IRQF_SHARED appeared in Linux 2.6.18. Define it in compat.h for older kernels. Stop using obsolete SA_SHIRQ in if_ath_ahb.c and if_ath_pci.c This fixes compilation of if_ath_ahb.c for Linux 2.6.22 and newer. git-svn-id: http://madwifi-project.org/svn/madwifi/trunk@3041 0192ed92-7a03-0410-a25b-9323aeb14dbd
