Also, the length field is mangled causing the hardware to think the registration is much larger than it really is. The fix is to remove the page alignment restriction as well the incorrect length adjustment. Also make sure that all buffers after the first start at a page boundary, and all buffers except the last end on a page boundary.

For INIT_HCA this causes problems when had more than 2^18 are QPs configured, since the command takes more than 1 second to complete. All other commands have 60-second timeouts. This patch makes the above commands consistent with the rest of the commands (and with the chip documentation).

The solution is to enable/disable NAPI in ipoib_ib_dev_{open/stop}() instead of in ipoib_{open/stop}(), and sync NAPI on the INITIALIZED flag instead on the ADMIN_UP flag. This way NAPI will be disabled when ipoib_drain_cq() is called. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1587>.

It ends up transferring data from irq handler with both local irq and HD_IRQ disabled. The only place it actually does something is while transferring the first block of a request which it does with HD_IRQ disabled but local irq enabled. Unfortunately, the dancing is horribly broken from locking POV. IRQ and timeout handlers access block queue without grabbing the queue lock and running the driver in SMP configuration crashes the whole machine pretty quickly. Remove meaningless irq enable/disable dancing and add proper locking in issue, irq and timeout paths. Signed-off-by: Tejun Heo <tj@kernel.org>

However, that would force PCI on for QPACE, which also selects PPC_CELL_NATIVE. So instead move the select of PPC_OF_PLATFORM_PCI and PCI under both IBM_CELL_BLADE and CELLEB.

For some reason we didn't do this on ppc32 builds. This hadn't been an issue until commit 8d30c14c ("powerpc/mm: Rework I$/D$ coherency (v3)"), which had as a side effect that we are now enforcing execute permissions to some extent on 32-bit 4xx and Book E processors. This fixes it by defining elf_read_implies_exec on 32-bit to turn on the read-implies-exec behaviour on programs that are sufficiently old that they don't have a PT_GNU_STACK program header.

This patch adds a workaround for this, hardcoding the number of chipselects to one for sequioa/rainer board models and reading the actual value from the memory controller register DDR0_10 otherwise. It also fixes another error in the way ibm4xx_denali_fixup_memsize calculates memory size. When testing the DDR_REDUC bit, the polarity is backwards. A "1" implies 32-bit wide memory while a "0" implies 64-bit wide memory.
