From: Samuel Bronson Date: Thu, 7 May 2009 02:27:55 +0000 (-0400) Subject: x86: use symbolic name for VM86_SIGNAL when used as vm86 default return X-Git-Tag: v2.6.31-rc1~418^2~11 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=975e5f45500dff6d15c0001bb662e9aac0ce0076;p=karo-tx-linux.git x86: use symbolic name for VM86_SIGNAL when used as vm86 default return This code has apparently used "0" and not VM86_SIGNAL since Linux 1.1.9, when Linus added VM86_SIGNAL to vm86.h. This patch changes the code to use the symbolic name. The magic 0 tripped me up in trying to extend the vm86(2) manpage to actually explain vm86()'s interface -- my greps for VM86_SIGNAL came up fruitless.
