      ravb: Add missing free_irq() call to ravb_close() · 7fa816b9
      Geert Uytterhoeven authored
      When reopening the network device on ra7795/salvator-x, e.g. after a
      DHCP timeout:
      
          IP-Config: Reopening network devices...
          genirq: Flags mismatch irq 139. 00000000 (eth0:ch24:emac) vs. 00000000 (eth0:ch24:emac)
          ravb e6800000.ethernet eth0: cannot request IRQ eth0:ch24:emac
          IP-Config: Failed to open eth0
          IP-Config: No network devices available
      
      The "mismatch" is due to requesting an IRQ that is already in use,
      while IRQF_PROBE_SHARED wasn't set.
      
      However, the real cause is that ravb_close() doesn't release the R-Car
      Gen3-specific secondary IRQ.
      
      Add the missing free_irq() call to fix this.

      uapi glibc compat: fix compile errors when glibc net/if.h included before linux/if.h · 4a91cb61
      Mikko Rapeli authored
      glibc's net/if.h contains copies of definitions from linux/if.h and these
      conflict and cause build failures if both files are included by application
      source code. Changes in uapi headers, which fixed header file dependencies to
      include linux/if.h when it was needed, e.g. commit 1ffad83d, made the
      net/if.h and linux/if.h incompatibilities visible as build failures for
      userspace applications like iproute2 and xtables-addons.
      
      This patch fixes compile errors when glibc net/if.h is included before
      linux/if.h:
      
      ./linux/if.h:99:21: error: redeclaration of enumerator ‘IFF_NOARP’
      ./linux/if.h:98:23: error: redeclaration of enumerator ‘IFF_RUNNING’
      ./linux/if.h:97:26: error: redeclaration of enumerator ‘IFF_NOTRAILERS’
      ./linux/if.h:96:27: error: redeclaration of enumerator ‘IFF_POINTOPOINT’
      ./linux/if.h:95:24: error: redeclaration of enumerator ‘IFF_LOOPBACK’
      ./linux/if.h:94:21: error: redeclaration of enumerator ‘IFF_DEBUG’
      ./linux/if.h:93:25: error: redeclaration of enumerator ‘IFF_BROADCAST’
      ./linux/if.h:92:19: error: redeclaration of enumerator ‘IFF_UP’

      ./linux/if.h:107:23: error: redeclaration of enumerator ‘IFF_DYNAMIC’
      ./linux/if.h:106:25: error: redeclaration of enumerator ‘IFF_AUTOMEDIA’
      ./linux/if.h:105:23: error: redeclaration of enumerator ‘IFF_PORTSEL’
      ./linux/if.h:104:25: error: redeclaration of enumerator ‘IFF_MULTICAST’
      ./linux/if.h:103:21: error: redeclaration of enumerator ‘IFF_SLAVE’
      ./linux/if.h:102:22: error: redeclaration of enumerator ‘IFF_MASTER’
      ./linux/if.h:101:24: error: redeclaration of enumerator ‘IFF_ALLMULTI’
      ./linux/if.h:100:23: error: redeclaration of enumerator ‘IFF_PROMISC’
      
      The cases where linux/if.h is included before net/if.h need a similar fix in
      the glibc side, or the order of include files can be changed userspace
      code as a workaround.
      
      This change was tested in x86 userspace on Debian unstable with
      scripts/headers_compile_test.sh:
      
      $ make headers_install && \
        cd usr/include && ../../scripts/headers_compile_test.sh -l -k
      ...
      cc -Wall -c -nostdinc -I /usr/lib/gcc/i586-linux-gnu/5/include -I /usr/lib/gcc/i586-linux-gnu/5/include-fixed -I . -I /home/mcfrisk/src/linux-2.6/usr/headers_compile_test_include.2uX2zH -I /home/mcfrisk/src/linux-2.6/usr/headers_compile_test_include.2uX2zH/i586-linux-gnu -o /dev/null ./linux/if.h_libc_before_kernel.h
      PASSED libc before kernel test: ./linux/if.h
