Elliott Mitchell 037946dc9b kern/rman: remove rman_reserve_resource_bound(), partially revert 13fb665772
Not once has rman_reserve_resource_bound() ever been used.  There are
though several uses of RF_ALIGNMENT.  In light of this remove this
extra and leave the actually used portion in place.

This partially reverts commit 13fb665772.

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.
