      docs: kdump: convert docs to ReST and rename to *.rst · d67297ad
      Mauro Carvalho Chehab authored 
      
Convert kdump documentation to ReST and add it to the
user faced manual, as the documents are mainly focused on
sysadmins that would be enabling kdump.

Note: the vmcoreinfo.rst has one very long title on one of its
sub-sections:

	PG_lru|PG_private|PG_swapcache|PG_swapbacked|PG_slab|PG_hwpoision|PG_head_mask|PAGE_BUDDY_MAPCOUNT_VALUE(~PG_buddy)|PAGE_OFFLINE_MAPCOUNT_VALUE(~PG_offline)

I opted to break this one, into two entries with the same content,
in order to make it easier to display after being parsed in html and PDF.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

      ARM: riscpc: replace gettimeoffset() with clocksource · a44c1d70
      Russell King authored 
      
Replace the old gettimeoffset() interface (which became buggy in
several ways) with a clocksource that atomically reads the count
and status from the timer, and corrects the count as appropriate
ensuring proper resolution of time without time warping backwards.

We keep the original periodic timer non-clock event implementation
to provide the kernel with a regular source of interrupts, which
are required to keep the clocksource properly updated.

      ARM: ixp4xx: Convert to SPARSE_IRQ · dc8ef8cd
      Linus Walleij authored 
      
This localizes the <mach/irqs.h> header to the mach-ixp4xx
directory, removes NR_IRQS and switches IXP4xx over to using
SPARSE_IRQ.

This is a prerequisite for DT support.

      ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER · 98ac0cc2
      Linus Walleij authored 
      
This rewrites the IXP4xx to use MULTI_IRQ_HANDLER and
create an irqdomain for the irqchip in the platform. We
convert the timer to request the interrupt like any other
driver in the process.

We bump all IRQs to 16+offset to avoid using IRQ 0 and
set NR_IRQS to 512 (the default for most systems).
This conveniently fits with the first 16 IRQs being
pre-allocated when using SPARSE_IRQ.

This is a prerequisite for SPARSE_IRQ and DT boot.

      locking/rwsem: Remove rwsem-spinlock.c & use rwsem-xadd.c for all archs · 390a0c62
      Waiman Long authored 
      
Currently, we have two different implementation of rwsem:

 1) CONFIG_RWSEM_GENERIC_SPINLOCK (rwsem-spinlock.c)
 2) CONFIG_RWSEM_XCHGADD_ALGORITHM (rwsem-xadd.c)

As we are going to use a single generic implementation for rwsem-xadd.c
and no architecture-specific code will be needed, there is no point
in keeping two different implementations of rwsem. In most cases, the
performance of rwsem-spinlock.c will be worse. It also doesn't get all
the performance tuning and optimizations that had been implemented in
rwsem-xadd.c over the years.

For simplication, we are going to remove rwsem-spinlock.c and make all
architectures use a single implementation of rwsem - rwsem-xadd.c.

All references to RWSEM_GENERIC_SPINLOCK and RWSEM_XCHGADD_ALGORITHM
in the code are removed.
