Subject: Set noinline on kbd.c interface functions that take stack variable pointers.
X-Git-Tag: rel-1.7.1~44
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=8ab4a7de12a2fc776822c82cc4233a37b35c40f3;p=seabios.git

Set noinline on kbd.c interface functions that take stack variable pointers.

Some versions of gcc have been found to inline these funcions and then
cause the calling functions to use very large stack usage.  Since
these functions are called from 16bit mode, their stack space usage is
very sensitive.
