This adds the driver for the Briq front panel. This is a cleaned up version of a driver that has been floating around for some time now, initially written by Karsten Jeppesen <karsten@jeppesens.com> and cleaned up by jk and myself.

The support for Briq machines has been floating around as patches for ages. This cleans it up and adds it once for all. Some of this is based on initial code provided by Karsten Jeppesen <karsten@jeppesens.com> and mostly rewritten from scratch by me.

The code in legacy_serial.c wouldn't properly compare OF translation results against OF_BAD_ADDR as it's using a phys_addr_t which is 32 bits on some 32-bit powerpc platforms. This fixes it by always using a u64 which is what is returned by the OF parsing routines. It also makes translation failure harmless for ISA serial ports. If they can't translate, we can't use the UART early, but we can still let the 8250 driver use it later on by using IO port accessors.

Pseudo-CHRP machines like Pegasos without an MPIC would crash at boot if CONFIG_SMP was set because the "smp_ops" pointer was set to MPIC related ops unconditionally. This patch makes it NULL on machines that don't support SMP and provides proper default behaviour in the callers when smp_ops is NULL.

The Pegasos firmware doesn't create a valid "ranges" property for the ISA bridge, thus causing translation of ISA addresses and IO ports to fail. This fixes it, thus re-enabling proper early serial console to work on Pegasos. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

I got some undefined references to __stack_chk_fail in arch/powerpc/boot/stdio.o and arch/powerpc/boot/prom.o when I was trying to build a kernel on Ubuntu Edgy Eft - which includes Stack Smashing Protection. This patch adds -fno-stack-protector to BOOTCFLAGS in arch/powerpc/boot/Makefile (why does BOOTCFLAGS depend on HOSTCFLAGS and not CFLAGS?).

"return -err" and blindly inheriting the error code in the netlink failure exception handler causes errors codes to be returned as positive value therefore making them being ignored by the caller.

The TCA_ACT_KIND attribute is used without checking its availability when dumping actions therefore leading to a value of 0x4 being dereferenced. The use of strcmp() in tc_lookup_action_n() isn't safe when fed with string from an attribute without enforcing proper NUL termination. Both bugs can be triggered with malformed netlink message and don't require any privileges. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

The sparc64 kernel's EXPORT_SYMBOL(_mcount) is inside an #ifdef CONFIG_SMP. This breaks modules in non-SMP kernels built with stack overflow checking (CONFIG_STACK_DEBUG=y), as modules_install reports: WARNING: /lib/modules/2.6.17/kernel/drivers/ide/ide-cd.ko needs unknown symbol _mcount Trivially fixed by moving EXPORT_SYMBOL(_mcount) outside of the #ifdef CONFIG_SMP.

Reimplement controller-wide PM. ata_host_set_suspend/resume() are defined to suspend and resume a host_set. While suspended, EHs for all ports in the host_set are pegged using ATA_FLAG_SUSPENDED and frozen. Because SCSI device hotplug is done asynchronously against the rest of libata EH and the same mutex is used when adding new device, suspend cannot wait for hotplug to complete. So, if SCSI device hotplug is in progress, suspend fails with -EBUSY. In most cases, host_set resume is followed by device resume. As each resume operation requires a reset, a single host_set-wide resume operation may result in multiple resets. To avoid this, resume waits upto 1 second giving PM to request resume for devices.

Reimplement per-dev PM. The original implementation directly put the device into suspended mode and didn't synchronize w/ EH operations including hotplug. This patch reimplements ata_scsi_device_suspend() and ata_scsi_device_resume() such that they request EH to perform the respective operations. Both functions synchronize with hotplug such that it doesn't operate on detached devices. Suspend waits for completion but resume just issues request and returns. This allows parallel wake up of devices and thus speeds up system resume. Due to sdev detach synchronization, it's not feasible to separate out EH requesting from sdev handling; thus, ata_device_suspend/resume() are removed and everything is implemented in the respective libata-scsi functions.

Tejun Heo authored
Implement two PM per-dev EH actions - ATA_EH_SUSPEND and ATA_EH_RESUME. Each action puts the target device into suspended mode and resumes from it respectively. Once a device is put to suspended mode, no EH operations other than RESUME is allowed on the device. The device will stay suspended till it gets resumed and thus reset and revalidated. To implement this, a new device state helper - ata_dev_ready() - is implemented and used in EH action implementations to make them operate only on attached & running devices. If all possible devices on a port are suspended, reset is skipped too. This prevents spurious events including hotplug events from disrupting suspended devices.

Implement ATA_EHI_NO_AUTOPSY and QUIET. These used to be implied by ATA_PFLAG_LOADING, but new power management and PMP support need to use these separately. e.g. Suspend/resume operations shouldn't print full EH messages and resume shouldn't be recorded as an error.

The names of predefined debounce timing parameters didn't exactly match their usages. Rename to more generic names and implement param selection helper sata_ehc_deb_timing() which uses EHI_HOTPLUGGED to select params. Combined with the previous EHI_RESUME_LINK differentiation, this makes parameter selection accurate. e.g. user scan resumes link but normal deb param is used instead of hotplug param.

Implement ATA_EHI_RESUME_LINK, which indicates that the link needs to be resumed. This used to be implied by ATA_EHI_HOTPLUGGED. However, hotplug isn't the only event which requires link resume and separating this out allows other places to request link resume. This differentiation also allows better debounce timing selection. This patch converts user scan to use ATA_EHI_RESUME_LINK. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

ap_lock was used because &ap->host_set->lock was too long and used a lot. Now that &ap->host_set->lock is replaced with ap->lock, there's no reason to keep ap_lock. [ed. note: that's not entirely true. ap_lock is a local variable, caching the results of a de-ref. In theory, if the compiler is smart enough, this patch is cosmetic. However, since this is not a fast path (it is the error path), this patch is nonetheless acceptable, even though it _may_ introduce a performance regression.] Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

ap->flags is way too clamped. Separate out core dynamic flags to ap->pflags.
