Andrew Turner 8daee410d2 vm: Use vmem_xalloc in kva_alloc
The kernel_arena used in kva_alloc has the qcache disabled. vmem_alloc
will first try to use the qcache before falling back to vmem_xalloc.

Rather than trying to use the qcache in vmem_alloc just call
vmem_xalloc directly.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
