[PATCH 1/2] PCI/MSI: Allow an msi_chip to be associated to an irq domain

With the new stacked irq domains, it becomes pretty tempting to allocate an MSI domain per PCI bus, which would remove the requirement of either relying on arch-specific code, or a default PCI MSI domain. By allowing the msi_chip structure to carry a pointer to an irq_domain, we can easily use thi

[PATCH 1/1] lib/mpi: Deletion of unnecessary checks before the function call "mpi_free_limb_space"

From: Markus Elfring Date: Sat, 15 Nov 2014 21:33:26 +0100 The mpi_free_limb_space() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring --

[PATCH V2 00/22] Multiplatform BMIPS kernel

This patch series implements a multiplatform target that runs on a variety of different Broadcom chipsets based on the BMIPS CPUs. It evolved out of the "BMIPS updates and BCM3384 platform support" RFC posted earlier. V1->V2: - Add several more DTS files so the same kernel can boot on multiple

[PATCH V2 04/22] irqchip: bcm7120-l2: Refactor driver for arbitrary IRQEN/IRQSTAT offsets

Currently the driver assumes that REG_BASE+0x00 is the IRQ enable mask, and REG_BASE+0x04 is the IRQ status mask. This is true on BCM3384 and BCM7xxx, but it is not true for some of the controllers found on BCM63xx chips. So we will change a couple of key assumptions: - Don't assume that both t
