rename flash_cd to vrflash_cd, since device was renamed to vrflash.

Fixes hpcmips LCARD config linking issue that flash_cd is undefined.

hpcmips/vrflash(4): custom DPRINTF definition requires additional brackets
around the arguments.

Fixes FLUSH_DEBUG build.

However the driver fails to link due to missing reference to flash_cd,
my guess because of obsoleted flash device-major.

Sync w/ HEAD.

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

Resolve a couple of conflicts (result of the uimin/uimax changes)

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

Rebase to HEAD as of a few days ago.

Rebase.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

Support for Laser5's L-Card+ Embedded CPU Board
===============================================

This code enables NetBSD to support for NEC VR4181 CPU and some
devices on L-Card+ board.

NEC VR4181
----------

NEC VR4181 is a embedded CPU which has MIPS processor core and
integrated I/O devices within a package.  The basic architecture of
VR4181 is similar to other VR41xx family CPU.  Some integrated devices
are compatible to another VR41xx series CPU and some are not.

VR4181 has integrated devices listed bellow:

	- Two of 16550 compatible UART
	- Compact Flash controller
	- ISA bus controller
	- Audio CODEC
	- A/D converters
	- LCD driver
	- Touch panel controller
	- General purpose I/O


L-Card+ Embedded CPU Board
--------------------------

L-Card+ is name card sized CPU board for embedded system.  It is soled
by Laser5 (http://www.laser5.co.jp/) with Linux installed.

L-Card+ has following devices:

	- 16Mbyte flash memory (Intel 28F128)
	- 16Mbyte SDRAM
	- CS8900A Ethernet controller and RJ45 port
	- RS232C line driver and external connector
	- Compact Flash socket
	- A pair of Mezzanine connector for extension board
	- Some on-board LEDs
