Adding a pool of MSI-X vectors and EQs that can be used explicitly by mlx4_core customers (mlx4_ib, mlx4_en). The consumers will assign their own names to the interrupt vectors. Those vectors are not opened at mlx4 device initialization, opened by demand. Changed the max number of possible EQs according to the new scheme, no longer relies on on number of cores. The new functionality is exposed through mlx4_assign_eq() and mlx4_release_eq(). Customers that do not use the new API will get completion vectors as before.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

The current implementation allocates a single host page for EQ context memory, which was OK when we only allocated a few EQs. However, since we now allocate an EQ for each CPU core, this patch removes the hard-coded limit (which we exceed with 4 KB pages and 128 byte EQ context entries with 32 CPUs) and uses the same ICM table code as all other context tables, which ends up simplifying the code quite a bit while fixing the problem. This problem was actually hit in practice on a dual-socket Nehalem box with 16 real hardware threads and sufficiently odd ACPI tables that it shows on boot SMP: Allowing 32 CPUs, 16 hotplug CPUs so num_possible_cpus() ends up 32, and mlx4 ends up creating 33 MSI-X interrupts and 33 EQs. This mlx4 bug means that mlx4 can't even initialize at all on this quite mainstream system.

The current MTT allocator uses kmalloc() to allocate a buffer for its buddy allocator, and thus is limited in the amount of MTT segments that it can control.

Commit 7ff93f8b ("mlx4_core: Multiple port type support") introduced support for different port types. As part of that support, SET_PORT is invoked to set the port type during driver startup. However, as a side-effect, for IB ports the invocation of this command also sets the port's capability mask to zero (losing the default value set by FW). To fix this, get the default ib port capabilities (via a MAD_IFC Port Info query) during driver startup, and save them for use in the mlx4_SET_PORT command when setting the port-type to Infiniband. This patch fixes problems with subnet manager (SM) failover such as <https://bugs.openfabrics.org/show_bug.cgi?id=1183>, which occurred because the IsTrapSupported bit in the capability mask was zeroed.

There was a bug in some versions of the mlx4 driver in mlx4_alloc_fmr(), which hardcoded the minimum acceptable page_shift to be 12. However, new ConnectX firmware can support a minimum page_shift of 9 (log_pg_sz of 9 returned by QUERY_DEV_LIM) -- so with old drivers, ib_fmr_alloc() would fail for ULPs using the device minimum when creating FMRs. To preserve firmware compatibility with released mlx4 drivers, the firmware will continue to return 12 as before for log_page_sz in QUERY_DEV_CAP for these drivers. However, to enable new drivers to take advantage of the available smaller page size, the mlx4 driver now first sets the log_pg_sz to the device minimum by setting a log_page_sz value to 0 via the MOD_STAT_CFG command and then reading the real minimum via QUERY_DEV_CAP.
