      container freezer: add TIF_FREEZE flag to all architectures · 83224b08
      Matt Helsley 提交于
      This patch series introduces a cgroup subsystem that utilizes the swsusp
      freezer to freeze a group of tasks.  It's immediately useful for batch job
      management scripts.  It should also be useful in the future for
      implementing container checkpoint/restart.
      
      The freezer subsystem in the container filesystem defines a cgroup file
      named freezer.state.  Reading freezer.state will return the current state
      of the cgroup.  Writing "FROZEN" to the state file will freeze all tasks
      in the cgroup.  Subsequently writing "RUNNING" will unfreeze the tasks in
      the cgroup.
      
      * Examples of usage :
      
         # mkdir /containers/freezer
         # mount -t cgroup -ofreezer freezer  /containers
         # mkdir /containers/0
         # echo $some_pid > /containers/0/tasks
      
      to get status of the freezer subsystem :
      
         # cat /containers/0/freezer.state
         RUNNING
      
      to freeze all tasks in the container :
      
         # echo FROZEN > /containers/0/freezer.state
         # cat /containers/0/freezer.state
         FREEZING
         # cat /containers/0/freezer.state
         FROZEN
      
      to unfreeze all tasks in the container :
      
         # echo RUNNING > /containers/0/freezer.state
         # cat /containers/0/freezer.state
         RUNNING
      
      This patch:
      
      The first step in making the refrigerator() available to all
      architectures, even for those without power management.
      
      The purpose of such a change is to be able to use the refrigerator() in a
      new control group subsystem which will implement a control group freezer.

      sparc, sparc64: use arch/sparc/include · a439fe51
      Sam Ravnborg 提交于
      The majority of this patch was created by the following script:
      
      ***
      ASM=arch/sparc/include/asm
      mkdir -p $ASM
      git mv include/asm-sparc64/ftrace.h $ASM
      git rm include/asm-sparc64/*
      git mv include/asm-sparc/* $ASM
      sed -ie 's/asm-sparc64/asm/g' $ASM/*
      sed -ie 's/asm-sparc/asm/g' $ASM/*
      ***
      
      The rest was an update of the top-level Makefile to use sparc
      for header files when sparc64 is being build.
      And a small fixlet to pick up the correct unistd.h from
      sparc64 code.

      sparc: join the remaining header files · f5e706ad
      Sam Ravnborg 提交于
      With this commit all sparc64 header files are moved to asm-sparc.
      The remaining files (71 files) were too different to be trivially
      merged so divide them up in a _32.h and a _64.h file which
      are both included from the file with no bit size.
      
      The following script were used:
      cd include
      FILES=`wc -l asm-sparc64/*h | grep -v '^     1' | cut -b 20-`
      
      for FILE in ${FILES}; do
        echo $FILE:
        BASE=`echo $FILE | cut -d '.' -f 1`
        FN32=${BASE}_32.h
        FN64=${BASE}_64.h
        GUARD=___ASM_SPARC_`echo $BASE | tr '-' '_' | tr [:lower:] [:upper:]`_H
        git mv asm-sparc/$FILE asm-sparc/$FN32
        git mv asm-sparc64/$FILE asm-sparc/$FN64
        echo git mv done
        printf "#ifndef %s\n" $GUARD                             >   asm-sparc/$FILE
        printf "#define %s\n" $GUARD                             >>  asm-sparc/$FILE
        printf "#if defined(__sparc__) && defined(__arch64__)\n" >>  asm-sparc/$FILE
        printf "#include <asm-sparc/%s>\n" $FN64                 >>  asm-sparc/$FILE
        printf "#else\n"                                         >>  asm-sparc/$FILE
        printf "#include <asm-sparc/%s>\n" $FN32                 >>  asm-sparc/$FILE
        printf "#endif\n"                                        >>  asm-sparc/$FILE
        printf "#endif\n"                                        >>  asm-sparc/$FILE
        git add asm-sparc/$FILE
        echo new file done
        printf "#include <asm-sparc/%s>\n" $FILE                 >  asm-sparc64/$FILE
        git add asm-sparc64/$FILE
        echo sparc64 file done
      done
      
      The guard contains three '_' to avoid conflict with existing guards.
      In additing the two Kbuild files are emptied to avoid breaking
      headers_* targets.
      We will reintroduce the exported header files when the necessary
      kbuild changes are merged.

      sparc: Remove old style signal frame support. · 5526b7e4
      David S. Miller 提交于
      Back around the same time we were bootstrapping the first 32-bit sparc
      Linux kernel with a SunOS userland, we made the signal frame match
      that of SunOS.
      
      By the time we even started putting together a native Linux userland
      for 32-bit Sparc we realized this layout wasn't sufficient for Linux's
      needs.
      
      Therefore we changed the layout, yet kept support for the old style
      signal frame layout in there.  The detection mechanism is that we had
      sys_sigaction() start passing in a negative signal number to indicate
      "new style signal frames please".
      
      Anyways, no binaries exist in the world that use the old stuff.  In
      fact, I bet Jakub Jelinek and myself are the only two people who ever
      had such binaries to be honest.
      
      So let's get rid of this stuff.
      
      I added an assertion using WARN_ON_ONCE() that makes sure 32-bit
      applications are passing in that negative signal number still.

      [SPARC64]: Eliminate NR_CPUS limitations. · 22adb358
      David S. Miller 提交于
      Cheetah systems can have cpuids as large as 1023, although physical
      systems don't have that many cpus.
      
      Only three limitations existed in the kernel preventing arbitrary
      NR_CPUS values:
      
      1) dcache dirty cpu state stored in page->flags on
         D-cache aliasing platforms.  With some build time
         calculations and some build-time BUG checks on
         page->flags layout, this one was easily solved.
      
      2) The cheetah XCALL delivery code could only handle
         a cpumask with up to 32 cpus set.  Some simple looping
         logic clears that up too.
      
      3) thread_info->cpu was a u8, easily changed to a u16.
      
      There are a few spots in the kernel that still put NR_CPUS
      sized arrays on the kernel stack, but that's not a sparc64
      specific problem.

      [PATCH] streamline preempt_count type across archs · dcd497f9
      Jesper Juhl 提交于
      The preempt_count member of struct thread_info is currently either defined
      as int, unsigned int or __s32 depending on arch.  This patch makes the type
      of preempt_count an int on all archs.
      
      Having preempt_count be an unsigned type prevents the catching of
      preempt_count < 0 bugs, and using int on some archs and __s32 on others is
      not exactely "neat" - much nicer when it's just int all over.
      
      A previous version of this patch was already ACK'ed by Robert Love, and the
      only change in this version of the patch compared to the one he ACK'ed is
      that this one also makes sure the preempt_count member is consistently
      commented.

      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!
