  asm-generic: mark __{get,put}_user_fn as __always_inline

Under some circumstances, the compiler generates .ctors.* sections. This
is seen doing a cross compile of x86_64 from a powerpc64el host:

x86_64-linux-gnu-ld: warning: orphan section `.ctors.65435' from `kernel/trace/trace_clock.o' being
placed in section `.ctors.65435'
x86_64-linux-gnu-ld: warning: orphan section `.ctors.65435' from `kernel/trace/ftrace.o' being
placed in section `.ctors.65435'
x86_64-linux-gnu-ld: warning: orphan section `.ctors.65435' from `kernel/trace/ring_buffer.o' being
placed in section `.ctors.65435'

Include these orphans along with the regular .ctors section.

Without the explicit __always_inline, some RISC-V configs place the
functions out of line, triggering the BUILD_BUG_ON checks in the
function.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

Conversion done using the script at:

Pull more Kunit updates from Shuah Khan:

 - add Kunit to kernel_init() and remove KUnit from init calls entirely.

   This addresses the concern that Kunit would not work correctly during
   late init phase.

 - add a linker section where KUnit can put references to its test
   suites.

   This is the first step in transitioning to dispatching all KUnit
   tests from a centralized executor rather than having each as its own
   separate late_initcall.

 - add a centralized executor to dispatch tests rather than relying on
   late_initcall to schedule each test suite separately. Centralized
   execution is for built-in tests only; modules will execute tests when
   loaded.

 - convert bitfield test to use KUnit framework

   kunit_test_suite() works.
