2011-10-21iommu/omap: Use bus_set_iommu instead of register_iommuJoerg Roedel

2011-10-21iommu/core: Use bus->iommu_ops in the iommu-apiJoerg Roedel
Use the per-bus iommu-ops in the functions of the iommu-api instead of the global iommu_ops. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-10-21iommu/core: Convert iommu_found to iommu_presentJoerg Roedel
With per-bus iommu_ops the iommu_found function needs to work on a bus_type too. This patch adds a bus_type parameter to that function and converts all call-places. The function is also renamed to iommu_present because the function now checks if an iommu is present for a given bus and does not check for a global iommu anymore. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-10-21iommu/core: Add bus_type parameter to iommu_domain_allocJoerg Roedel
This is necessary to store a pointer to the bus-specific iommu_ops in the iommu-domain structure. It will be used later to call into bus-specific iommu-ops. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-10-21Driver core: Add iommu_ops to bus_typeJoerg Roedel
This is the starting point to make the iommu_ops used for the iommu-api a per-bus-type structure. It is required to easily implement bus-specific setup in the iommu-layer. The first user will be the iommu-group attribute in sysfs. Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

2011-09-05iommu/omap-iovmm: support non page-aligned buffers in iommu_vmapLaurent Pinchart
omap_iovmm requires page-aligned buffers, and that sometimes causes omap3isp failures (i.e. whenever the buffer passed from userspace is not page-aligned). Remove this limitation by rounding the address of the first page entry down, and adding the offset back to the device address.

2011-08-26sfi: table irq 0xFF means 'no interrupt'Kirill A. Shutemov
According to the SFI specification irq number 0xFF means device has no interrupt or interrupt attached via GPIO. Currently, we don't handle this special case and set irq field in *_board_info structs to 255. It leads to confusion in some drivers. Accelerometer driver tries to register interrupt 255, fails and prints "Cannot get IRQ" to dmesg. Signed-off-by: Kirill A.

2011-08-26omap: iommu: remove unused exported APIOhad Ben-Cohen
Remove unused public APIs from OMAP's iommu driver. IOMMU functionality should be exposed only via the generic IOMMU API; this way drivers stay generic, and different IOMMU drivers don't need to duplicate similar functionalities. The rest of the API still exposed by OMAP's iommu will be evaluated and eventually either added to the generic IOMMU API (if relevant), or completely removed. The intention is that OMAP's iommu driver will eventually not expose any public API.

Move OMAP's iommu drivers to the dedicated iommu drivers folder. While OMAP's iovmm (virtual memory manager) driver does not strictly belong to the iommu drivers folder, move it there as well, because it's by no means OMAP-specific (in concept. technically it is still coupled with OMAP's iommu). Eventually, iovmm will be completely replaced with the generic, iommu-based, dma-mapping API.

2011-08-26omap: iommu: migrate to the generic IOMMU APIOhad Ben-Cohen
Migrate OMAP's iommu driver to the generic IOMMU API, so users can stay generic, and any generic IOMMU functionality can be developed once in the generic framework. Migrate omap's iovmm (virtual memory manager) to the generic IOMMU API, and adapt omap3isp as needed, so the latter won't break. The plan is to eventually remove iovmm completely by replacing it with the (upcoming) IOMMU-based DMA-API. Tested on OMAP3 (with omap3isp) and OMAP4 (with rpmsg/remoteproc).

have irq. The previous rtc-s3c had two issues related with its IRQ. 1. Users cannot open rtc multiple times because an open operation calls request_irq on the same IRQ. (e.g., two user processes wants to open and read RTC time from rtc-s3c at the same time) 2. If alarm is set and no one has the rtc opened with filesystem (either the alarm is set by kernel/boot-loader or user set an alarm and closed rtc dev file), the pending bit is not cleared and no further interrupt is invoked. When the alarm is used by the system itself such as a resume from suspend-to-RAM or other Low-power modes/idle, this is a critical issue. This patch mitigates these issues by calling request_irq at probe and free_irq at remove.

2011-08-25memcg: fix hierarchical oom lockingJohannes Weiner
Commit 79dfdaccd1d5 ("memcg: make oom_lock 0 and 1 based rather than counter") tried to oom lock the hierarchy and roll back upon encountering an already locked memcg. The code is confused when it comes to detecting a locked memcg, though, so it would fail and rollback after locking one memcg and encountering an unlocked second one. The result is that oom-locking hierarchies fails unconditionally and that every oom killer invocation simply goes to sleep on the oom waitqueue forever. The tasks practically hang forever without anyone intervening, possibly holding locks that trip up unrelated tasks, too.
