      uml: style fixes pass 3 · ba180fd4
      Jeff Dike authored
      
      
      Formatting changes in the files which have been changed in the course
      of folding foo_skas functions into their callers.  These include:
      	copyright updates
      	header file trimming
      	style fixes
      	adding severity to printks
      
      These changes should be entirely non-functional.

      uml: remove code made redundant by CHOOSE_MODE removal · 77bf4400
      Jeff Dike authored
      
      
      This patch makes a number of simplifications enabled by the removal of
      CHOOSE_MODE.  There were lots of functions that looked like
      
      	int foo(args){
      		foo_skas(args);
      	}
      
      The bodies of foo_skas are now folded into foo, and their declarations (and
      sometimes entire header files) are deleted.
      
      In addition, the union uml_pt_regs, which was a union between the tt and skas
      register formats, is now a struct, with the tt-mode arm of the union being
      removed.
      
      It turns out that usr2_handler was unused, so it is gone.

      uml: throw out CHOOSE_MODE · 6aa802ce
      Jeff Dike authored
      
      
      The next stage after removing code which depends on CONFIG_MODE_TT is removing
      the CHOOSE_MODE abstraction, which provided both compile-time and run-time
      branching to either tt-mode or skas-mode code.
      
      This patch removes choose-mode.h and all inclusions of it, and replaces all
      CHOOSE_MODE invocations with the skas branch.  This leaves a number of trivial
      functions which will be dealt with in a later patch.
      
      There are some changes in the uaccess and tls support which go somewhat beyond
      this and eliminate some of the now-redundant functions.

      uml: throw out CONFIG_MODE_TT · 42fda663
      Jeff Dike authored
      
      
      This patchset throws out tt mode, which has been non-functional for a while.
      
      This is done in phases, interspersed with code cleanups on the affected files.
      
      The removal is done as follows:
      	remove all code, config options, and files which depend on
      CONFIG_MODE_TT
      	get rid of the CHOOSE_MODE macro, which decided whether to
      call tt-mode or skas-mode code, and replace invocations with their
      skas portions
      	replace all now-trivial procedures with their skas equivalents
      
      There are now a bunch of now-redundant pieces of data structures, including
      mode-specific pieces of the thread structure, pt_regs, and mm_context.  These
      are all replaced with their skas-specific contents.
      
      As part of the ongoing style compliance project, I made a style pass over all
      files that were changed.  There are three such patches, one for each phase,
      covering the files affected by that phase but no later ones.
      
      I noticed that we weren't freeing the LDT state associated with a process when
      it exited, so that's fixed in one of the later patches.
      
      The last patch is a tidying patch which I've had for a while, but which caused
      inexplicable crashes under tt mode.  Since that is no longer a problem, this
      can now go in.
      
      This patch:
      
      Start getting rid of tt mode support.
      
      This patch throws out CONFIG_MODE_TT and all config options, code, and files
      which depend on it.
      
      CONFIG_MODE_SKAS is gone and everything that depends on it is included
      unconditionally.
      
      The few changed lines are in re-written Kconfig help, lines which needed
      something skas-related removed from them, and a few more which weren't
      strictly deletions.

      [PATCH] Don't attempt to power off if power off is not implemented · 5e38291d
      Eric W. Biederman authored
      
      
      The problem.  It is expected that /sbin/halt -p works exactly like
      /sbin/halt, when the kernel does not implement power off functionality.
      
      The kernel can do a lot of work in the reboot notifiers and in
      device_shutdown before we even get to machine_power_off.  Some of that
      shutdown is not safe if you are leaving the power on, and it definitely
      gets in the way of using sysrq or pressing ctrl-alt-del.  Since the
      shutdown happens in generic code there is no way to fix this in
      architecture specific code :(
      
      Some machines are kernel oopsing today because of this.
      
      The simple solution is to turn LINUX_REBOOT_CMD_POWER_OFF into
      LINUX_REBOOT_CMD_HALT if power_off functionality is not implemented.
      
      This has the unfortunate side effect of disabling the power off
      functionality on architectures that leave pm_power_off to null and still
      implement something in machine_power_off.  And it will break the build on
      some architectures that don't have a pm_power_off variable at all.
      
      On both counts I say tough.
      
      For architectures like alpha that don't implement the pm_power_off variable
      pm_power_off is declared in linux/pm.h and it is a generic part of our
      power management code, and all architectures should implement it.
      
      For architectures like parisc that have a default power off method in
      machine_power_off if pm_power_off is not implemented or fails.  It is easy
      enough to set the pm_power_off variable.  And nothing bad happens there,
      the machines just stop powering off.
      
      The current semantics are impossible without a flag at the top level so we
      can avoid the problem code if a power off is not implemented.  pm_power_off
      is as good a flag as any with the bonus that it works without modification
      on at least x86, x86_64, powerpc, and ppc today.
      
      Andrew can you pick this up and put this in the mm tree.  Kernels that
      don't compile or don't power off seem saner than kernels that oops or
      panic.  Until we get the arch specific patches for the problem
      architectures this probably isn't smart to push into the stable kernel.
      Unfortunately I don't have the time at the moment to walk through every
      architecture and make them work.  And even if I did I couldn't test it :(
      
      From: Hirokazu Takata <takata@linux-m32r.org>
      
          Add pm_power_off() for build fix of arch/m32r/kernel/process.c.

      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!
