      Revert "mac80211: Fix accounting of the tailroom-needed counter" · 1e359a5d
      Johannes Berg 提交于
      This reverts commit ca34e3b5.
      
      It turns out that the p54 and cw2100 drivers assume that there's
      tailroom even when they don't say they really need it. However,
      there's currently no way for them to explicitly say they do need
      it, so for now revert this.
      
      This fixes https://bugzilla.kernel.org/show_bug.cgi?id=90331.

      net: ethernet: cpsw: fix hangs with interrupts · 7ce67a38
      Felipe Balbi 提交于
      The CPSW IP implements pulse-signaled interrupts. Due to
      that we must write a correct, pre-defined value to the
      CPDMA_MACEOIVECTOR register so the controller generates
      a pulse on the correct IRQ line to signal the End Of
      Interrupt.
      
      The way the driver is written today, all four IRQ lines
      are requested using the same IRQ handler and, because of
      that, we could fall into situations where a TX IRQ fires
      but we tell the controller that we ended an RX IRQ (or
      vice-versa). This situation triggers an IRQ storm on the
      reserved IRQ 127 of INTC which will in turn call ack_bad_irq()
      which will, then, print a ton of:
      
      	unexpected IRQ trap at vector 00
      
      In order to fix the problem, we are moving all calls to
      cpdma_ctlr_eoi() inside the IRQ handler and making sure
      we *always* write the correct value to the CPDMA_MACEOIVECTOR
      register. Note that the algorithm assumes that IRQ numbers and
      value-to-be-written-to-EOI are proportional, meaning that a
      write of value 0 would trigger an EOI pulse for the RX_THRESHOLD
      Interrupt and that's the IRQ number sitting in the 0-th index
      of our irqs_table array.
      
      This, however, is safe at least for current implementations of
      CPSW so we will refrain from making the check smarter (and, as
      a side-effect, slower) until we actually have a platform where
      IRQ lines are swapped.
      
      This patch has been tested for several days with AM335x- and
      AM437x-based platforms. AM57x was left out because there are
      still pending patches to enable ethernet in mainline for that
      platform. A read of the TRM confirms the statement on previous
      paragraph.

        domains framework allowing modular drivers to call one of its helper

           better way without using the CPUIDLE_FLAG_TIME_INVALID flag which
           allows that flag to be dropped from the ACPI cpuidle driver and
           from the core too (Len Brown).
      
         - New ACPI backlight blacklist entries for Samsung machines without a
           working native backlight interface that need to use the ACPI
           backlight instead (Aaron Lu).
      
         - New CPU IDs of future Intel Xeon CPUs for the Intel RAPL power
           capping driver (Jacob Pan).
      
         - Generic power domains framework modification to export the
           of_genpd_get_from_provider() function to modular drivers that will
           allow future driver modifications to be based on the mainline (Amit
           Daniel Kachhap).

      David S. Miller 提交于
      Users can request to bind to arbitrary multicast groups, so warning
      when the requested group number is out of range is not appropriate.
      
      And with the warning removed, and the 'err' variable properly given
      an initial value, we can remove 'found' altogether.
