* [PATCH] i386/x86-64: Remove un/set_nmi_callback and ↵Don Zickus2006-09-26
| | | | | | | | | | | | | reserve/release_lapic_nmi functions Removes the un/set_nmi_callback and reserve/release_lapic_nmi functions as they are no longer needed. The various subsystems are modified to register with the die_notifier instead. Also includes compile fixes by Andrew Morton.

* [PATCH] Add TIF_RESTORE_SIGMASKAndi Kleen2006-09-26
| | | | | | | | | | We need TIF_RESTORE_SIGMASK in order to support ppoll() and pselect() system calls. This patch originally came from Andi, and was based heavily on David Howells' implementation of same on i386. I fixed a typo which was causing do_signal() to use the wrong signal mask.

* [PATCH] x86: Cleanup NMI interrupt pathDon Zickus2006-09-26
| | | | | | | | | | | This patch cleans up the NMI interrupt path. Instead of being gated by if the 'nmi callback' is set, the interrupt handler now calls everyone who is registered on the die_chain and additionally checks the nmi watchdog, reseting it if enabled. This allows more subsystems to hook into the NMI if they need to (without being block by set_nmi_callback). Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>
* [PATCH] i386: Add SMP support on i386 to reservation frameworkDon Zickus2006-09-26
| | | | | | | | | | | This patch includes the changes to make the nmi watchdog on i386 SMP aware. A bunch of code was moved around to make it simpler to read. In addition, it is now possible to determine if a particular NMI was the result of the watchdog or not. This feature allows the kernel to filter out unknown NMIs easier.

* [PATCH] x86: Add performance counter reservation framework for UP kernelsDon Zickus2006-09-26
| | | | | | | | | | | | | | | | | | Adds basic infrastructure to allow subsystems to reserve performance counters on the x86 chips. Only UP kernels are supported in this patch to make reviewing easier. The SMP portion makes a lot more changes. Think of this as a locking mechanism where each bit represents a different counter. In addition, each subsystem should also reserve an appropriate event selection register that will correspond to the performance counter it will be using (this is mainly neccessary for the Pentium 4 chips as they break the 1:1 relationship to performance counters). This will help prevent subsystems like oprofile from interfering with the nmi watchdog. Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>

* [PATCH] i386: Allow to use GENERICARCH for UP kernelsAndi Kleen2006-09-26
| | | | | | | | | | | | There are some machines around (large xSeries or Unisys ES7000) that need physical IO-APIC destination mode to access all of their IO devices. This currently doesn't work in UP kernels as used in distribution installers. This patch allows to compile even UP kernels as GENERICARCH which allows to use physical or clustered APIC mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some file systems want to manually d_move() the dentries involved in a rename. We can do this by making use of the FS_ODD_RENAME flag if we just have nfs_rename() unconditionally do the d_move(). While there, we rename the flag to be more descriptive. OCFS2 uses this to protect that part of the rename operation with a cluster lock.

Unfortunately at least one device seems to like doing this - the Gigabyte iRAM. This is only done for the master right now (which is fine for the iRAM as it is SATA), as with PATA some combinations of ATAPI device seem to fool the check into seeing a drive that isn't there if it is applied to the slave.

Only separate irq for the non-uniform secondary port was implemented while all other fields (host flags, transfer mode...) of the secondary port simply shared those of the first. For ata_piix combined mode, which ATM is the only user of non-uniform ports, this causes the secondary port assume the wrong type. This can cause PATA port to use SATA ops, which results in bogus check on PCS and detection failure. This patch adds ata_probe_ent->pinfo2 which points to optional port_info for the secondary port. For the time being, this seems to be the simplest solution. This workaround will be removed together with ata_probe_ent itself after init model is updated to allow more flexibility.

The dummy port is used as placeholder for stolen legacy port. This allows libata to guarantee that index_of(ap) == ap->port_no == actual_device_port_no, and thus to remove error-prone ap->hard_port_no. As it's used only when one port of a legacy controller is reserved by some other entity (e.g. IDE), the focus is on keeping the added *code* complexity at minimum, so dummy port allocates all libata core resources and acts as a normal port. It just has all dummy port_ops. This patch only implements dummy port. The following patch will make libata use it for stolen legacy ports. Signed-off-by: Tejun Heo <htejun@gmail.com>

Longer term Jeff also wants to move the request_irq/free_irq out of core which will make this even cleaner. tj: folded in three followup patches - ata_piix-fix, broken-arch-fix and fix-new-legacy-handling, and separated per-dev xfermask into separate patch preceding this one. Folded in fixes are... * ata_piix-fix: fix build failure due to host_set->next removal * broken-arch-fix: add missing include/asm-*/libata-portmap.h * fix-new-legacy-handling: * In ata_pci_init_legacy_port(), probe_num was incorrectly incremented during initialization of the secondary port and probe_ent->n_ports was incorrectly fixed to 1. * Both legacy ports ended up having the same hard_port_no. * When printing port information, both legacy ports printed the first irq.

It introduces some new APIs which allow libata to be used without allocating a virtual scsi host. New APIs: ata_sas_port_alloc - Allocate an ata_port ata_sas_port_init - Initialize an ata_port (probe device, etc) ata_sas_port_destroy - Free an ata_port allocated by ata_sas_port_alloc ata_sas_slave_configure - configure scsi device ata_sas_queuecmd - queue a scsi command, similar to ata_scsi_queuecomand These new APIs can be used either directly by a SAS LLDD or could be used by the SAS transport class. Possible usage for a SAS LLDD would be: scsi_scan_host target_alloc ata_sas_port_alloc slave_alloc ata_sas_port_init slave_configure ata_sas_slave_configure Commands received by the LLDD for SATA devices would call ata_sas_queuecmd. Device teardown would occur with: slave_destroy port_disable target_destroy ata_sas_port_destroy Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
