      [PATCH] getting rid of all casts of k[cmz]alloc() calls · 5cbded58
      Robert P. J. Day authored
      
      
      Run this:
      
      	#!/bin/sh
      	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
      	  echo "De-casting $f..."
      	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
      	done
      
      And then go through and reinstate those cases where code is casting pointers
      to non-pointers.
      
      And then drop a few hunks which conflicted with outstanding work.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells authored
      
      
      Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
      of passing regs around manually through all ~1800 interrupt handlers in the
      Linux kernel.
      
      The regs pointer is used in few places, but it potentially costs both stack
      space and code to pass it around.  On the FRV arch, removing the regs parameter
      from all the genirq function results in a 20% speed up of the IRQ exit path
      (ie: from leaving timer_interrupt() to leaving do_IRQ()).
      
      Where appropriate, an arch may override the generic storage facility and do
      something different with the variable.  On FRV, for instance, the address is
      maintained in GR28 at all times inside the kernel as part of general exception
      handling.
      
      Having looked over the code, it appears that the parameter may be handed down
      through up to twenty or so layers of functions.  Consider a USB character
      device attached to a USB hub, attached to a USB controller that posts its
      interrupts through a cascaded auxiliary interrupt controller.  A character
      device driver may want to pass regs to the sysrq handler through the input
      layer which adds another few layers of parameter passing.
      
      I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
      main part of the code on FRV and i386, though I can't test most of the drivers.
      I've also done partial conversion for powerpc and MIPS - these at least compile
      with minimal configurations.
      
      This will affect all archs.  Mostly the changes should be relatively easy.
      Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
      
      	struct pt_regs *old_regs = set_irq_regs(regs);
      
      And put the old one back at the end:
      
      	set_irq_regs(old_regs);
      
      Don't pass regs through to generic_handle_irq() or __do_IRQ().
      
      In timer_interrupt(), this sort of change will be necessary:
      
      	-	update_process_times(user_mode(regs));
      	-	profile_tick(CPU_PROFILING, regs);
      	+	update_process_times(user_mode(get_irq_regs()));
      	+	profile_tick(CPU_PROFILING);
      
      I'd like to move update_process_times()'s use of get_irq_regs() into itself,
      except that i386, alone of the archs, uses something other than user_mode().
      
      Some notes on the interrupt handling in the drivers:
      
       (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
           the input_dev struct.
      
       (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
           something different depending on whether it's been supplied with a regs
           pointer or not.
      
       (*) Various IRQ handler function pointers have been moved to type
           irq_handler_t.

      ok this appears to be hostap playing games... it has 2 network devices
      for one piece of hardware and one calls the other via the networking
      layer; there is thankfully a natural ordering between the two, so just
      making the slave one a separate type ought to make this work.

      [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason · 733482e4
      Olaf Hering authored
      
      
      This patch removes almost all inclusions of linux/version.h.  The 3
      #defines are unused in most of the touched files.
      
      A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
      unfortunatly in linux/version.h.
      
      There are also lots of #ifdef for long obsolete kernels, this was not
      touched.  In a few places, the linux/version.h include was move to where
      the LINUX_VERSION_CODE was used.
      
      quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`
      
      search pattern:
      /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h

      net/ieee80211 that has more or less identical implementation (since
      it is based on the Host AP implementation). Remove Host AP specific

      Jouni Malinen authored
      
      
      Preparations for starting to use net/ieee80211 instead of private
      IEEE 802.11 implementation. Include net/ieee80211.h and
      net/ieee80211_crypt.h into files that will be needed these in the
      future. Remove duplicate definitions from hostap_common.h and
      rename WLAN_FC_GET_{TYPE,STYPE} macros for now sinc net/ieee80211.h
      is using incompatible definitions. This will be resolved in the
      future by updating Host AP to use the versions that do not shift
      type/stype.

      Pavel Roskin authored
      
      
      Warning fix for 64-bit platforms
      
      Hello!
      
      The patch fixes following warning seen on 64-bit platforms (in my case -
      x86_64, gcc-4.0):
      
      In file included from /usr/local/src/hostap/driver/modules/hostap_cs.c:203:
      /usr/local/src/hostap/driver/modules/hostap_hw.c: In function ?prism2_transmit_cb?:
      /usr/local/src/hostap/driver/modules/hostap_hw.c:1674: warning: cast from pointer to integer of different size
      /usr/local/src/hostap/driver/modules/hostap_hw.c: In function ?prism2_transmit?:
      /usr/local/src/hostap/driver/modules/hostap_hw.c:1758: warning: cast to pointer from integer of different size
      
      prism2_transmit_cb uses a (void *) argument to get an integer.   A
      simple fix would be to use double cast from pointer to long and then to
      int (and vice versa when int is passed as a pointer).  But I prefer a
      slightly longer patch.
      
      I believe that whenever an argument can hold both a pointer and an
      integer, it should be declared long.  long can hold both pointers and
      integers (except win64, but we are not coding for Windows), it can be
      cast to both of them and it's never assumed to be a valid pointer, which
      could be useful for some automatic code checkers.

      [PATCH] hostap update · 0cd545d6
      Dave Hansen authored
      
      
      Create sysfs "device" files for hostap
      
      I was writing some scripts to automatically build kismet source lines,
      and I noticed that hostap devices don't have device files, unlike my
      prism54 and ipw2200 cards:
      
      $ ls -l /sys/class/net/eth0/device
      /sys/class/net/eth0/device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:02:01.0
      $ ls -l /sys/class/net/wifi0
      ls: /sys/class/net/wifi0/device: No such file or directory
      $ ls -l /sys/class/net/wlan0
      ls: /sys/class/net/wlan0/device: No such file or directory
      
      The following (quite small) patch makes sure that both the wlan and wifi
      net devices have that pointer to the bus device.
      
      This way, I can do things like
      
              for i in /sys/class/net/*; do
                      if ! [ -e $i/device/drive ]; then
                              continue;
                      fi;
                      driver=$(basename $(readlink $i/device/driver))
                      case $driver in
                              hostap*)
                                      echo -- hostap,$i,$i-$driver
                                      break;
                              ipw2?00)
                                      echo -- $driver,$i,$i-$driver
                                      break;
                              prism54)
                                      echo prism54g,$i
                      esac
              done
      
      Which should generate a working set of source lines for kismet no matter
      what order I plug the cards in.
      
      It might also be handy to have a link between the two net devices, but
      that's a patch for another day.
      
      That patch is against 2.6.13-rc1-mm1.
