Subject: [PARISC] timer interrupt should not be IRQ_DISABLED
X-Git-Tag: v2.6.24-rc5~58^2~3
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2421ba5b57ddbc3a972b9d6fb884817c39d2fff7;p=linux-2.6

[PARISC] timer interrupt should not be IRQ_DISABLED

The timer interrupt had accidentally been marked IRQ_DISABLED since
IRQ_PER_CPU had been OR-ed in, instead of set. This had been working
by accident for quite a while.

Commit c642b8391cf8efc3622cc97329a0f46e7cbb70b8 changed the behaviour of
IRQ_PER_CPU interrupts, which previously weren't checked for IRQ_DISABLED.
