      Fix the regression created by "set S_DEAD on unlink()..." commit · d83c49f3
      Al Viro 提交于
      1) i_flags simply doesn't work for mount/unlink race prevention;
      we may have many links to file and rm on one of those obviously
      shouldn't prevent bind on top of another later on.  To fix it
      right way we need to mark _dentry_ as unsuitable for mounting
      upon; new flag (DCACHE_CANT_MOUNT) is protected by d_flags and
      i_mutex on the inode in question.  Set it (with dont_mount(dentry))
      in unlink/rmdir/etc., check (with cant_mount(dentry)) in places
      in namespace.c that used to check for S_DEAD.  Setting S_DEAD
      is still needed in places where we used to set it (for directories
      getting killed), since we rely on it for readdir/rmdir race
      prevention.
      
      2) rename()/mount() protection has another bogosity - we unhash
      the target before we'd checked that it's not a mountpoint.  Fixed.
      
      3) ancient bogosity in pivot_root() - we locked i_mutex on the
      right directory, but checked S_DEAD on the different (and wrong)
      one.  Noticed and fixed.

      If the kernel is large or the profiling step small, /proc/profile
      leaks data and readprofile shows silly stats, until readprofile -r
      has reset the buffer: clear the prof_buffer when it is vmalloc()ed.

      x86, mrst: Don't blindly access extended config space · e9b1d5d0
      H. Peter Anvin 提交于
      Do not blindly access extended configuration space unless we actively
      know we're on a Moorestown platform.  The fixed-size BAR capability
      lives in the extended configuration space, and thus is not applicable
      if the configuration space isn't appropriately sized.
      
      This fixes booting certain VMware configurations with CONFIG_MRST=y.
      
      Moorestown will add a fake PCI-X 266 capability to advertise the
      presence of extended configuration space.

      The L3 cache index disable feature of AMD CPUs has to be disabled if the
      kernel is running as guest on top of a hypervisor because northbridge
      devices are not available to the guest. Currently, this fixes a boot
      crash on top of Xen. In the future this will become an issue on KVM as
      well.
      
      Check if northbridge devices are present and do not enable the feature
      if there are none.
