      [PATCH] convert signal handling of NODEFER to act like other Unix boxes. · 69be8f18
      Steven Rostedt 提交于
      It has been reported that the way Linux handles NODEFER for signals is
      not consistent with the way other Unix boxes handle it.  I've written a
      program to test the behavior of how this flag affects signals and had
      several reports from people who ran this on various Unix boxes,
      confirming that Linux seems to be unique on the way this is handled.
      
      The way NODEFER affects signals on other Unix boxes is as follows:
      
      1) If NODEFER is set, other signals in sa_mask are still blocked.
      
      2) If NODEFER is set and the signal is in sa_mask, then the signal is
      still blocked. (Note: this is the behavior of all tested but Linux _and_
      NetBSD 2.0 *).
      
      The way NODEFER affects signals on Linux:
      
      1) If NODEFER is set, other signals are _not_ blocked regardless of
      sa_mask (Even NetBSD doesn't do this).
      
      2) If NODEFER is set and the signal is in sa_mask, then the signal being
      handled is not blocked.
      
      The patch converts signal handling in all current Linux architectures to
      the way most Unix boxes work.
      
      Unix boxes that were tested:  DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU
      3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX.
      
      * NetBSD was the only other Unix to behave like Linux on point #2. The
      main concern was brought up by point #1 which even NetBSD isn't like
      Linux.  So with this patch, we leave NetBSD as the lonely one that
      behaves differently here with #2.

      [PATCH] x86_64: Tell VM about holes in nodes · 485761bd
      Andi Kleen 提交于
      Some nodes can have large holes on x86-64.
      
      This fixes problems with the VM allowing too many dirty pages because it
      overestimates the number of available RAM in a node.  In extreme cases you
      can end up with all RAM filled with dirty pages which can lead to deadlocks
      and other nasty behaviour.
      
      This patch just tells the VM about the known holes from e820.  Reserved
      (like the kernel text or mem_map) is still not taken into account, but that
      should be only a few percent error now.
      
      Small detail is that the flat setup uses the NUMA free_area_init_node() now
      too because it offers more flexibility.
      
      (akpm: lotsa thanks to Martin for working this problem out)
