lib/: replace HTTP links with HTTPS ones

2020-08-12T17:58:00+00:00

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

docs: move remaining stuff under Documentation/*.txt to Documentation/staging

2020-06-19T20:17:05+00:00

There are several files that I was unable to find a proper place
for them, and 3 ones that are still in plain old text format.

Let's place those stuff behind the carpet, as we'd like to keep the
root directory clean.

We can later discuss and move those into better places.

lib/xz: fix XZ_DYNALLOC to avoid useless memory reallocations

2019-11-16T02:34:00+00:00

s->dict.allocated was initialized to 0 but never set after a successful
allocation, thus the code always thought that the dictionary buffer has
to be reallocated.

lib/xz: Put CRC32_POLY_LE in xz_private.h

2018-10-01T22:44:59+00:00

This fixes a regression introduced by faa16bc404d72a5 ("lib: Use
existing define with polynomial").

The cleanup added a dependency on include/linux, which broke the PowerPC
boot wrapper/decompresser when KERNEL_XZ is enabled:

  BOOTCC  arch/powerpc/boot/decompress.o
 In file included from arch/powerpc/boot/../../../lib/decompress_unxz.c:233,
                 from arch/powerpc/boot/decompress.c:42:
 arch/powerpc/boot/../../../lib/xz/xz_crc32.c:18:10: fatal error:
 linux/crc32poly.h: No such file or directory
  #include 
           ^~~~~~~~~~~~~~~~~~~

The powerpc decompresser is a hairy corner of the kernel. Even while building
a 64-bit kernel it needs to build a 32-bit binary and therefore avoid including
files from include/linux.

This allows users of the xz library to avoid including headers from
'include/linux/' while still achieving the cleanup of the magic number.

lib/xz: Add fall-through comments to a switch statement

2017-10-12T13:10:12+00:00

It's good style. I was also told that GCC 7 is more strict and might
give a warning when such comments are missing.

lib/xz: enable all filters by default in Kconfig

2014-06-04T23:54:18+00:00

This restores the old behavior that existed before 2013-02-22, when
changes were made by 64dbfb444c150 ("decompressors: drop dependency on
CONFIG_EXPERT") and 5dc49c75a2 ("decompressors: make the default
XZ_DEC_* config match the selected architecture").

Disabling the filters only makes sense on embedded systems.

decompressors: fix typo "POWERPC"

2013-03-13T22:21:48+00:00

Commit 5dc49c75a26b ("decompressors: make the default XZ_DEC_* config
match the selected architecture") added

	default y if POWERPC

to lib/xz/Kconfig.  But there is no Kconfig symbol POWERPC.  The most
general Kconfig symbol for the powerpc architecture is PPC.  So let's
use that.
