Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies(). As the value here is a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication.
This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with
the following Coccinelle rules:
@@ constant C; @@
- msecs_to_jiffies(C * 1000)
+ secs_to_jiffies(C)
@@ constant C; @@
- msecs_to_jiffies(C * MSEC_PER_SEC)
+ secs_to_jiffies(C)

The "leak" pointer, in the sample of shadow variable API, is allocated
as sizeof(int). Let's help developers and static analyzers with
understanding the code by using the appropriate pointer type.

Sparse reported warnings about non-static symbols. For the variables
a simple static attribute is fine - for the functions referenced by
livepatch via klp_func the symbol-names must be unmodified in the
symbol table and the patchable code has to be emitted. The resolution
is to attach __used attribute to the shared statically declared functions.

kzalloc() return should always be checked - notably in example code
where this may be seen as reference. On failure of allocation in
livepatch_fix1_dummy_alloc() respectively dummy_alloc() previous
allocation is freed (thanks to Petr Mladek <pmladek@suse.com> for
catching this) and NULL returned.

Add exported API for livepatch modules:
klp_shadow_get()
klp_shadow_alloc()
klp_shadow_get_or_alloc()
klp_shadow_free()
klp_shadow_free_all()
that implement "shadow" variables, which allow callers to associate new
shadow fields to existing data structures. This is intended to be used
by livepatch modules seeking to emulate additions to data structure
definitions.
See Documentation/livepatch/shadow-vars.txt for a summary of the new
shadow variable API, including a few common use cases.
See samples/livepatch/livepatch-shadow-* for example modules that
demonstrate shadow variables.
