      [PATCH] sched: disable preempt in idle tasks · 5bfb5d69
      Nick Piggin authored
      
      
      Run idle threads with preempt disabled.
      
      Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()).
      How did it ever work before?
      
      Might fix the CPU hotplugging hang which Nigel Cunningham noted.
      
      We think the bug hits if the idle thread is preempted after checking
      need_resched() and before going to sleep, then the CPU offlined.
      
      After calling stop_machine_run, the CPU eventually returns from preemption and
      into the idle thread and goes to sleep.  The CPU will continue executing
      previous idle and have no chance to call play_dead.
      
      By disabling preemption until we are ready to explicitly schedule, this bug is
      fixed and the idle threads generally become more robust.

      [PATCH] mm: init_mm without ptlock · 872fec16
      Hugh Dickins authored
      
      
      First step in pushing down the page_table_lock.  init_mm.page_table_lock has
      been used throughout the architectures (usually for ioremap): not to serialize
      kernel address space allocation (that's usually vmlist_lock), but because
      pud_alloc,pmd_alloc,pte_alloc_kernel expect caller holds it.
      
      Reverse that: don't lock or unlock init_mm.page_table_lock in any of the
      architectures; instead rely on pud_alloc,pmd_alloc,pte_alloc_kernel to take
      and drop it when allocating a new one, to check lest a racing task already
      did.  Similarly no page_table_lock in vmalloc's map_vm_area.
      
      Some temporary ugliness in __pud_alloc and __pmd_alloc: since they also handle
      user mms, which are converted only by a later patch, for now they have to lock
      differently according to whether or not it's init_mm.
      
      If sources get muddled, there's a danger that an arch source taking
      init_mm.page_table_lock will be mixed with common source also taking it (or
      neither take it).  So break the rules and make another change, which should
      break the build for such a mismatch: remove the redundant mm arg from
      pte_alloc_kernel (ppc64 scrapped its distinct ioremap_mm in 2.6.13).
      
      Exceptions: arm26 used pte_alloc_kernel on user mm, now pte_alloc_map; ia64
      used pte_alloc_map on init_mm, now pte_alloc_kernel; parisc had bad args to
      pmd_alloc and pte_alloc_kernel in unused USE_HPPA_IOREMAP code; ppc64
      map_io_page forgot to unlock on failure; ppc mmu_mapin_ram and ppc64 im_free
      took page_table_lock for no good reason.

      [PATCH] mm: m68k kill stram swap · f9c98d02
      Hugh Dickins authored
      
      
      Please, please now delete the Atari CONFIG_STRAM_SWAP code.  It may be
      excellent and ingenious code, but its reference to swap_vfsmnt betrays that it
      hasn't been built since 2.5.1 (four years old come December), it's delving
      deep into matters which are the preserve of core mm code, its only purpose is
      to give the more conscientious mm guys an anxiety attack from time to time;
      yet we keep on breaking it more and more.
      
      If you want to use RAM for swap, then if the MTD driver does not already
      provide just what you need, I'm sure David could be persuaded to add the
      extra.  But you'd also like to be able to allocate extents of that swap for
      other use: we can give you a core interface for that if you need.  But unbuilt
      for four years suggests to me that there's no need at all.
      
      I cannot swear the patch below won't break your build, but believe so.

      [PATCH] Kconfig fix (BLK_DEV_FD dependencies) · a08b6b79
      viro@ZenIV.linux.org.uk authored
      
      
      Sanitized and fixed floppy dependencies: split the messy dependencies for
      BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making
      BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC
      to arch/*/Kconfig.  While we are at it, fixed several obvious cases when
      BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
      are *not* going to have floppy.c compile, let alone work).
      
      If you can come up with better name for that ("this architecture might
      have working PC-compatible floppy disk controller"), you are more than
      welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch
      below...

      [NET]: add a top-level Networking menu to *config · d5950b43
      Sam Ravnborg authored
      
      
      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.

      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!
