Message-ID: <20070411123002.F17547@jurassic.park.msu.ru>
Date: Wed, 11 Apr 2007 12:30:02 +0400
From: Ivan Kokshaysky <ink@...assic.park.msu.ru>

Subject: [PATCH 5/7] ALPHA: fixes for specific machine types
Files:
arch/alpha/kernel/core_mcpcia.c
arch/alpha/kernel/sys_rawhide.c
include/asm-alpha/core_mcpcia.h
Determine correct hose configuration; RAWHIDE family can have
2 or 4 hoses, so make sure non-existent hoses are ignored.
arch/alpha/kernel/err_titan.c
Supply a needed #include <asm/irq_regs.h>
arch/alpha/kernel/module.c
Add some useful output to the relocation overflow messages.
arch/alpha/kernel/sys_noritake.c
Supply necessary noritake_end_irq() to correct interrupt handling.
This fixes a problem first noted by hangs during boot probing with
a DE500-BA TULIP NIC present.
arch/alpha/kernel/sys_sio.c
Correct saving of original PIRQ register (PCI IRQ routing);
change default PIRQ setting to leave PCI IRQs 9 and 14 free to
be used for sound (Multia) and IDE (any), respectively.
include/asm-alpha/io.h
Supply the "isa_virt_to_bus" routine.
