LIB= kvm
Re-apply the part of r260022 that was reverted by r260030 with one significant difference: for LIB32 builds both TARGET_ARCH and MACHINE_ARCH are defined. TARGET_ARCH confusingly holds the architecture of the host (e.g. amd64), while MACHINE_ARCH holds the architecture were trying to build (e.g. i386). With both set and different, r260022 changed the behaviour to interpret the condition as building a cross-amd64 libkvm on i386, when obviously we're trying to build an i386 version on amd64. When COMPAT_32BIT is defined, we're building LIB32 and ignore the value of TARGET_ARCH as we did before.

SHLIB_MAJOR= 7
Use __SCCSID for SCCS IDs in libkvm sources. Rather than using #ifdef's around a static char array, use the existing helper macro from <sys/cdefs.h> for SCCS IDs. To preserve existing behavior, add -DNO__SCCSID to CFLAGS to not include SCCS IDs in the built library by default.

libkvm: bump WARNS to 6 after recent commits done to resolve warnings issues MFC after: 1 month Tested with: make tinderbox; clang 4.0.0 (amd64), gcc 4.2.1/6.3.0 (amd64) Sponsored by: Dell EMC Isilon

WARNS?= 6
Build lib/ with WARNS=6 by default. Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and lower it when needed. I'm setting WARNS?=0 for secure/. It seems secure/ includes the Makefile.inc provided by lib/. I'm not going to touch that directory. Most of the code there is contributed anyway.

Add support to libkvm for reading vmcores from other architectures. - Add a kvaddr_type to represent kernel virtual addresses instead of unsigned long. - Add a struct kvm_nlist which is a stripped down version of struct nlist that uses kvaddr_t for n_value. - Add a kvm_native() routine that returns true if an open kvm descriptor is for a native kernel and memory image. - Add a kvm_open2() function similar to kvm_openfiles(). It drops the unused 'swapfile' argument and adds a new function pointer argument for a symbol resolving function. Native kernels still use _fdnlist() from libc to resolve symbols if a resolver function is not supplied, but cross kernels require a resolver. - Add a kvm_nlist2() function similar to kvm_nlist() except that it uses struct kvm_nlist instead of struct nlist. - Add a kvm_read2() function similar to kvm_read() except that it uses kvaddr_t instead of unsigned long for the kernel virtual address. - Add a new kvm_arch switch of routines needed by a vmcore backend. Each backend is responsible for implementing kvm_read2() for a given vmcore format. - Use libelf to read headers from ELF kernels and cores (except for powerpc cores). - Add internal helper routines for the common page offset hash table used by the minidump backends. - Port all of the existing kvm backends to implement a kvm_arch switch and to be cross-friendly by using private constants instead of ones that vary by platform (e.g. PAGE_SIZE). Static assertions are present when a given backend is compiled natively to ensure the private constants match the real ones. - Enable all of the existing vmcore backends on all platforms. This means that libkvm on any platform should be able to perform KVA translation and read data from a vmcore of any platform.
