      ipv6: Pass proto to csum_ipv6_magic as __u8 instead of unsigned short · 1e940829
      Alexander Duyck authored
      
      
      This patch updates csum_ipv6_magic so that it correctly recognizes that
      protocol is a unsigned 8 bit value.
      
      This will allow us to better understand what limitations may or may not be
      present in how we handle the data.  For example there are a number of
      places that call htonl on the protocol value.  This is likely not necessary
      and can be replaced with a multiplication by ntohl(1) which will be
      converted to a shift by the compiler.

      ipv4: Update parameters for csum_tcpudp_magic to their original types · 01cfbad7
      Alexander Duyck authored
      
      
      This patch updates all instances of csum_tcpudp_magic and
      csum_tcpudp_nofold to reflect the types that are usually used as the source
      inputs.  For example the protocol field is populated based on nexthdr which
      is actually an unsigned 8 bit value.  The length is usually populated based
      on skb->len which is an unsigned integer.
      
      This addresses an issue in which the IPv6 function csum_ipv6_magic was
      generating a checksum using the full 32b of skb->len while
      csum_tcpudp_magic was only using the lower 16 bits.  As a result we could
      run into issues when attempting to adjust the checksum as there was no
      protocol agnostic way to update it.
      
      With this change the value is still truncated as many architectures use
      "(len + proto) << 8", however this truncation only occurs for values
      greater than 16776960 in length and as such is unlikely to occur as we stop
      the inner headers at ~64K in size.
      
      I did have to make a few minor changes in the arm, mn10300, nios2, and
      score versions of the function in order to support these changes as they
      were either using things such as an OR to combine the protocol and length,
      or were using ntohs to convert the length which would have truncated the
      value.
      
      I also updated a few spots in terms of whitespace and type differences for
      the addresses.  Most of this was just to make sure all of the definitions
      were in sync going forward.

      PCI: Include pci/hotplug Kconfig directly from pci/Kconfig · e7e127e3

      arch/hotplug: Call into idle with a proper state · fc6d73d6
      Thomas Gleixner authored
      
      
      Let the non boot cpus call into idle with the corresponding hotplug state, so
      the hotplug core can handle the further bringup. That's a first step to
      convert the boot side of the hotplugged cpus to do all the synchronization
      with the other side through the state machine. For now it'll only start the
      hotplug thread and kick the full bringup of the cpu.

      arch: Set IORESOURCE_SYSTEM_RAM flag for System RAM · 35d98e93
      Toshi Kani authored
      
      
      Set IORESOURCE_SYSTEM_RAM in flags of resource ranges with
      "System RAM", "Kernel code", "Kernel data", and "Kernel bss".
      
      Note that:
      
       - IORESOURCE_SYSRAM (i.e. modifier bit) is set in flags when
         IORESOURCE_MEM is already set. IORESOURCE_SYSTEM_RAM is defined
         as (IORESOURCE_MEM|IORESOURCE_SYSRAM).
      
       - Some archs do not set 'flags' for children nodes, such as
         "Kernel code".  This patch does not change 'flags' in this
         case.

      sh: fix smp_store_mb for !SMP · fb9b050c
      Michael S. Tsirkin authored
      sh variant of smp_store_mb() calls xchg() on !SMP which is stronger than
      implied by both the name and the documentation.
      
      commit 90a3ccb0
      
       ("sh: define __smp_xxx,
      fix smp_store_mb for !SMP") was supposed to fix it but
      left the bug in place.
      
      Drop smp_store_mb, so that code in asm-generic/barrier.h
      will define it correctly depending on CONFIG_SMP.

      [media] include/media: move platform_data to linux/platform_data/media · eb4b0ec7
      Mauro Carvalho Chehab authored
      
      
      Let's not mix platform_data headers with the core headers. Instead, let's
      create a subdir at linux/platform_data and move the headers to that
      common place, adding it to MAINTAINERS.
      
      The headers were moved with:
      	mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/
      
      And the references fixed with this script:
          MAIN_DIR="linux/platform_data/"
          PREV_DIR="media/"
          DIRS="media/"
      
          echo "Checking affected files" >&2

      	echo "Handling files..." >&2;
      	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";

      Let's not mix headers used by the core with those headers that

      [media] include/media: split I2C headers from V4L2 core · b5dcee22
      Mauro Carvalho Chehab authored
      
      
      Currently, include/media is messy, as it contains both the V4L2 core
      headers and some driver-specific headers on the same place. That makes
      harder to identify what core headers should be documented and what
      headers belong to I2C drivers that are included only by bridge/main
      drivers that would require the functions provided by them.
      
      Let's move those i2c specific files to its own subdirectory.
      
      The files to move were produced via the following script:
      	mkdir include/media/i2c
      	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
      	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
      	for i in include/media/*.h; do n=`basename $i`;  (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done
      
      And the references corrected via this script:
          MAIN_DIR="media/"
          PREV_DIR="media/"
          DIRS="i2c/"
      
          echo "Checking affected files" >&2
          for i in $DIRS; do
      	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
      		 n=`basename $j`
      		git grep -l $n
      	done
          done|sort|uniq >files && (
      	echo "Handling files..." >&2;
      	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
      	(
      		cd include/$MAIN_DIR;
      		for j in $DIRS; do
      			for i in $(ls $j); do
      				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
      			done;
      		done;
      		echo "cat > a && mv a \$i; done";
      	);
      	echo "Handling documentation..." >&2;
      	echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
      	(
      		cd include/$MAIN_DIR;
      		for j in $DIRS; do
      			for i in $(ls $j); do
      				echo "  perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
      			done;
      		done;
      		echo "cat > a && mv a \$i; done"
      	);
          ) >script && . ./script

      atomic, arch: Audit atomic_{read,set}() · 62e8a325
      Peter Zijlstra authored
      
      
      This patch makes sure that atomic_{read,set}() are at least
      {READ,WRITE}_ONCE().
      
      We already had the 'requirement' that atomic_read() should use
      ACCESS_ONCE(), and most archs had this, but a few were lacking.
      All are now converted to use READ_ONCE().
      
      And, by a symmetry and general paranoia argument, upgrade atomic_set()
      to use WRITE_ONCE().

      genirq: Remove irq argument from irq flow handlers · bd0b9ac4
      Thomas Gleixner authored
      
      
      Most interrupt flow handlers do not use the irq argument. Those few
      which use it can retrieve the irq number from the irq descriptor.
      
      Remove the argument.
      
      Search and replace was done with coccinelle and some extra helper
      scripts around it. Thanks to Julia for her help!
