Petrongonas fixes a panic which was happening with the combination of
EFI and KHO

Lougher teaches squashfs's lseek() about SEEK_DATA/SEEK_HOLE. A mere
150x speedup was measured for a well-chosen microbenchmark
- plus another 50-odd singleton patches all over the place

...
Add a new Coccinelle script to identify places where PTR_ERR() is used
in print functions and suggest using the %pe format specifier instead.
For printing error pointers (i.e., a pointer for which IS_ERR() is true)
%pe will print a symbolic error name (e.g,. -EINVAL), opposed to the raw
errno (e.g,. -22) produced by PTR_ERR().
It also makes the code cleaner by saving a redundant call to PTR_ERR().
The script supports context, report, and org modes.
Example transformation:
printk("Error: %ld\n", PTR_ERR(ptr)); // Before
printk("Error: %pe\n", ptr); // After

Since commit cdd30ebb1b ("module: Convert symbol namespace to string
literal"), when MODULE_IMPORT_NS() is missing, 'make nsdeps' inserts
pointless code:
MODULE_IMPORT_NS("ns");
Here, "ns" is not a namespace, but the variable in the semantic patch.
It must not be quoted. Instead, a string literal must be passed to
Coccinelle.

The isomorphism neg_if_exp negates the test of a ?: conditional,
making it unnecessary to have an explicit case for a negated test
with the branches inverted.
At the same time, we can disable neg_if_exp in cases where a
different API function may be more suitable for a negated test.
Finally, in the non-patch cases, E matches an expression with
parentheses around it, so there is no need to mention ()
explicitly in the pattern. The () are still needed in the patch
cases, because we want to drop them, if they are present.

The parentheses are only needed if there is a disjunction, ie a
set of possible changes. If there is only one pattern, we can
remove these parentheses. Just like the format:
- x
+ y
not:
(
- x
+ y
)
