Subject: [IA64] operator priority fix in acpi_map_lsapic()
X-Git-Tag: v2.6.24-rc5~18^2~2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=965d747264c91ed206846d74ae09f757a36a373b;p=linux-2.6

[IA64] operator priority fix in acpi_map_lsapic()

'!' has a higher priority than '&', so as was
this won't test the first bit, but rather evaluates to false for any non-zero
lsapic->lapic_flags.
