[PATCH] 2.4.19 warnings cleanup

[Krzysztof Halasa <khc@pm.waw.pl>]

[-- Attachment #1: Type: text/plain, Size: 320 bytes --]

Hi,

The attached patch eliminates some compiler warning messages from
various parts of the kernel. It disables some unused code (compressed
ramdisk routines if no ramdisk support). Shouldn't break anything,
but I wouldn't rather apply it in final rc-* stages...

2.4.19 only.
