ddb/amd64: Don't go out of the way to detect invalid addresses.

db_disasm had logic to detect invalid addresses before trying to
disassemble them.  But when disassembling a null instruction address,
the logic to detect invalid addresses itself tried to dereference an
invalid address.

db_get_value can already handle this situation gracefully, so there is
no need for this faulty fault-avoidance logic.

Fixes double-fault in ddb on calling null function pointers.  With
any luck, this should make diagnosing such bugs easier in the future!

ddb/i386: Don't go out of the way to detect invalid addresses.
db_read_bytes already does this better (but didn't at the time this
check was originally added back in 1998).  Not sure if this code had
the same mistake as the amd64 code causing it to trip over its own
shoelaces, but there should be no need for it here.

 s/TRUE/true/ and s/FALSE/false/ to make crash(8) compilable.

Catch up FreeBSD and OpenBSD's changes. Not completed but it's better than
before:
- Add support rdrand, rdseed, fxrstor, ldmxcsr, stmxcsr, xsare, xrstor,
  xsaveopt, cflush and some others.
- Check REX bit correctly.
- Print correct register.
- Fix a lot of bugs.
- KNF.

 Add missing check for db_Grp9. This change fixes a bug that cmpxchg8b can't
be disassembled.

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Make ddb compile and work in userspace. Mostly this is comprised of three
types of changes:

- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.

- Use db_read_bytes() instead of accessing kernel structures directly,
  and similar changes.

- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

merge yamt-x86pmap branch.

- reduce differences between amd64 and i386.  notably, share pmap.c
  between them.  it makes several i386 pmap improvements available to
  amd64, including tlb shootdown reduction and bug fixes from Stephan Uphoff.
- implement deferred pmap switching for amd64.
- remove LARGEPAGES option.  always use large pages if available.
  also, make it work on amd64.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Merge Bill Sommerfeld's i386 MP branch. This code has some known
caveats, but works quite well in a lot of MP cases, and all
UP cases that I have tested. Parts of this will hopefully be
reworked in the not-too-distant future.

file db_disasm.c was added on branch sommerfeld_i386mp_1 on 2001-09-03 19:48:09 +0000

go back to the first version of the pte/pde dance now that kvtopte()
has been changed to consisently return a pointer into the recursive
page table mapping.

constify

actually, pte is normally in user address space, but can also be in kernel
address space for LARGEPAGES kernel; to handle both, do the same dance
as for loc

db_disasm(): pte is in kernel address space, so use kvtopte() to get pde,
otherwise it would trip over KASSERT() in vtopte() and cycle

examine the PDE in addition to the PTE when checking for valid mappings.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Use kvtopte() for kernel addresses.

%r, %n -> db_format_radix()

printf format safety

Interface change: db_printsym() takes a third argument, pr, a function
pointer indicating how to print the symbol. This allows db_printsym()
to called in places where db_printf() is not an appropriate output
function.

While straightforward, apologies in advance if I've introduced any minor
syntax errors; I was unable to test compilation this on all the affected
platforms.

Add: cmpxchg8b, wrmsr, rdtsc, rdmsr, rdpmc, rsm.  From FreeBSD.

Pullup copyright text corrections.

Fix a pasto in copyright text which has been procreating like rabbits..

vm_offset_t -> {vaddr_t,paddr_t}, vm_size_t -> vsize_t

remove assumption about code aligment after "jmp"
(is not worth the possible confusion)

Fix PR # kern/68 by ensuring that a PC has a valid mapping before attempting
to disassemble it.

Prototype and gcc -Wall cleanups

Fix #includes.

Fix disassembly of `cmpxchg' instructions.

Sigh.  If you're going to pretend to be a function, you might as well act like
one...

Closer to KNF...

New i386 code.
