This patch modifies the following.
1. Registers the mout_apll clksrc_clk clock.
2. The mout_mpll and mout_epll clocks were registered as 'struct clk'
types and then their parents were setup using the s3c_set_clksrc
function. This patch reduces the two steps into one by registering
the mout_mpll and mout_epll clocks using the s3c_register_clksrc
function.
3. As per point 2 above, the init_parents array is no longer required.
So the mout clocks are now put together in a new array named 'sysclks'.
The sysclks array will list the system level clocks and more
clocks will be added to it in the subsequent patches.
4. The clks array is left empty because of the movement of mpll and epll
clocks into the sysclks array. It is not deleted since subsequent
patches will add clocks into this array.

The system clock definitions are currently defined below the
peripheral clock definitions in the V210 clock code. For the V210
clock updates that follow this patch, it is required that the
system clock definitions such as the mout_apll and mout_mpll be
defined prior to the device clock definitions. This patch
re-arranges the system clock defintions for the clock updates that
follow this patch.

KEYS: Fix RCU handling in key_gc_keyring()
KEYS: Fix an RCU warning in the reading of user keys
key_gc_keyring() needs to either hold the RCU read lock or hold the keyring
semaphore if it's going to scan the keyring's list. Given that it only needs
to read the key list, and it's doing so under a spinlock, the RCU read lock is
the thing to use.
Furthermore, the RCU check added in e7b0a61b79 is
incorrect as holding the spinlock on key_serial_lock is not grounds for
assuming a keyring's pointer list can be read safely. Instead, a simple
rcu_dereference() inside of the previously mentioned RCU read lock is what we
want.

Some FSC hardware monitoring chips (Syleus at least) doesn't like
quick writes we typically use to probe for I2C chips. Use a regular
byte read instead for the address they live at (0x73). These are the
only known chips living at this address on PC systems.
For clarity, this fix should not be needed for kernels 2.6.30 and
later, as we started instantiating the hwmon devices explicitly based
on DMI data. Still, this fix is valuable in the following two cases:
* Support for recent FSC chips on older kernels. The DMI-based device
instantiation is more difficult to backport than the device support
itself.
* Case where the DMI-based device instantiation fails, whatever the
reason. We fall back to probing in that case, so it should work.

After discovering that a lot of i2c-drivers leave the pointer to their

It is assumed that the core may access the private data after remove()
as there are no guarantees for the lifetime of such pointers anyhow (see

If a rename operation is resent to the MDS following an MDS restart, the
client does not get a full reply (containing the resulting metadata) back.
In that case, a ceph_rename() needs to compensate by doing anything useful
that fill_inode() would have, like d_move().
It also needs to invalidate the dentry (to workaround the vfs_rename_dir()
bug) and clear the dir complete flag, just like fill_trace().

The snap realm split was checking i_snap_realm, not the list_head, to

The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed
the out-of-order issue of Loongson-2F described in chapter 15 of the
Loongson2F User Manual [1, 2], but introduced some problems.
The option changes all of the jump target to "addr & 0xcfffffff" through the
at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is
wrong. Avoids the problem via telling the assembler to not use the $at
register.

As documented in the Loongson 2F User Manual [2, 3], the old Loongson2F
series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds
in the kernel and binutils. This issue has been rectified in Loongson 2F
series 2F03 so no workarounds needed.
Now that the workarounds [1] adding the the -mfix-loongson2f-nop and
-mfix-loongson2f-jump options have been comitted to the binutils the CVS
repository), we can add the workarounds in the kernel.
The workarounds have no significant side effect on the system but may
decrease performance so we control them through a a new
CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable
it as necessary.
