eliminating duplicated code in the various pmap implementations.
Micro-optimize vm_phys_free_pages().
Introduce vm_phys_free_contig(). It is fast routine for freeing an
arbitrary number of physically contiguous pages. In particular, it
doesn't require the number of pages to be a power of two.
Use "u_long" instead of "unsigned long".
Bruce Evans (bde@) has convinced me that the "boundary" parameters
to kmem_alloc_contig(), vm_phys_alloc_contig(), and
vm_reserv_reclaim_contig() should be of type "vm_paddr_t" and not
"u_long". Make this change.

Our copy was a bastardization of the "older" (probably original?) and
shorter version of the poem; and the "newer" version that is better
known, and arguably more popular. Standardize on the latter.

POSIX says the exit status of a for loop without any items shall be 0. There
are no exceptions if the exit status of the previous command was not 0 or if
the item list contains a command substitution with non-zero exit status.

benefits other languages).

their length.
Without this, an error frame mbuf would:
* have its size adjusted;
* thrown at the radiotap code;
* then since it's never consumed, the rxbuf/mbuf is then re-added to the
RX descriptor list with the small size;
* .. and the hardware ends up (sometimes) only DMA'ing part of a frame into
the small buffer, chaining RX frames together (setting the more flag).
I discovered this particular issue when doing some promiscuous radiotap
testing; I found that I'd occasionally get rs_more set in RX descriptors
w/ the first frame length being very small (sub-100 bytes.) The driver
handles 2-descriptor RX frames (but not more), so this still worked; it
was just odd.
This is suboptimal and may benefit from being replaced with caching
the m_pkthdr_len and m_len fields, then restoring them after completion.
That required to increase the LINE field to fit the output of -b.
While here, change the row() function to take a const argument.

bge(4) sends BGE_FW_CMD_DRV_ALIVE command to firmware every 2
seconds. BGE_FW_CMD_DRV_ALIVE command requires 4 bytes data. This
data contains timeout value in seconds until the next
BGE_FW_CMD_DRV_ALIVE command.
Broadcom recommends driver set the value 3 times longer than the
interval that it sends BGE_FW_CMD_DRV_ALIVE. Currently bge(4) uses
3 seconds so probably we have to increase it in future and use
different ALIVE command(e.g. BGE_FW_CMD_DRV_ALIVE3).
No functional changes.
This bit(SW event 7 in publicly available data sheet) is used to
make RX CPU handle a firmware command and the bit is automatically
cleared after RX CPU completed the command.
Generally firmware command takes the following steps.
1. Write BGE_SRAM_FW_CMD_MB with a command.
2. Write BGE_SRAM_FW_CMD_LEN_MB with the length of the command in bytes.
3. Write BGE_SRAM_FW_CMD_DATA_MB with actual command data.
4. Generate BGE_RX_CPU_EVENT and let firmware handle the command.
5. Wait for the ACK of the firmware command.
