Current sched_clock() implementations on ARM cause unbootable kernels with PRINTK_TIME support enabled. To avoid this, provide a basic printk_clock() implementation which avoids sched_clock() being called before the page tables have been set up.

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 However, since this accesses userspace via the kernel mapping, the kernel mapping can be out of date wrt data written to userspace.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: NRussell King <rmk+kernel@arm.linux.org.uk>

If the kernel attempts to execute a CP1 or CP2 instruction and it aborts, and a FP emulator is not loaded, we try to return as if to a user context, instead of the proper kernel context. Since the fault came from kernel mode, we must use the kernel return paths. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

If PG_dcache_dirty is set for a page, we need to flush the source page before performing any copypage operation using a different virtual address.

Since iop13xx defines the PCI I/O spaces with physical resource addresses the __io macro needs to perform the physical to virtual conversion. I incorrectly assumed that this would be handled by ioremap, but drivers (like e1000) directly dereference the address returned from __io.

More fixes to build breakage from the work_struct changes ... this updates the tps65010 driver. Plus, fix some dependencies related to the way it's used on the OMAP OSK: force static linking there, since the resulting kernel can't link. NOTE that until the i2c core gets fixed to work without SMBUS_QUICK, kernels needing this driver must still use "tps65010.force=0,0x48" on the command line.
