o Replace __riscv64 with (__riscv && __riscv_xlen == 64)
This is required to support new GCC 7.1 compiler.
This is compatible with current GCC 6.1 compiler.
RISC-V is extensible ISA and the idea here is to have built-in define
per each extension, so together with __riscv we will have some subset
of these as well (depending on -march string passed to compiler):
__riscv_compressed
__riscv_atomic
__riscv_mul
__riscv_div
__riscv_muldiv
__riscv_fdiv
__riscv_fsqrt

ceil(log2(sizeof(struct pfs_node))) is the same as before in both the ILP32

My change had good intentions, but the implementation was incorrect:
- printf was returning the number of characters in the format string
plus the NUL, but failed in two regards implementation wise:
-- the pathological case, printf(""), wasn't being handled properly since
the pointer is always incremented, so the value returned would be
off-by-one.
-- printf(3) reports the number of characters printed post-conversion via
vfprintf, etc.
- putchar(3) should return the character printed or EOF, not the number
of characters output to the screen.
My goal in making the change (again) was to increase parity, but as bde
pointed out these are freestanding functions, so they don't have to
conform to libc/POSIX. I argued that the functions should be named
differently since the implementation is different enough to warrant it
and to allow boot2 code to be usable when linked against sys/boot and
libstand and other libraries in base. I have no interest in pushing
this change forward more though, as the original concern I had behind
the change with zfsboottest was resolved in r321849 and r321852. The
next person that updates the toolchain gets to deal with the
inconsistency if it's flagged by a newer compiler.

- Store the symbol table contents in an anonymous swap-backed object. Have
mmap(/dev/ksyms) map that object, and stop mapping the symbol table into
the calling process in ksyms_open(). Previously we would cache a pointer
to the pmap of the opening process, and mmap(/dev/ksyms) would create a
mapping using the physical address found by a pmap lookup at the initial
mapping address. However, this assumes that the cached pmap is valid,
which may not be the case. [1]
- Remove the ksyms ioctl interface. It appears to have been added to work
around a limitation in libelf that no longer exists; see r321842.
Moreover, the interface is difficult to support and isn't present in
illumos. Since ksyms was added specifically to support lockstat(1), it
is expected that this removal won't have any real impact.
- Simplify ksyms_read() to avoid unnecessary copying.
- Don't call the device handle destructor if we fail to capture a snapshot
of the kernel's symbol table. devfs will do that for us.

"br" or "bridge" where - according to the terminology outlined in

r163516 - the bus is meant and used instead. Some of these instances
are also rather old, while those in e. g. mmc_subr.c are as new as
r315430 and were caused by choosing mmc_wait_for_request(), i. e. the
one pre-r315430 outliner existing in mmc.c, as template for function
parameters in mmc_subr.c inadvertently. This correction translates to
renaming "brdev" to "busdev" and "mmcbr" to "mmcbus" respectively as
appropriate.
While at it, also rename "reqdev" to just "dev" in mmc_subr.[c,h]

topologies are actually possible in form of so called "shared buses"

Note that the HDMI init code was writing into the wrong register before
this change. Apparently whatever it wrote to was harmless, and apparently
HDMI was working because uboot had set up the right bits.
