KEYS: Fix RCU handling in key_gc_keyring()
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
e7b0a61b7929632d36cf052d9e2820ef0a9c1bfe 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.

ppp_generic: handle non-linear skbs when passing them to pppd
Frequently when using PPPoE with an interface MTU greater than 1500,
the skb is likely to be non-linear. If the skb needs to be passed to
pppd then the skb data must be read correctly.
The previous commit fixes an issue with accidentally sending skbs
to pppd based on an invalid read of the protocol type. When that
error occurred pppd was reading invalid skb data too.

ppp_generic: pull 2 bytes so that PPP_PROTO(skb) is valid
In ppp_input(), PPP_PROTO(skb) may refer to invalid data in the skb.
If this happens and (proto >= 0xc000 || proto == PPP_CCPFRAG) then
the packet is passed directly to pppd.
This occurs frequently when using PPPoE with an interface MTU

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.

MIPS: Use CKSEG1ADDR for uncached handler
"MIPS: Calculate proper ebase value for 64-bit kernels"
9af43ea080dd5d6c7b34f38261780e5dd43537bc (lmo) rsp.
f6be75d03c8870be91e6e2a195648ece04b6bb16 (kernel.org) broke some 64-bit
MIPS systems.
Before this we were using XKPHYS/cached as ebase and computed the uncached
xphsys/unchached address for that area. After that commit ebase became a
32-bit compat address and convert does not work anymore. We now should use
CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit.

MIPS: Check for accesses beyond the end of the PGD.
For some combinations of PAGE_SIZE and vmbits, it is possible to have
userspace access that are beyond what is covered by the PGD, but within
vmbits. Such an access would cause the TLB refill handler to load garbage
values for PMD and PTE potentially giving userspace access to parts of the
physical address space to which it is not entitled.
In the TLB refill hot path, we add a single dsrl instruction so we can
check if any bits outside of the range covered by the PGD are set. In
the vmalloc side we then separate the bad case from the normal vmalloc
case and call tlb_do_page_fault_0 if warranted. This slows us down a
bit, but has the benefit of yielding deterministic behavior.

MIPS: die() does not call die notifier chain
The MIPS implementation of die() forgets to call notify_die() and thus notifiers
registered via register_die_notifier() are not called. This results in kgdb not
being activated on exceptions.
The only subtlety is that notify_die declares its regs argument w/o const, so
the const had to be removed from mips die() as well.

MIPS: Don't vmap things at address zero.
In the 64-bit kernel we use swapper_pg_dir for three different things.
1) xuseg mappings for kernel threads.
2) vmap mappings for all kernel-space accesses in xkseg.
3) vmap mappings for kernel modules in ksseg (kseg2).
Due to how the TLB refill handlers work, any mapping established in
xkseg or ksseg will also establish a xuseg mapping that should never
be used by the kernel.
In order to be able to use exceptions to trap NULL pointer
dereferences, we need to ensure that nothing is mapped at address
zero. Since vmap mappings in xkseg are reflected in xuseg, this means
we need to ensure that there are no vmap mappings established at the
start of xkseg. So we move back VMALLOC_START to avoid establishing
vmap mappings at the start of xkseg.
