From: Al Viro
Date: Sun Oct 08 2006 - 09:45:04 EST

Next message: Al Viro: "[PATCH 4/4] alpha pt_regs cleanups: collapse set_irq_regs() in titan_dispatch_irqs()"
Previous message: Stas Sergeev: "Re: [patch] honour MNT_NOEXEC for access()"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

do set_irq_regs() in caller, kill pt_regs argument.
