Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Pull sparc updates from Andreas Larsson:

 - Align sparc to other archs by providing ucontext.h wrapper

 - Fix buffer underflow in led driver

 - Export mcount for clang and disable compat when using lld for linking

 - API choice improvement for sysfs code for vio

 - Fix build warnings and notification of missing prototype

 - Remove dead code and dead configs

* tag 'sparc-for-7.2-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/alarsson/linux-sparc:
  sparc: Remove remaining defconfig references to the pktcdvd driver
  sparc: led: avoid trimming a newline from empty writes

  sparc32: remove deadwood swift_flush_tlb_page() debug code
  sparc: uapi: Add ucontext.h
  sparc: vio: use sysfs_emit in sysfs show functions

led_proc_write() duplicates up to LED_MAX_LENGTH bytes with
memdup_user_nul() and then unconditionally inspects buf[count - 1] to
strip a trailing newline. A zero-length write therefore reads one byte
before the duplicated buffer.

The previous version rejected empty writes, but empty input already falls
through to the existing default case and turns the LED off like any other
unrecognized string. Preserve that behavior and only skip the newline
trim when there is no input byte to inspect.

Quite some architectures have four character wide acronyms for architecture
specific interrupts like IPI, NMI, etc.

The default precision of printing the Linux device interrupt numbers is
three, which causes quite some code to play games with adding or omitting
space after the acronym and the colon in order to keep the per CPU numbers
properly aligned.

Increase the default number precision to four in the core code and get rid
of the space games all over the place. At the same time align all
architecture specific descriptor texts left so that they show up in the
same column as the interrupt chip names, which makes the output more
uniform accross architectures. Fix up the GDB script to this new scheme as
well.
