profile_pc() used thread_saved_fp() with the current task. However, thread_saved_fp() only returns sane values when called for threads which are presently sleeping, so this caused an oops. Instead, use regs->ARM_fp, which correspond with the frame pointer.

Make PA-RISC use the generic interrupt handling code. We need one tiny change to the generic code -- the addition of a data pointer to irq_desc. This shouldn't be a problem in terms of increasing size of irq_desc for other architectures as the struct is cacheline aligned. It's now 32 bytes on 32-bit platforms and 44/48 bytes on 64-bit platforms (assuming spinlock_t is 4 bytes on 32-bit and 4 or 8 bytes on 64-bit). Signed-off-by:

The input layer wants to send us an entropy event per input event and who are we to argue? Create add_input_randomness with an input-friendly interface and kill the remaining two keyboard and mouse sources. This eliminates lots of duplicate entropy events while covering all the input bases nicely. We now get two events per keystroke as we should, one down and one up. Signed-off-by:

The input layer is now sending us a bunch of events in a row for each actual event. This shows up weaknesses in the periodicity detector and using the high clock rate from get_clock: each keystroke is getting accounted as 10 different maximal-entropy events. A brief touch on a trackpad will generate as much as 2000 maximal entropy events which is more than 2k of /dev/random output. IOW, we're WAY overestimating input entropy. Here's one keystroke: random 0024 0000 0000: mouse event random 0035 0000 0000: added 11 entropy credits to input random 0035 0000 0000: mouse event random 0046 0000 0000: added 11 entropy credits to input random 0046 0000 0000: mouse event random 0056 0000 0000: added 10 entropy credits to input random 0056 0000 0000: keyboard event random 0067 0000 0000: added 11 entropy credits to input random 0067 0000 0000: mouse event random 0078 0000 0000: added 11 entropy credits to input random 0078 0000 0000: awake random 0078 0000 0000: reading 128 bits random 0078 0000 0000: going to reseed blocking with 128 bits (128 of 0 requested) random 0078 0000 0000: trying to extract 128 bits from input random 0006 0000 0000: debiting 72 entropy credits from input random 0006 0072 0000: added 72 entropy credits to blocking random 0006 0072 0000: trying to extract 128 bits from blocking random 0006 0000 0000: debiting 72 entropy credits from blocking random 0006 0000 0000: read got 72 bits (56 still needed) random 0006 0000 0000: reading 56 bits random 0006 0000 0000: going to reseed blocking with 64 bits (56 of 0 requested random 0006 0000 0000: trying to extract 64 bits from input random 0006 0000 0000: debiting 0 entropy credits from input random 0006 0000 0000: trying to extract 56 bits from blocking random 0006 0000 0000: debiting 0 entropy credits from blocking random 0006 0000 0000: read got 0 bits (56 still needed) random 0006 0000 0000: sleeping random 0006 0000 0000: mouse event random 0017 0000 0000: added 11 entropy credits to input random 0017 0000 0000: mouse event random 0028 0000 0000: added 11 entropy credits to input random 0028 0000 0000: mouse event random 0038 0000 0000: added 10 entropy credits to input random 0038 0000 0000: keyboard event random 0049 0000 0000: added 11 entropy credits to input random 0049 0000 0000: mouse event random 0060 0000 0000: added 11 entropy credits to input The first step to fixing this is to check periodicity and estimate entropy against a slow clock like jiffies. We continue to mix in get_clock() rather than jiffies where available. This throws away most of the duplicate events and gives us more sensible entropy estimates, but we still duplicates from input.c and keyboard.c. Signed-off-by:

Patch for the Marvell MultiProtocol Serial Controller (MPSC). This ctlr is on a series of host bridges (and other things) for PPC and MIPS processors. The ctlr operates similar to a typical network controller with send and receive rings. Unfortunately there are many errata so you will see some "unusual" things in the code. For example: a) An erratum prevents the reading of several registers on the ctlr (writing is okay). To work around that, a local copy of what the registers are is kept and special macros are used to access those mirrored values. b) Another erratum says that the MPSC cannot be used to access cache coherent memory (and many of the systems I use are cache coherent). However, it seems to work okay as long as there are no snoop hits so there are macros in the code to manually manage the caches to prevent snoop hits. Each macro checks a flag to see if the manual cache mgmt is necessary as not all versions have the erratum. The driver seems to work well but more testing is needed and it is lacking KGDB support. I will get to both of those in time. Signed-off-by:
