Subject: [PARISC] Fix CONFIG_DEBUG_SPINLOCK
X-Git-Tag: v2.6.19-rc1~34^2~6
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d207ac0f7c9736782bfa51cff2109b74d26c3622;p=linux-2.6

[PARISC] Fix CONFIG_DEBUG_SPINLOCK

Joel Soete points out that we refer to pa_tlb_lock but only define it if
CONFIG_SMP which breaks a uniprocessor build with CONFIG_DEBUG_SPINLOCK
enabled.  No module refers to pa_tlb_lock, so we can delete the export.
