Fix libspl/asm-generic/atomic for VPATH build Currently, asm-generic/atomic.c is compiled into a .S file, with a comment saying this is to simplify the upper-level Makefile. However, this doesn't work properly with a VPATH build, which would require better logic to deal with generated sources correctly. It also doesn't seem more complex to just specify the .c/.S source file, depending on the cpu, instead of only the source directory in lib/libspl/Makefile.am, which eliminates the need to do the intermediate compilation.

Ask libtool to stop hiding some errors For #13083, curiously, it did not print the actual error, just that the compile failed with "Error 1". In theory, this flag should cause it to report errors twice sometimes. In practice, I'm pretty okay with reporting some twice if it avoids reporting some never.

Move libspl_assertf into .c file Variadic functions cannot be inlined. libspl_assertf ends up being duplicated in every file that uses it. Fix this by moving the function into a new assert.c.

Support parallel build trees (VPATH builds) Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake.

libspl: implement atomics in terms of atomics This replaces the generic libspl atomic.c atomics implementation with one based on builtin gcc atomics. This functionality was added as an experimental feature in gcc 4.4. Today even CentOS 7 ships with gcc 4.8 as the default compiler we can make this the default. Furthermore, the builtin atomics are as good or better than our hand-rolled implementation so it's reasonable to drop that custom code.

ABD optimized page allocation code * Convert ABD to use the Linux Kernel scatterlist implementation instead of the hand rolled one from illumos. * Scatter ABDs are preferentially populated with higher order compound pages from a single zone. Allocation size is progressively decreased until it can be satisfied without performing reclaim or compaction. * An alternate page allocator is provided for kernels older than 3.6 and for CONFIG_HIGHMEM systems. This allocator is designed as a fallback for maximum compatibility. * Extended abdstats to provide visibility in the the allocator. * Add cached value for PAGESIZE in userspace.

Check for strlcat and strlcpy This partially reverts commit 8005ca4 by moving the strlcat() and strlcpy() compatibility implementations back to their original location. In addition, these two functions were added to the AC_CHECK_FUNCS macro. When these functions are available from the C library, HAVE_STRLCAT and HAVE_STRLCPY will be defined and library version used. Otherwise the compatibility version is built.

However, going forward they should be versioned. This commit versions all of the libraries to 1.0.0. From here on out this version must be updated to reflect changes to the library.

cppcheck: integrete cppcheck In order for cppcheck to perform a proper analysis it needs to be aware of how the sources are compiled (source files, include paths/files, extra defines, etc). All the needed information is available from the Makefiles and can be leveraged with a generic cppcheck Makefile target. So let's add one. Additional minor changes: * Removing the cppcheck-suppressions.txt file. With cppcheck 2.3 and these changes it appears to no longer be needed. Some inline suppressions were also removed since they appear not to be needed. We can add them back if it turns out they're needed for older versions of cppcheck. * Added the ax_count_cpus m4 macro to detect at configure time how many processors are available in order to run multiple cppcheck jobs. This value is also now used as a replacement for nproc when executing the kernel interface checks. * "PHONY =" line moved in to the Rules.am file which is included at the top of all Makefile.am's. This is just convenient becase it allows us to use the += syntax to add phony targets. * One upside of this integration worth mentioning is it now allows `make cppcheck` to be run in any directory to check that subtree. * For the moment, cppcheck is not run against the FreeBSD specific kernel sources. The cppcheck-FreeBSD target will need to be implemented and testing on FreeBSD to support this.
