ARM: 9012/1: move device tree mapping out of linear region

2021-05-19T08:08:32+00:00

commit 7a1be318f5795cb66fa0dc86b3ace427fe68057f upstream

On ARM, setting up the linear region is tricky, given the constraints
around placement and alignment of the memblocks, and how the kernel
itself as well as the DT are placed in physical memory.

Let's simplify matters a bit, by moving the device tree mapping to the
top of the address space, right between the end of the vmalloc region
and the start of the the fixmap region, and create a read-only mapping
for it that is independent of the size of the linear region, and how it
is organized.

Since this region was formerly used as a guard region, which will now be
populated fully on LPAE builds by this read-only mapping (which will
still be able to function as a guard region for stray writes), bump the
start of the [underutilized] fixmap region by 512 KB as well, to ensure
that there is always a proper guard region here. Doing so still leaves
ample room for the fixmap space, even with NR_CPUS set to its maximum
value of 32.

Documentation/arm/samsung-s3c24xx: Remove stray U+FEFF character to fix title

2019-08-12T21:25:32+00:00

It seems a UTF-8 byte order mark (the least useful kind of BOM...) snuck
into the file and broke Sphinx's detection of the title line.

Besides making arm/samsung-s3c24xx/index.html look a little better, this
patch also confines the non-index pages in arm/samsung-s3c24xx to their
own table of contents.

docs: arm: convert docs to ReST and rename to *.rst

2019-07-15T12:20:24+00:00

Converts ARM the text files to ReST, preparing them to be an
architecture book.

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.
