      befs: fix up missed follow_link declaration change · db873896
      Linus Torvalds authored 
      We'd updated the prototype and the return value, but not the function
declaration itself.

      [PATCH] x86_64: Fix race in TSC synchronization · 1eecd73c
      Andi Kleen authored 
      Plug a race in TSC synchronization

We need to do tsc_sync_wait() before the CPU is set online to prevent
multiple CPUs from doing it in parallel - which won't work because TSC
sync has global unprotected state.

      [PATCH] Mobil Pentium 4 HT and the NMI · cd3716ab
      Steven Rostedt authored 
      I'm trying to get the nmi working with my laptop (IBM ThinkPad G41) and after
debugging it a while, I found that the nmi code doesn't want to set it up for
this particular CPU.

Here I have:

And the following code shows:

$ cat linux-2.6.13-rc6/arch/i386/kernel/nmi.c

[...]

void setup_apic_nmi_watchdog (void)
{
        switch (boot_cpu_data.x86_vendor) {
        case X86_VENDOR_AMD:
                if (boot_cpu_data.x86 != 6 && boot_cpu_data.x86 != 15)
                        return;
                setup_k7_watchdog();
                break;
        case X86_VENDOR_INTEL:
                 switch (boot_cpu_data.x86) {
                case 6:
                        if (boot_cpu_data.x86_model > 0xd)
                                return;

                        setup_p6_watchdog();
                        break;
                case 15:
                        if (boot_cpu_data.x86_model > 0x3)
                                return;

Here I get boot_cpu_data.x86_model == 0x4.  So I decided to change it and
reboot.  I now seem to have a working NMI.  So, unless there's something know
to be bad about this processor and the NMI.  I'm submitting the following
patch.

      [PATCH] Fix up symlink function pointers · 008b150a
      Al Viro authored 
      This fixes up the symlink functions for the calling convention change:

 * afs, autofs4, befs, devfs, freevxfs, jffs2, jfs, ncpfs, procfs,
   smbfs, sysvfs, ufs, xfs - prototype change for ->follow_link()
 * befs, smbfs, xfs - same for ->put_link()

      Fix nasty ncpfs symlink handling bug. · cc314eef
      Linus Torvalds authored 
      This bug could cause oopses and page state corruption, because ncpfs
used the generic page-cache symlink handlign functions.  But those
functions only work if the page cache is guaranteed to be "stable", ie a
page that was installed when the symlink walk was started has to still
be installed in the page cache at the end of the walk.

We could have fixed ncpfs to not use the generic helper routines, but it
is in many ways much cleaner to instead improve on the symlink walking
helper routines so that they don't require that absolute stability.

We do this by allowing "follow_link()" to return a error-pointer as a
cookie, which is fed back to the cleanup "put_link()" routine.  This
also simplifies NFS symlink handling.

      [PATCH] jffs2: fix symlink error handling · 2fb1e308
      Al Viro authored 
      The current calling conventions for ->follow_link() are already fairly
complex.

What we have is
	1) you can return -error; then you must release nameidata yourself
	   and ->put_link() will _not_ be called.
	2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0
	3) you can do nd_set_link(nd, path) and return 0
	4) you can return 0 (after having moved nameidata yourself)

jffs2 follow_link() is broken - it has an exit where it returns
-EIO and leaks nameidata.
