Introduce CONFIG_CHECK_SIGNATURE

2007-08-23T02:52:45+00:00

Introduce CONFIG_CHECK_SIGNATURE to control inclusion of check_signature()
and avoid problems on platforms that don't have readb().

Let the few legacy (ISA || PCI || X86) drivers that need check_signature()
select CONFIG_CHECK_SIGNATURE.

Add LZO1X algorithm to the kernel

2007-07-11T00:51:13+00:00

This is a hybrid version of the patch to add the LZO1X compression
algorithm to the kernel.  Nitin and myself have merged the best parts of
the various patches to form this version which we're both happy with (and
are jointly signing off).

The performance of this version is equivalent to the original minilzo code
it was based on.  Bytecode comparisons have also been made on ARM, i386 and
x86_64 with favourable results.

There are several users of LZO lined up including jffs2, crypto and reiser4
since its much faster than zlib.

CRC ITU-T V.41

2007-05-10T16:24:13+00:00

This will add the CRC calculation according
to the CRC ITU-T V.41 to the kernel lib/ folder.

This code has been derived from the rt2x00 driver,
currently found only in the wireless-dev tree, but
this library is generic and could be used by more
drivers who currently use their own implementation.

Also useful for the new firewire stack.

Introduce CONFIG_HAS_DMA

2007-05-07T19:12:51+00:00

Architectures that don't support DMA can say so by adding a config NO_DMA
to their Kconfig file.  This will prevent compilation of some dma specific
driver code.  Also dma-mapping-broken.h isn't needed anymore on at least
s390.  This avoids compilation and linking of otherwise dead/broken code.

Other architectures that include dma-mapping-broken.h are arm26, h8300,
m68k, m68knommu and v850.  If these could be converted as well we could get
rid of the header file.

[PATCH] sort the devres mess out

2007-02-11T19:18:07+00:00

* Split the implementation-agnostic stuff in separate files.
* Make sure that targets using non-default request_irq() pull
  kernel/irq/devres.o
* Introduce new symbols (HAS_IOPORT and HAS_IOMEM) defaulting to positive;
  allow architectures to turn them off (we needed these symbols anyway for
  dependencies of quite a few drivers).
* protect the ioport-related parts of lib/devres.o with CONFIG_HAS_IOPORT.

[PATCH] bit reverse library

2006-12-08T16:28:39+00:00

This patch provides two bit reverse functions and bit reverse table.

- reverse the order of bits in a u32 value

	u8 bitrev8(u8 x);

- reverse the order of bits in a u32 value

	u32 bitrev32(u32 x);

- byte reverse table

	const u8 byte_rev_table[256];
