* of: eliminate of_device->node and dev_archdata->{of,prom}_nodeGrant Likely2010-05-1817-77/+16
| | | | | | | | | | | | | This patch eliminates the node pointer from struct of_device and the of_node (or prom_node) pointer from struct dev_archdata since the node pointer is now part of struct device proper when CONFIG_OF is set, and all users of the old pointer locations have already been converted over to use device->of_node. Also remove dev_archdata_{get,set}_node() as it is no longer used by anything. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* of: Always use 'struct device.of_node' to get device node pointer.Grant Likely2010-05-1842-158/+157
| | | | | | | | | | | | The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead.

* driver-core: Add device node pointer to struct deviceGrant Likely2010-04-288-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, platforms using CONFIG_OF add a 'struct device_node *of_node' to dev->archdata. However, with CONFIG_OF becoming generic for all architectures, it makes sense for commonality to move it out of archdata and into struct device proper. This patch adds a struct device_node *of_node member to struct device and updates all locations which currently write the device_node pointer into archdata to also update dev->of_node. Subsequent patches will modify callers to use the archdata location and ultimately remove the archdata member entirely.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Imre Deak <imre.deak@nokia.com> Signal handlers can use floating point, so prevent them to corrupt the main thread's VFP context. So far there were two signal stack frame formats defined based on the VFP implementation, but the user struct used for ptrace covers all posibilities, so use it for the signal stack too. Introduce also a new user struct for VFP exception registers. In this too fields not relevant to the current VFP architecture are ignored. Support to save / restore the exception registers was added by Will Deacon.

| * ARM: 6007/1: fix highmem with VIPT cache and DMANicolas Pitre2010-04-146-20/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The VIVT cache of a highmem page is always flushed before the page is unmapped. This cache flush is explicit through flush_cache_kmaps() in flush_all_zero_pkmaps(), or through __cpuc_flush_dcache_area() in kunmap_atomic(). There is also an implicit flush of those highmem pages that were part of a process that just terminated making those pages free as the whole VIVT cache has to be flushed on every task switch. Hence unmapped highmem pages need no cache maintenance in that case. However unmapped pages may still be cached with a VIPT cache because the cache is tagged with physical addresses. There is no need for a whole cache flush during task switching for that reason, and despite the explicit cache flushes in flush_all_zero_pkmaps() and kunmap_atomic(), some highmem pages that were mapped in user space end up still cached even when they become unmapped. So, we do have to perform cache maintenance on those unmapped highmem pages in the context of DMA when using a VIPT cache. Unfortunately, it is not possible to perform that cache maintenance using physical addresses as all the L1 cache maintenance coprocessor functions accept virtual addresses only. Therefore we have no choice but to set up a temporary virtual mapping for that purpose. And of course the explicit cache flushing when unmapping a highmem page on a system with a VIPT cache now can go, which should increase performance. While at it, because the code in __flush_dcache_page() has to be modified anyway, let's also make sure the mapped highmem pages are pinned with kmap_high_get() for the duration of the cache maintenance operation. Because kunmap() does unmap highmem pages lazily, it was reported by Gary King <GKing@nvidia.com> that those pages ended up being unmapped during cache maintenance on SMP causing segmentation faults.

When initializaing the IOMMU, we attach devices to their domains before the IOMMU is fully (re)initialized. Attaching a device will issue some important invalidations. In the context of the newly kexec'd kdump kernel, the IOMMU may have stale cached data from the original kernel. Because we do the attach too early, the invalidation commands are placed in the new command buffer before the IOMMU is updated w/ that buffer. This leaves the stale entries in the kdump context and can renders device unusable. Simply enable the IOMMU before we do the attach.

This can leave the device using stale cached IOMMU data, and result in a non-functional device after it's re-bound to the host driver. For example, I see this upon rebinding: AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8000 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8040 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8080 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a80c0 flags=0x0050] 0000:02:00.0: eth2: Detected Hardware Unit Hang: ...

I didn't revert the register mapping, so we still use the same calling convention as kvm. KVM in more recent incarnations stopped injecting a fault when a guest tried to use the VMCALL instruction from ring 1, so lguest under kvm fails to make hypercalls. It was nice to share code with our KVM cousins, but this was overreach.

We run into this problem with the PLLB on the at91: ohci-at91 disables the PLLB when going to suspend. The slowclock code however tries to do the same: It saves the PLLB register value and when restoring the value during resume, it waits for the PLLB to lock again. However the PLL will never lock and the loop would run into its timeout because the slowclock code just stored and restored an empty register. This fixes the problem by only restoring PLLA/PLLB when they were enabled at suspend time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This area contains the Nand Flash controller registers. There is no need to map them statically as the Nand driver uses ioremap(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freescale redboot passes the silicon revision via ATAG_REVISION. Remove this bootloader dependency by doing the same as redboot does in the Kernel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This looks cleaner and allows us to call mx51_revision later when we can use ioremap to determine the silicon revision dynamically. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
