From aa8f0dc6c3dbf1cf3ff58f3e945c981be134814d Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Thu, 26 May 2005 21:54:27 -0400 Subject: libata: Fix use-after-iounmap Jens Axboe pointed out that the iounmap() call in libata was occurring too early, and some drivers (ahci, probably others) were using ioremap'd memory after it had been unmapped. The patch should address that problem by way of improving the libata driver API: * move ->host_stop() call after all ->port_stop() calls have occurred. * create default helper function ata_host_stop(), and move iounmap() call there. * add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark). sata_qstor appears to require the host-stop-before-port-stop ordering that existed prior to applying the attached patch. --- include/linux/libata.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/linux') diff --git a/include/linux/libata.h b/include/linux/libata.h index 1f7e2039a04e..e74f301e9bae 100644 --- a/include/linux/libata.h +++ b/include/linux/libata.h @@ -410,6 +410,7 @@ extern u8 ata_chk_err(struct ata_port *ap); extern void ata_exec_command(struct ata_port *ap, struct ata_taskfile *tf); extern int ata_port_start (struct ata_port *ap); extern void ata_port_stop (struct ata_port *ap); +extern void ata_host_stop (struct ata_host_set *host_set); extern irqreturn_t ata_interrupt (int irq, void *dev_instance, struct pt_regs *regs); extern void ata_qc_prep(struct ata_queued_cmd *qc); extern int ata_qc_issue_prot(struct ata_queued_cmd *qc); -- cgit v1.2.3-71-gd317 From 668d1e6093110f7534e661e2ff43d54c74659b6d Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Sat, 28 May 2005 02:11:12 -0500 Subject: Input: This patch adds dummy gameport_register_port, gameport_unregister_port and gameport_set_phys functions to gameport.h for the case when a driver can't use gameport. This fixes the compilation of some OSS drivers with GAMEPORT=n without the need to #if inside every single driver. This patch also removes the non-working and now obsolete SOUND_GAMEPORT. This patch is also an alternative solution for ALSA drivers with similar problems (but #if's inside the drivers might have the advantage of saving some more bytes of gameport is not available). The only user-visible change is that for GAMEPORT=m the affected OSS drivers are now allowed to be built statically (but they won't have gameport support).
