Eddie Dong 8668a3c468 KVM: VMX: Reset mmu context when entering real mode
Resetting an SMP guest will force AP enter real mode (RESET) with
paging enabled in protected mode. While current enter_rmode() can
only handle mode switch from nonpaging mode to real mode which leads
to SMP reboot failure.

Fix by reloading the mmu context on entering real mode.

Laurent Vivier ae6200baea KVM: x86 emulator: fix repne/repnz decoding
The repnz/repne instructions must set rep_prefix to 1 like rep/repe/repz.

This patch correct the disk probe problem met with OpenBSD.

This issue appears with commit e70669abd4
because before it, the decoding was done internally to kvm and after it
is done by x86_emulate.c (which doesn't do it correctly).

Olof Johansson 81429973cf [NIU]: Cleanup PAGE_SIZE checks a bit
I get the following warning from a powerpc allyesconfig of current
mainline:

drivers/net/niu.c: In function 'niu_size_rbr':
drivers/net/niu.c:3113: warning: large integer implicitly truncated to unsigned type

PAGE_SIZE in this case is 64KB, so I don't quite get why gcc can't
tell that the line in question will never be reached.

I suggest the following instead, but I can unfortunately not do
anything but build test it.

Also, the driver does some other checks to make sure that PAGE_SIZE is
a power of two (BUILD_BUG_ON() in niu_init()), doesn't seem like that
could ever be untrue? Or are there really archs with non-power-of-two
PAGE_SIZE?

Herbert Xu deea84b0ae [NET]: Fix SKB_WITH_OVERHEAD calculation
The calculation in SKB_WITH_OVERHEAD is incorrect in that it can cause
an overflow across a page boundary which is what it's meant to prevent.
In particular, the header length (X) should not be lumped together with
skb_shared_info.  The latter needs to be aligned properly while the header
has no choice but to sit in front of wherever the payload is.

Therefore the correct calculation is to take away the aligned size of
skb_shared_info, and then subtract the header length.  The resulting
quantity L satisfies the following inequality:

	SKB_DATA_ALIGN(L + X) + sizeof(struct skb_shared_info) <= PAGE_SIZE

This is the quantity used by alloc_skb to do the actual allocation.

Marcel Holtmann a9de924806 [Bluetooth] Switch from OGF+OCF to using only opcodes
The Bluetooth HCI commands are divided into logical OGF groups for
easier identification of their purposes. While this still makes sense
for the written specification, its makes the code only more complex
and harder to read. So instead of using separate OGF and OCF values
to identify the commands, use a common 16-bit opcode that combines
both values. As a side effect this also reduces the complexity of
OGF and OCF calculations during command header parsing.
