2016-09-19NFSv4.x: Add kernel parameter to control the callback serverTrond Myklebust1-0/+12
Add support for the kernel parameter nfs.callback_nr_threads to set the number of threads that will be assigned to the callback channel. Add support for the kernel parameter nfs.nfs.max_session_cb_slots to set the maximum size of the callback channel slot table.

2016-08-29powerpc: signals: Discard transaction state from signal framesCyril Bur1-0/+2
Userspace can begin and suspend a transaction within the signal handler which means they might enter sys_rt_sigreturn() with the processor in suspended state. sys_rt_sigreturn() wants to restore process context (which may have been in a transaction before signal delivery). To do this it must restore TM SPRS. To achieve this, any transaction initiated within the signal frame must be discarded in order to be able to restore TM SPRs as TM SPRs can only be manipulated non-transactionally.. >From the PowerPC ISA: TM Bad Thing Exception [Category: Transactional Memory] An attempt is made to execute a mtspr targeting a TM register in other than Non-transactional state.

2016-08-17bus: arm-ccn: Correct required arguments for XP PMU eventsPawel Moll1-6/+10
XP can provide events from two sources: watchpoints, observing traffic on device ports and PMU looking at internal buses. Unfortunately the sysfs definition of the PMU events was requiring port number (instead of bus number) and direction (the buses are unidirectional), as these fields were shared with the watchpoint event. Although it does not introduce a major problem (port can be used as bus alias and direction is simply ignored for XP PMU events), it's better to fix it now, before external tools start depending on this behaviour.

2016-08-16PCI: Use positive flags in pci_alloc_irq_vectors()Christoph Hellwig1-14/+10
Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of certain interrupt types, pass positive flags like PCI_IRQ_LEGACY, PCI_IRQ_MSI, etc., to specify the acceptable interrupt types. This is based on a number of pending driver conversions that just happend to be a whole more obvious to read this way, and given that we have no users in the tree yet it can still easily be done. I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting all interrupt types very simple.

2016-08-09PCI: Update "pci=resource_alignment" documentationMathias Koehrer1-0/+4
Some uio based PCI drivers, e.g., uio_cif, do not work if the assigned PCI memory resources are not page aligned. By using the kernel option "pci=resource_alignment=<align>@<bus>:<slot>.<func>" it is possible to request page alignment for memory resources of devices. However, this is cumbersome when using several devices, and the bus/slot/func addresses may change if devices are added to or removed from the system. Extend the "pci=resource_alignment" option so we can specify the relevant devices via PCI vendor, device, subvendor, and subdevice IDs. The specification of the devices via IDs is indicated by a leading string "pci:" as argument to "pci=resource_alignment". The format of the specification is pci:<vendor>:<device>[:<subvendor>:<subdevice>] Examples: pci=resource_alignment=4096@pci:8086:9c22:103c:198f pci=resource_alignment=pci:8086:9c22 # defaults to PAGE_SIZE align [bhelgaas: changelog, use actual vendor/device IDs in examples] Signed-off-by: Mathias Koehrer <mathias.koehrer@etas.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

This means that old code that relies on manually setting bi_rw is most likely going to be broken.
