This version has some suggestions by Eric Dumazet:
- Use a local variable for the mark in IPv6 instead of ctl_sk to avoid SMP
races.
- Use the more elegant "IP4_REPLY_MARK(net, skb->mark) ?: sk->sk_mark"
statement.
- Factorize code as sk_fullsock() check is not necessary.

Now that GCC 8 is out, several people have complained about a bunch of
objtool warnings. These patches fix all known warnings.
Patch 1 is a repost of a previous fix -- unrelated to GCC 8, but a
prereq for the following two patches.
Patch 2 fixes the vast majority of the warnings, caused by GCC 8
Objtool has some crude logic for detecting static "noreturn" functions
(aka "dead ends"). This is necessary for being able to correctly follow
GCC code flow when such functions are called.
It's remotely possible for two functions to call each other via sibling
calls. If they don't have RET instr

Add some additional checks to the switch jump table logic. This fixes
the following warnings with GCC 8:

GCC 8 moves a lot of unlikely code out of line to "cold" subfunctions in
.text.unlikely. Properly detect the new subfunctions and treat them as
extensions of the original functions.
This fixes a bunch of warnings like:

For me, as a reader whose mother language isn't English, the
old words bring a little difficulty to catch the meaning, this
patch rewords the subsection in a more clarificatory way.

When to execute binder_stat_br the e->cmd has been modifying as BR_OK
instead of the original return error cmd, in fact we want to know the
original return error, such as BR_DEAD_REPLY or BR_FAILED_REPLY, etc.
instead of always BR_OK, in order to avoid the value of the e->cmd is

Some architectures just don't have PAGE_KERNEL_EXEC. The mm/nommu.c
and mm/vmalloc.c code have been using PAGE_KERNEL as a fallback for years.
Move this fallback to asm-generic.
Architectures which do not define PAGE_KERNEL_EXEC yet:
o alpha
o mips
o openrisc
o sparc64

While dusting out the firmware loader closet I spotted a PAGE_KERNEL_*
fallback hack. This hurts my eyes, and it should also be blinding
others. Turns out we have other PAGE_KERNEL_* fallback hacks in
other places.
This moves them to asm-generic, and keeps track of architectures which
need some lo
Some architectures do not define certain PAGE_KERNEL_* flags, this is
either because:
a) The way to implement some these flags is *not yet ported*, or
b) The architecture *has no way* to describe them
Over time we have accumulated a few PAGE_KERNEL_* fallback work arounds for
architectures in the
This allows bcm2835-camera to automatically probe after VCHI has
loaded, rather than only successfully probing if the arbitrary probe
order chooses us after VCHI.

We had the camera driver set up in a module_init function, but that
meant that the camera driver would fail to load if it was initialized
before VCHI. This enforces that it loads after we've successfully set
up.

Would there be enough potential callers in future to justify that API?
