87ed2b7f5a A new implementation of the loader block cache
The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy.
Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks.
Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device.
The cache also implements limited read-ahead to increase performance.
To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache.

Booting from a virtual CD over IPMI:
0ms latency, before: 27 second, after: 7 seconds
60ms latency, before: over 12 minutes, after: under 5 minutes.

bbcfaa4eb8 Implement simple ops for umass_disk
The initial IOCTL implementation supports reading disk physical
geometry.
Two additional functions were added. They allow reading/writing raw
data to the disk (default partition).

09a37b41c5 Do not zero memory in umass_detach
The detach function is called very often, for example from
get_capacity function. We don't want to loose any pointers
here, so disable detaching for umass driver.

not the RAW pointer to the memory space.

92dbec66f2 Merge from CheriBSD:
Make the sysinit tool a build tool rather than building in with
/usr/bin/cc and running it from OBJDIR.  (It will be moved to usr.bin
once a manpage is written and a few style cleanups are done.)

Split the makefile bits for Hans' kernel shim layer into their own
includable kshim.mk.

Move USB support into a .mk file so loaders can include it.

6950c75f40 - Move scratch data from the USB bus structure to the USB device structure
so that simultaneous access cannot happen. Protect scratch area using
the enumeration lock. Also reduce stack usage in usbd_transfer_setup()
by moving some big stack members to the scratch area. This saves around
200 bytes of stack.
- Fix a whitespace.
