      [NET]: add a top-level Networking menu to *config · d5950b43
      Sam Ravnborg 提交于
      Create a new top-level menu named "Networking" thus moving
      net related options and protocol selection way from the drivers
      menu and up on the top-level where they belong.
      
      To implement this all architectures has to source "net/Kconfig" before
      drivers/*/Kconfig in their Kconfig file. This change has been
      implemented for all architectures.
      
      Device drivers for ordinary NIC's are still to be found
      in the Device Drivers section, but Bluetooth, IrDA and ax25
      are located with their corresponding menu entries under the new
      networking menu item.

      [PATCH] Cleanup patch for process freezing · 3e1d1d28
      Christoph Lameter 提交于
      1. Establish a simple API for process freezing defined in linux/include/sched.h:
      
         frozen(process)		Check for frozen process
         freezing(process)		Check if a process is being frozen
         freeze(process)		Tell a process to freeze (go to refrigerator)
         thaw_process(process)	Restart process
         frozen_process(process)	Process is frozen now
      
      2. Remove all references to PF_FREEZE and PF_FROZEN from all
         kernel sources except sched.h
      
      3. Fix numerous locations where try_to_freeze is manually done by a driver
      
      4. Remove the argument that is no longer necessary from two function calls.
      
      5. Some whitespace cleanup
      
      6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
         cleared before setting PF_FROZEN, recalc_sigpending does not check
         PF_FROZEN).
      
      This patch does not address the problem of freeze_processes() violating the rule
      that a task may only modify its own flags by setting PF_FREEZE. This is not clean
      in an SMP environment. freeze(process) is therefore not SMP safe!

      [PATCH] kdump: Use real pt_regs from exception · 6e274d14
      Alexander Nyberg 提交于
      Makes kexec_crashdump() take a pt_regs * as an argument.  This allows to
      get exact register state at the point of the crash.  If we come from direct
      panic assertion NULL will be passed and the current registers saved before
      crashdump.
      
      This hooks into two places:
      die(): check the conditions under which we will panic when calling
      do_exit and go there directly with the pt_regs that caused the fatal
      fault.
      
      die_nmi(): If we receive an NMI lockup while in the kernel use the
      pt_regs and go directly to crash_kexec(). We're probably nested up badly
      at this point so this might be the only chance to escape with proper
      information.

      [PATCH] kexec: kexec ppc support · 70765aa4
      Eric W. Biederman 提交于
      I have tweaked this patch slightly to handle an empty list
      of pages to relocate passed to relocate_new_kernel.  And
      I have added ppc_md.machine_crash_shutdown.  To keep up with
      the changes in the generic kexec infrastructure.
      
      From: Albert Herranz <albert_herranz@yahoo.es>
      
      The following patch adds support for kexec on the ppc32 platform.
      
      Non-OpenFirmware based platforms are likely to work directly without
      additional changes on the kernel side.  The kexec-tools userland package
      may need to be slightly updated, though.
      
      For OpenFirmware based machines, additional work is still needed on the
      kernel side before kexec support is ready.  Benjamin Herrenschmidt is
      kindly working on that part.
      
      In order for a ppc platform to use the kexec kernel services it must
      implement some ppc_md hooks.  Otherwise, kexec will be explicitly disabled,
      as suggested by benh.
      
      There are 3+1 new ppc_md hooks that a platform supporting kexec may
      implement.  Two of them are mandatory for kexec to work.  See
      include/asm-ppc/machdep.h for details.
      
      - machine_kexec_prepare(image)
      
        This function is called to make any arrangements to the image before it
        is loaded.
      
        This hook _MUST_ be provided by a platform in order to activate kexec
        support for that platform.  Otherwise, the platform is considered to not
        support kexec and the kexec_load system call will fail (that makes all
        existing platforms by default non-kexec'able).
      
      - machine_kexec_cleanup(image)
      
        This function is called to make any cleanups on image after the loaded
        image data it is freed.  This hook is optional.  A platform may or may
        not provide this hook.
      
      - machine_kexec(image)
      
        This function is called to perform the _actual_ kexec.  This hook
        _MUST_ be provided by a platform in order to activate kexec support for
        that platform.
      
        If a platform provides machine_kexec_prepare but forgets to provide
        machine_kexec, a kexec will fall back to a reboot.
      
        A ready-to-use machine_kexec_simple() generic function is provided to,
        hopefully, simplify kexec adoption for embedded platforms.  A platform
        may call this function from its specific machine_kexec hook, like this:
      
      void myplatform_kexec(struct kimage *image)
      {
              machine_kexec_simple(image);
      }
      
      - machine_shutdown()
      
        This function is called to perform any machine specific shutdowns, not
        already done by drivers.  This hook is optional.  A platform may or may
        not provide this hook.
      
      An example (trimmed) platform specific module for a platform supporting
      kexec through the existing machine_kexec_simple follows:
      
      /* ... */
      
      #ifdef CONFIG_KEXEC
      int myplatform_kexec_prepare(struct kimage *image)
      {
              /* here, we can place additional preparations
      */
              return 0; /* yes, we support kexec */
      }
      
      void myplatform_kexec(struct kimage *image)
      {
              machine_kexec_simple(image);
      }
      #endif /* CONFIG_KEXEC */
      
      /* ... */
      
      void __init
      platform_init(unsigned long r3, unsigned long r4,
      unsigned long r5,
                    unsigned long r6, unsigned long r7)
      {
      
      /* ... */
      
      #ifdef CONFIG_KEXEC
              ppc_md.machine_kexec_prepare =
      myplatform_kexec_prepare;
              ppc_md.machine_kexec         =
      myplatform_kexec;
      #endif /* CONFIG_KEXEC */
      
      /* ... */
      
      }
      
      The kexec ppc kernel support has been heavily tested on the GameCube Linux
      port, and, as reported in the fastboot mailing list, it has been tested too
      on a Moto 82xx ppc by Rick Richardson.
