      [S390] Improved oops output. · bb11e3bd
      Martin Schwidefsky 提交于
      This patch adds two improvements to the oops output. First it adds an
      additional line after the PSW which decodes the different fields of it.
      Second a disassembler is added that decodes the instructions surrounding
      the faulting PSW. The output of a test oops now looks like this:

      [S390] Reset infrastructure for re-IPL. · 15e9b586
      Heiko Carstens 提交于
      In case of re-IPL and diag308 doesn't work we have to reset all devices
      manually and wait synchronously that each reset finished.
      This patch adds the necessary infrastucture and the first exploiter of it.
      
      Subsystems that need to add a function that needs to be called at re-IPL
      may register/unregister this function via
      
      struct reset_call {
      	struct reset_call *next;
      	void (*fn)(void);
      };
      
      void register_reset_call(struct reset_call *reset);
      void unregister_reset_call(struct reset_call *reset);
      
      When the registered function get called the context is:
      
      - all cpus beside the current one are stopped
      - all machine checks and interrupts are disabled
      - prefixing is disabled
      - a default machine check handler is available for use
      
      The registered functions may not take any locks are sleep.
      
      For the common I/O layer part of this patch:
      
      Introduce a reset_call css_reset that does the following:
      - clear all subchannels
      - perform a rchp on all channel paths and wait for the resulting
        machine checks
      This replaces the calls to clear_all_subchannels() and
      cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now
      uses reipl_find_schid() to determine the subchannel id for a given
      device id.
      Also remove cio_reset_channel_paths() and friends since they are not
      needed anymore.

      [PATCH] sanitize building of fs/compat_ioctl.c · e6a6d2ef
      Christoph Hellwig 提交于
      Now that all these entries in the arch ioctl32.c files are gone [1], we can
      build fs/compat_ioctl.c as a normal object and kill tons of cruft.  We need a
      special do_ioctl32_pointer handler for s390 so the compat_ptr call is done.
      This is not needed but harmless on all other architectures.  Also remove some
      superflous includes in fs/compat_ioctl.c
      
      Tested on ppc64.
      
      [1] parisc still had it's PPP handler left, which is not fully correct
          for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd
          kick in for all netdevice users.  We can introduce a proper handler
          in one of the next patch series by adding a compat_ioctl method to
          struct net_device but for now let's just kill it - parisc doesn't
          compile in mainline anyway and I don't want this to block this
          patchset.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
