To support MPC5125 PSC in this driver we have to provide further psc_ops functions for SoC specific register accesses. Add new register access functions to the psc_ops structure and provide MPC52xx and MPC512x specific implementation for them. Then replace remaining direct register accesses in the driver by appropriate psc_ops function calls. The subsequent patch can now add MPC5125 specific set of psc_ops functions.

The only reason uaccess routines might sleep is if they fault. Make this explicit for all architectures. 2. a voluntary preempt point in uaccess functions means compiler can't inline them efficiently, this breaks assumptions that they are very fast and small that e.g. net code seems to make. remove this preempt point so behaviour matches what callers assume. 3. Accesses (e.g through socket ops) to kernel memory with KERNEL_DS like net/sunrpc does will never sleep. Remove an unconditinal might_sleep in the inline might_fault in kernel.h (used when PROVE_LOCKING is not set). 4. Accesses with pagefault_disable return EFAULT but won't cause caller to sleep. Check for that and avoid might_sleep when PROVE_LOCKING is set. I'd like these changes to go in for 3.11: besides a general benefit of improved consistency and performance, I would also like them for the vhost driver where we want to call socket </pre> Michael S. Tsirkin 2013-05-24T14:17:32 http://comments.gmane.org/gmane.linux.ports.ppc.embedded/59528 <pre>Hi Linus ! Here are a few more powerpc fixes for 3.10. Some more P8 related bits, a bunch of fixes for our P7+/P8 HW crypto drivers, some added workarounds for those radeons that don't do proper 64-bit MSIs and a couple of other trivialities by myself. Cheers, Ben. The following changes since commit 519fe2ecb755b875d9814cdda19778c2e88c6901: Merge branch 'leds-fixes-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds (2013-05-21 11:41:07 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc.git merge for you to fetch changes up to f1dd153121dcb872ae6cba8d52bec97519eb7d97: powerpc/pseries: Make 32-bit MSI quirk work on systems lacking firmware support (2013-05-24 18:16:54 +1000) ---------------------------------------------------------------- Benjamin Herrenschmidt (5): powerpc: Fix TLB cleanup at boot on POWER8 powerpc/pci: Fix bogus message at boot about empty memory resources powerpc/powernv: Fix con</pre> Benjamin Herrenschmidt 2013-05-24T09:41:30 http://comments.gmane.org/gmane.linux.ports.ppc.embedded/59522 <pre>This adds the remaining two hypercalls defined by PAPR for manipulating the XICS interrupt controller, H_IPOLL and H_XIRR_X. H_IPOLL returns information about the priority and pending interrupts for a virtual cpu, without changing any state. H_XIRR_X is like H_XIRR in that it reads and acknowledges the highest-priority pending interrupt, but it also returns the timestamp (timebase register value) from when the interrupt was first received by the hypervisor. Currently we just return the current time, since we don't do any software queueing of virtual interrupts inside the XICS emulation code. These hcalls are not currently used by Linux guests, but may be in future. Signed-off-by: Paul Mackerras &lt;paulus&lt; at &gt;samba.org&gt; --- Unfortunately I missed these two hcalls in the previous submissions. It would be good to get this patch into 3.10 so we don't have a kernel version with these calls missing from the API, in case future guest kernels want to use them.

And kernel also already has prepared a default effective implementation for the architectures which is unwilling to implement it by themselves (e.g. arm64, c6x, h8300, hexagon, m32r, metag, microblaze, openrisc, score, tile, um, unicore32, xtensa).
