We'd updated the prototype and the return value, but not the function

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.

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:
$ cat /proc/cpuinfo

mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe pni
monitor ds_cpl est tm2 cid xtpr
bogomips : 6637.46
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.

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()

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.

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.

sparc_ksyms.c used to declare weak alias to several gcc intrinsics. It
doesn't work with gcc4 anymore - it wants a declaration for the thing
we are aliasing to and that's not going to happen for something like
.mul, etc. Replaced with direct injection of weak alias on the assembler
level - .weak <alias> followed by <alias> = <aliased>; that works on all
gcc versions.

A problem was reported by Grant Grundler on an HP rx8620 using IOX
Core LAN partno(A7109-6) 5701 copper NIC. The tg3 driver mistakenly
detects this NIC as having a SerDes PHY and link does not come up as a
result.
The problem was caused by an incorrectly programmed eeprom that set the
NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit in the NIC_SRAM_DATA_CFG location.
This patch will override the NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit if a
valid PHY ID is read from the MII registers on older 570x chips where
the MII interface is not used on SerDes chips. On newer chips such as
the 5780 that use MII for both copper and SerDes, SerDes detection must
rely on the eeprom.
This patch will make the SerDes detection identical to versions 3.25 and
older.

The DM9000 driver is responding to ioctl() calls it should not be. This
can cause problems with the wireless tools incorrectly indentifying the
device as wireless capable, and crashing under certain operations.
This patch also moves the version printk() to the init call, so that
you only get it once for multiple devices, and to show it is loaded
if there are no defined dm9000s

Fix DM9000 driver usage of spinlocks, which mainly came to light
when running a kernel with spinlock debugging. These come down to:
1) Un-initialised spin lock
2) Several cases of using spin_xxx(lock) and not spin_xxx(&lock)
3) move the locking around the phy reg for read/write to only
keep the lock when actually reading or writing to the phy.

- Using the right register clearly improves chances of getting the MII
code and thus the driver working at all.

drivers/ide/ppc/pmac.c uses symbols ide_build_sglist,
__ide_dma_off_quietly, __ide_dma_on and __ide_dma_timeout when
CONFIG_BLK_DEV_IDEDMA_PMAC is defined. The declarations for these
symbols (in ide.h) depend on CONFIG_BLK_DEV_IDEDMA_PCI. There is a
missing dependency for this in drivers/ide/Kconfig which causes
drivers/ide/ppc/pmac.c to fail to build if CONFIG_BLK_DEV_IDEDMA_PMAC
is selected but CONFIG_BLK_DEV_IDEDMA_PCI is not.
