      stmmac: avoid ipq806x constant overflow warning · 49e4a229
      Arnd Bergmann authored
      Building dwmac-ipq806x on a 64-bit architecture produces a harmless
      warning from gcc:
      
      stmmac/dwmac-ipq806x.c: In function 'ipq806x_gmac_probe':
      include/linux/bitops.h:6:19: warning: overflow in implicit constant conversion [-Woverflow]
        val = QSGMII_PHY_CDR_EN |
      stmmac/dwmac-ipq806x.c:333:8: note: in expansion of macro 'QSGMII_PHY_CDR_EN'
       #define QSGMII_PHY_CDR_EN   BIT(0)
       #define BIT(nr)   (1UL << (nr))
      
      This is a result of the type conversion rules in C, when we take the
      logical OR of multiple different types. In particular, we have
      and unsigned long
      
      	QSGMII_PHY_CDR_EN == BIT(0) == (1ul << 0) == 0x0000000000000001ul
      
      and a signed int
      
      	0xC << QSGMII_PHY_TX_DRV_AMP_OFFSET == 0xc0000000
      
      which together gives a signed long value
      
      	0xffffffffc0000001l
      
      and when this is passed into a function that takes an unsigned int type,
      gcc warns about the signed overflow and the loss of the upper 32-bits that
      are all ones.
      
      This patch adds 'ul' type modifiers to the literal numbers passed in
      here, so now the expression remains an 'unsigned long' with the upper
      bits all zero, and that avoids the signed overflow and the warning.

      ====================
      Netfilter fixes for net
      
      The following patchset contains Netfilter fixes for your net tree. This
      large batch that includes fixes for ipset, netfilter ingress, nf_tables
      dynamic set instantiation and a longstanding Kconfig dependency problem.
      More specifically, they are:
      
      1) Add missing check for empty hook list at the ingress hook, from
         Florian Westphal.
      
      2) Input and output interface are swapped at the ingress hook,
         reported by Patrick McHardy.
      
      3) Resolve ipset extension alignment issues on ARM, patch from Jozsef
         Kadlecsik.
      
      4) Fix bit check on bitmap in ipset hash type, also from Jozsef.
      
      5) Release buckets when all entries have expired in ipset hash type,
         again from Jozsef.
      
      6) Oneliner to initialize conntrack tuple object in the PPTP helper,
         otherwise the conntrack lookup may fail due to random bits in the
         structure holes, patch from Anthony Lineham.
      
      7) Silence a bogus gcc warning in nfnetlink_log, from Arnd Bergmann.
      
      8) Fix Kconfig dependency problems with TPROXY, socket and dup, also
         from Arnd.
      
      9) Add __netdev_alloc_pcpu_stats() to allow creating percpu counters
         from atomic context, this is required by the follow up fix for
         nf_tables.
      
      10) Fix crash from the dynamic set expression, we have to add new clone
          operation that should be defined when a simple memcpy is not enough.
          This resolves a crash when using per-cpu counters with new Patrick
          McHardy's flow table nft support.

       "Defconfig updates are kept separate from other branches mostly to
        avoid conflicts between the different categories (driver branch

        platforms.  multi_v7_defconfig, our "generic" config for most 32-bit
        platforms has been gone through by Marvell Berlin maintainers and
        added most options they need to run on their hardware.  Broadcom NSP
        is also added there, and the new Atmel SAMA5D2 (added last release).
        Rockchip also has display and other devices supported in that config.

      Pull ARM SoC driver updates from Olof Johansson:
       "As we've enabled multiplatform kernels on ARM, and greatly done away
        with the contents under arch/arm/mach-*, there's still need for
        SoC-related drivers to go somewhere.
      
        Many of them go in through other driver trees, but we still have
        drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
        that might be shared between ARM and ARM64 (or just in general makes
        sense to not have under the architecture directory).
      
        This branch contains mostly such code:
      
         - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to
           communicate with power management blocks on these SoCs for use by
           clock, regulator and bus frequency drivers.
      
         - Allwinner Reduced Serial Bus driver, again used to communicate with
           PMICs.
      
         - Drivers for ARM's SCPI (System Control Processor).  Not to be
           confused with PSCI (Power State Coordination Interface).  SCPI is
           used to communicate with the assistant embedded cores doing power
           management, and we have yet to see how many of them will implement
           this for their hardware vs abstracting in other ways (or not at all
           like in the past).
      
         - To make confusion between SCPI and PSCI more likely, this release
           also includes an update of PSCI to interface version 1.0.
      
         - Rockchip support for power domains.
      
         - A driver to talk to the firmware on Raspberry Pi"
