2013-11-11powerpc: add missing explicit OF includes for ppcRob Herring
Commit b5b4bb3f6a11f9 (of: only include prom.h on sparc) removed implicit includes of of_*.h headers by powerpc's prom.h. Some components were missed in initial clean-up patch, so add the necessary includes to fix powerpc builds.

2012-02-16irq_domain: Replace irq_alloc_host() with revmap-specific initializersGrant Likely
Each revmap type has different arguments for setting up the revmap. This patch splits up the generator functions so that each revmap type can do its own setup and the user doesn't need to keep track of how each revmap type handles the arguments. This patch also adds a host_data argument to the generators. There are cases where the host_data pointer will be needed before the function returns. ie. the legacy map calls the .map callback for each irq before returning. v2: - Add void *host_data argument to irq_domain_add_*() functions - fixed failure to compile - Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: Olof Johansson <olof@lixom.net>
2012-02-14irq_domain/powerpc: Use common irq_domain structure instead of irq_hostGrant Likely
This patch drops the powerpc-specific irq_host structures and uses the common irq_domain strucutres defined in linux/irqdomain.h. It also fixes all the users to use the new structure names. Renaming irq_host to irq_domain has been discussed for a long time, and this patch is a step in the process of generalizing the powerpc virq code to be usable by all architecture. An astute reader will notice that this patch actually removes the irq_host structure instead of renaming it. This is because the irq_domain structure already exists in include/linux/irqdomain.h and has the needed data members.

2011-11-24arch/powerpc/sysdev/ehv_pic.c: add missing kfreeJulia Lawall
At this point, ehv_pic has been allocated but not stored anywhere, so it should be freed before leaving the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ local idexpression x; statement S,S1; expression E; identifier fl; expression *ptr != NULL; @@ x = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...kfree(x)...+> } when any when != true x == NULL x->fl ...> ( if (x == NULL) S1 | if (...) { ... when != x when forall ( return \(0\|<+...x...+>\|ptr\); | * return ...; ) } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-06-27powerpc: introduce the ePAPR embedded hypervisor vmpic driverAshish Kalra
The Freescale ePAPR reference hypervisor provides interrupt controller services via a hypercall interface, instead of emulating the MPIC controller. This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.
