2015-03-05genirq: Remove the deprecated 'IRQF_DISABLED' request_irq() flag entirelyValentin Rothberg1-6/+4
The IRQF_DISABLED flag is a NOOP and has been scheduled for removal since Linux v2.6.36 by commit 6932bf37bed4 ("genirq: Remove IRQF_DISABLED from core code"). According to commit e58aa3d2d0cc ("genirq: Run irq handlers with interrupts disabled"), running IRQ handlers with interrupts enabled can cause stack overflows when the interrupt line of the issuing device is still active. This patch ends the grace period for IRQF_DISABLED (i.e., SA_INTERRUPT in older versions of Linux) and removes the definition and all remaining usages of this flag. There's still a few non-functional references left in the kernel source: - The bigger hunk in Documentation/scsi/ncr53c8xx.txt is removed entirely as IRQF_DISABLED is gone now; the usage in older kernel versions (including the old SA_INTERRUPT flag) should be discouraged. The trouble of using IRQF_SHARED is a general problem and not specific to any driver. - I left the reference in Documentation/PCI/MSI-HOWTO.txt untouched since it has already been removed in linux-next. - All remaining references are changelogs that I suggest to keep.

2014-11-05ARM: OMAP3: Fix errors for omap_l3_smx when booted with device treeTony Lindgren1-5/+21
When booting omap3 in device tree mode, we're currently getting the following errors: omap_l3_smx omap_l3_smx.0: couldn't request debug irq omap_l3_smx: probe of omap_l3_smx.0 failed with error -22 This is because we don't have handling in the driver for the compatible property and instead assume platform data being passed. Note that this binding is already documented, and implemented for the related omap_l3_noc driver for omap4 and later. Looks like the binding somehow never got never implemented for this omap_l3_smx driver though. Let's also remove __exit_p to allow binding and unbinding of the driver while at it.

2012-09-19drivers: bus: Move the OMAP interconnect driver to drivers/bus/Santosh Shilimkar1-0/+297
OMAP interconnect drivers are used for the interconnect error handling. Since they are bus driver, lets move it to newly created drivers/bus.
