      MIPS: ralink: mt7628a.dtsi: Add pinmux DT node · 380f072c
      Stefan Roese authored
      This patch adds the pinmux DT node using the generic "pinctrl-single"
      pinmux driver. For this the system-controller register area needs to be
      changed to not overlap with the pinmux registers.
      
      This patch is based on work done by John Crispin.

      MIPS: lantiq: Add SMP support for lantiq interrupt controller · 85cf2c37
      Petr Cvek authored
      Some lantiq devices have two ICU controllers. The IRQ signal is routed
      to both of them and user can chose which ICU will resend the IRQ to their
      respective VPE. The patch adds the support for the second ICU.
      
      The patch changes a register definition of the driver. Instead of an
      individual IM, the whole ICU is defined. This will only affects openwrt
      patched kernel (vanilla doesn't have additional .dts files).
      
      Also spinlocks has been added, both cores can RMW different bitfields
      in the same register. Added affinity set function. The new VPE cpumask
      will take into the action at the irq enable.
      
      The functionality was tested on 4.14 openwrt kernel and TP-W9980B modem.

      The macros LTQ_ICU_IM1_ISR and LTQ_ICU_OFFSET seems to be unused, remove
      them. Allong with that, remove _IM0 substring from the macro names. The

      mips: Remove q-accessors from non-64bit platforms · 1e279144
      Serge Semin authored
      There are some generic drivers in the kernel, which make use of the
      q-accessors or their derivatives. While at current asm/io.h the accessors
      are defined, their implementation is only applicable either for 64bit
      systems, or for systems with cpu_has_64bits flag set. Obviously there
      are MIPS systems which are neither of these, but still need to have
      those drivers supported. In this case the solution is to define some
      generic versions of the q-accessors, but with a limitation to be
      non-atomic. Such accessors are defined in the
      io-64-nonatomic-{hi-lo,lo-hi}.h file. The drivers which utilize the
      q-suffixed IO-methods are supposed to include the header file, so
      in case if these accessors aren't defined for the platform, the generic
      non-atomic versions are utilized. Currently the MIPS-specific asm/io.h
      file provides the q-accessors for any MIPS system even for ones, which
      in fact don't support them and raise BUG() in case if any of them is
      called. Due to this the generic versions of the accessors are never
      used while an attempt to call the IO-methods causes the kernel BUG().
      In order to fix this we need to define the q-accessors only for
      the MIPS systems, which actually support them, and don't define them
      otherwise, so to let the corresponding drivers to use the non-atomic
      q-suffixed accessors.

      FDDI: defza: Include linux/io-64-nonatomic-lo-hi.h · 262e4c38
      Paul Burton authored
      Currently arch/mips/include/asm/io.h provides 64b memory accessor
      functions such as readq & writeq even on MIPS32 platforms where those
      accessors cannot actually perform a 64b memory access. They instead
      BUG(). This is unfortunate for drivers which either #ifdef on the
      presence of these accessors, or can function with non-atomic
      implementations of them found in either linux/io-64-nonatomic-lo-hi.h or
      linux/io-64-nonatomic-hi-lo.h. As such we're preparing to remove the
      definitions of these 64b accessor functions for MIPS32 kernels.
      
      In preparation for this, include linux/io-64-nonatomic-lo-hi.h in
      defza.c in order to provide a non-atomic implementation of the
      readq_relaxed & writeq_relaxed functions that are used by this code. In
      practice this will have no runtime effect, since use of the 64b accessor
      functions is conditional upon sizeof(unsigned long) == 8, ie. upon
      CONFIG_64BIT=y. This means the calls to these non-atomic readq & writeq
      implementations will be optimized out anyway, but we need their
      definitions to keep the compiler happy.
      
      For 64bit kernels using this code this change should also have no effect
      because asm/io.h will continue to provide the definitions of
      readq_relaxed & writeq_relaxed, which linux/io-64-nonatomic-lo-hi.h
      checks for before defining itself.

      tracing: Silence GCC 9 array bounds warning · 0c97bf86
      Miguel Ojeda authored
      Starting with GCC 9, -Warray-bounds detects cases when memset is called
      starting on a member of a struct but the size to be cleared ends up
      writing over further members.
      
      Such a call happens in the trace code to clear, at once, all members
      after and including `seq` on struct trace_iterator:
      
          In function 'memset',
              inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3:
          ./include/linux/string.h:344:9: warning: '__builtin_memset' offset
          [8505, 8560] from the object at 'iter' is out of the bounds of
          referenced subobject 'seq' with type 'struct trace_seq' at offset
          4368 [-Warray-bounds]
            344 |  return __builtin_memset(p, c, size);
                |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      In order to avoid GCC complaining about it, we compute the address
      ourselves by adding the offsetof distance instead of referring
      directly to the member.
      
      Since there are two places doing this clear (trace.c and trace_kdb.c),
      take the chance to move the workaround into a single place in
      the internal header.

      Pule more SPDX updates from Greg KH:
       "Here is another set of reviewed patches that adds SPDX tags to
        different kernel files, based on a set of rules that are being used to
        parse the comments to try to determine that the license of the file is
        "GPL-2.0-or-later".
      
        Only the "obvious" versions of these matches are included here, a
        number of "non-obvious" variants of text have been found but those
        have been postponed for later review and analysis.
      
        These patches have been out for review on the linux-spdx@vger mailing
        list, and while they were created by automatic tools, they were
        hand-verified by a bunch of different people, all whom names are on
        the patches are reviewers"
