwriting the cputable bits over and over again. Instead do them
      only for the boot CPU.

      Move the definition to setup-common.c and set the init value
      to -1 on both 32 and 64-bit (it was 0 on 64-bit).
      
      Additionally add a check to prom.c to garantee that the init
      value has been udpated after the DT scan.

      powerpc/tm: Disable IRQ in tm_recheckpoint · e6b8fd02
      Michael Neuling authored
      We can't take an IRQ when we're about to do a trechkpt as our GPR state is set
      to user GPR values.
      
      We've hit this when running some IBM Java stress tests in the lab resulting in
      the following dump:

      This moves tm_recheckpoint to a C function and moves the tm_restore_sprs into
      that function.  It then adds IRQ disabling over the trechkpt critical section.
      It also sets the TEXASR FS in the signals code to ensure this is never set now
      that we explictly write the TM sprs in tm_recheckpoint.

      powerpc/le: Enable RTAS events support · a08a53ea
      Greg Kurz authored
      The current kernel code assumes big endian and parses RTAS events all
      wrong. The most visible effect is that we cannot honor EPOW events,
      meaning, for example, we cannot shut down a guest properly from the
      hypervisor.
      
      This new patch is largely inspired by Nathan's work: we get rid of all
      the bit fields in the RTAS event structures (even the unused ones, for
      consistency). We also introduce endian safe accessors for the fields used
      by the kernel (trivial rtas_error_type() accessor added for consistency).

      powerpc: Correct emulated mtfsf instruction · c59c015b
      Stephen Chivers authored
      The emulated (CONFIG_MATH_EMULATION_FULL)
      PowerPC Floating Point instruction mtfsf
      does not correctly copy bits from its source
      register to the Floating Point Status and Register (FPSCR).
      
      The error is in the preparation of the mask used to
      select the bits to be copied from the source to the FPSCR.
      
      Execution of the mtfsf instruction does not produce the same
      results on a MPC8548 platform (emulated floating point)
      as on MPC7410 or 440EP platforms (hardware floating point).
      
      This error has been detected using a Freescale MPC8548
      based platform and the patch below tested using that platform.
      
      The patch is based on the patch(es) provided by
      Gabriel Paubert and analysis by Gabriel, James Yang and David Laight.

      Pull device mapper changes from Mike Snitzer:
      
       - Fix dm-cache corruption caused by discard_block_size > cache_block_size
      
       - Fix a lock-inversion detected by LOCKDEP in dm-cache
      
       - Fix a dangling bio bug in the dm-thinp target's process_deferred_bios
         error path
      
       - Fix corruption due to non-atomic transaction commit which allowed a
         metadata superblock to be written before all other metadata was
         successfully written -- this is common to all targets that use the
         persistent-data library's transaction manager (dm-thinp, dm-cache and
         dm-era).
      
       - Various small cleanups in the DM core
      
       - Add the dm-era target which is useful for keeping track of which
         blocks were written within a user defined period of time called an
         'era'.  Use cases include tracking changed blocks for backup
         software, and partially invalidating the contents of a cache to
         restore cache coherency after rolling back a vendor snapshot.
      
       - Improve the on-disk layout of multithreaded writes to the
         dm-thin-pool by splitting the pool's deferred bio list to be a
         per-thin device list and then sorting that list using an rb_tree.
         The subsequent read throughput of the data written via multiple
         threads improved by ~70%.
      
       - Simplify the multipath target's handling of queuing IO by pushing
         requests back to the request queue rather than queueing the IO
         internally.

       "A large part of the arm-soc patches are nowadays DT changes, adding
        support for new SoCs, boards and devices without changing kernel
        source.  The plan is still to move the devicetree files out of the
        kernel tree and reduce the amount of churn going on here, but we keep
        finding reasons to delay doing that.
      
        Changes are really all over the place, with little sticking out
        particularly.  We have contributions from a total of 116 people in
        this branch.
      
        Unfortunately, the size of this branch also causes a significant
        number of conflicts at the moment, typically when subsystem
        maintainers merge patches that change the driver at the same time as
        the dts files.  In most cases this could be avoided because the dts
        changes are supposed to be compatible in both ways, and we are asking

         - Support for Qualcomm Krait processors (run perf on your phone!)
         - Support for Cortex-A12 (run perf stat on your FPGA!)
         - Support for perf_sample_event_took, allowing us to automatically decrease

           (run perf record on your FPGA!).
      
       - Basic uprobes support from David Long:
           This patch series adds basic uprobes support to ARM. It is based on
           patches developed earlier by Rabin Vincent. That approach of adding
           hooks into the kprobes instruction parsing code was not well received.
           This approach separates the ARM instruction parsing code in kprobes out
           into a separate set of functions which can be used by both kprobes and
           uprobes. Both kprobes and uprobes then provide their own semantic action
           tables to process the results of the parsing.
      
       - ARMv7M (microcontroller) updates from Uwe Kleine-König
      
       - OMAP DMA updates (recently added Vinod's Ack even though they've been
         sitting in linux-next for a few months) to reduce the reliance of
         omap-dma on the code in arch/arm.
