linux-toradex.git/include/asm-arm, branch v2.6.20.21 Linux kernel for Apalis and Colibri modules [PATCH] iop13xx: fix i/o address translation 2007-06-11T18:37:08+00:00 Dan Williams dan.j.williams@intel.com 2007-05-02T18:43:19+00:00 90ac7887638743b9d204d22fcef8c7db5e2f55a0 PCI devices were being programmed with an incorrect base address value. This patch moves I/O space into a 16-bit addressable region and corrects the i/o offset. Much thanks to Martin Michlmayr for tracking this issue and testing debug patches.

[ARM] 4111/1: Allow VFP to work with thread migration on SMP 2007-01-25T16:35:29+00:00 Catalin Marinas catalin.marinas@arm.com 2007-01-24T17:47:08+00:00 c6428464894889e110418928e6b37dc2eb4cee56 The current lazy saving of the VFP registers is no longer possible with thread migration on SMP. This patch implements a per-CPU vfp-state pointer and the saving of the VFP registers at every context switch. The registers restoring is still performed in a lazy way.

[ARM] Resolve fuse and direct-IO failures due to missing cache flushes 2007-01-08T19:49:58+00:00 Russell King rmk@dyn-67.arm.linux.org.uk 2006-12-30T23:17:40+00:00 6020dff09252e3670a89edb36baaa4afb9b10d15 fuse does not work on ARM due to cache incoherency issues - fuse wants to use get_user_pages() to copy data from the current process into kernel space. However, since this accesses userspace via the kernel mapping, the kernel mapping can be out of date wrt data written to userspace. This can lead to unpredictable behaviour (in the case of fuse) or data corruption for direct-IO. This resolves debian bug #402876 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
