PATCH: gcc 3.3 support and quota workaround

["H. J. Lu" <hjl@lucon.org>]

[-- Attachment #1: Type: text/plain, Size: 468 bytes --]

I am using gcc 3.3 to build the ia64 2.4 kernel from

http://lia64.bkbits.net/linux-ia64-2.4

Gcc 3.3 doesn't like multi-line asm statement. I am enclosing a patch
here.

Also the kernel won't compile with

CONFIG_QUOTA=y

in .config since INIT_QUOTA_MODULE_NAMES is not defined anywhere. I
looked at fs/dquot.c. There are some codes which weren't in 2.4.22-pre6
nor 2.4.22-pre7. Where did they come from? I use the patch enclosed to
get the kernel to compile.


H.J.
