Hi,
AIX contains the SIGDANGER signal to notify applications to free up some
unused cached memory:

There have been a few discussions on implementing such an idea on Linux,
but nothing concrete has been achieved.

movntq instruction is supported by Geode CPU's, so use
fast_clear_page/fast_copy_page versions that have it.

Hi,
The following patch adds a config option to get rid of the DMA zone on i386.
Architectures with devices that have no addressing limitations (eg. PPC)
already work this way.
This is useful for custom kernel builds where the developer is certain that
there are no address limitations.
For exa

Please fix identation accordingly to CodingStyle and repost, it
looks quite ugly at the moment.

Hi,
Here goes the 8xx PCMCIA driver, originally written by Magnus Damm, with
several improvements and fixes.
The driver was merged in v2.4 but never forward ported to v2.6.
Please review, comments are welcome (including aesthetic enhancements).
Russell: The driver is using pccard_nonstatic_ops
