Note rmind-uvmplock branch merge.

(rmind)

for booke and ibm4xx evbppc systems, set module_machine to to either
"powerpc-ibm4xx" or "powerpc-booke".

(mrg)

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

(rmind)

Fix printf formats in DEBUG case.

(tsutsui)

Fix the build of ALL kernel (hi matt@).

(rmind)

No need to initialize interrupt evcnt(9) so earlier, so remove phase arg
from intr_init() and initialize all stuff in cpu_configure(9) as other ports
rather than in mach_init() and mbattach().

(tsutsui)

- misc KNF
- use device_xname(), device_unit(), and device_class()

(tsutsui)

Sync RUMP's rump_etfs_remove() and uvm_aio_aiodone() with branch changes.

(rmind)

Sync RUMP's uvm_pagealloc_strat() and processpage() with branch changes.

(rmind)

Do not call uvm_loan_init() twice.

(rmind)

note that sparc MODULAR works and is enabled now.

(mrg)

enable options MODULAR, now that it is tested to work.

(mrg)

sparc relative reloctions are busted here; copy the sparc64 style
which seems to make things work fine, and also seems to follow what
ld.elf_so does.

this makes modules work in my limited testing.

(mrg)

Set iospace and virtual_end address properly.
Fixes TLB miss panic during device attach on emips.

(tsutsui)

sync with head

(rmind)

Change i_len in ieee80211req to be unsigned and fix other signed/unsigned
issues. From Dan Rosenberg (drosenberg at vsecurity dot com).

(christos)

turn on printf warnings for all the printf-like atf functions.

(christos)

Turn warns on for all tests and fix all the bugs.

(christos)

format fixes, prototype fixes, const fixes

(christos)

split device_t/softc.

(nonaka)

document OLDPWD and cd -

(christos)

Added LCD-8000UD-DVI entry.

(nonaka)

regen.

(nonaka)

Added LCD-8000UD-DVI entry.

(nonaka)

MBR magic exists at the beginning of 'a' partition, BPB is cleared.
Avoid to detect msdosfs incorrectly at boot time.

(nonaka)

Add iscsiattach(int), to be called when configured statically into a kernel.
Rename old iscsiattach->iscsi_attach, also iscsi_match and iscsi_detach,
and adjust their invocation.

iscsi now works when configured statically into a kernel.

(riz)

In debugging code: Use %p for pointers, %zu for size_t.  Don't cast
pointers to int.  Makes debug code compile on amd64.

(riz)

Fix build; p was not used, but l was passed to kauth.  Use curlwp directly.

(uebayasi)

Use %zu rather than cast

(sjg)

Use KASSERTMSG so if these trigger, we can see what exactly caused them to fire.

(matt)

If compiled with -msoft-float, make the compiler emit soft float code
by default.

(matt)

If we are compiling -msoft-float, define _SOFT_FLOAT

(matt)

Add missing no options GUR_BASE

(matt)

size_t on amd64 doesn't like %u, use a cast.

(sjg)

l isn't used.  nuke it.

(matt)

Use size_t for sizes, not int, so this can build on 64-bit platforms.

(riz)

Don't try to dereference a void pointer without proper cast.

(riz)

Do not print sizeof values in skip message.

(njoly)

Change default of GUR_BASE to 0xffe00000 which is used on more recent machines.
Add options GUR_BASE=0xe0000000 to MPC8548CDS and RB800

(matt)

If building the cross gcc for softfloat, add --with-float=soft so it will
default to it.

(matt)

Remove unneeded prototypes.

(njoly)

Remove newlines from various messages.

(njoly)

Do not call exit() after atf_tc_fail().

(njoly)

Protoize the inline to C89 and use const.
Optimizie KERNHIST_LOG slightly (saves 40KB over previous version).

(matt)

ehci_set_qh_qtd: terminate alternate next qTD pointer with EHCI_NULL, not 0

(jmcneill)

nanl() do use strtold(), not strtod().

(njoly)

do_sys_rename: Kill an unused variable.

(uebayasi)

- split device_t/softc
- struct proc -> struct lwp

XXX: this driver is not in the default kernels.

(tsutsui)

Split device_t/softc. Compile test only.

(tsutsui)

Disable integrated assembler for clang until the RNG instructions are
supported

(joerg)

Add a few more cases that need GNU as. One of the padlock instructions
is missing in LLVM. spl.S and lock_stubs.S break with patchfunc
otherwise.

(joerg)

Disable LLVM MC for spl.S for now. The different spllower sizes break
patchfunc.

(joerg)

Explicitly disable use of SSE. LLVM generates SSE by default on AMD64
and we certainly don't want that in the kernel.

(joerg)

Support $OLDPWD.  (christos@ will update the manual.)

Reviewd By: christos

(uebayasi)

add a driverFunc to tell the Xserver that this driver doesn't need PIO access
Now this works again on sparc64.

(macallan)

Appease rump.

(matt)

setting things once is enough.

(christos)

CADDR_T -> void *
boolean_t -> bool
struct device * -> device_t
struct cfdata * -> caddr_t
CFATTACH_DECL -> CFATTACH_DECL_NEW

(riz)

fix compilation.

(christos)

catch a case where an ip6 address with scope embedded was compared with
one without -- interestingly this didn't break the connection but just
caused a useless encapsulation
(this code needs to be rearranged to get it clean)

(drochner)

share more code.

(christos)

more "const"

(drochner)

Fix ATTR register definitions

(matt)

Correct definitions of USB_SNOOP registers.  Add USB_CONTROL register.

(matt)

For PPC_BOOKE, make BUS_DMA_COHERENT equal to BUS_DMA_NOCACHE.  Now USB
works again.  (which means USB uses of bus_dmamap_sync is broken).

(matt)

Move EHCI_DEBUG, OHCI_DEBUG, UHCI_DEBUG, USB_DEBUG, UHUB_DEBUG to opt_usb.h
(ya dependencies).
Cleanup usb_mem.c a little more and add block tracking code.  Help find
corruption problems.
Comment out the SPEED check for ETTF.  XXX why doesn't that work right?

(matt)

- device_t/softc split.
- use aprint_* function.

(nonaka)

PR/42642: Ed Ravin: Handle daemons that start with #!/usr/bin/env interp

(christos)

use 64-bit integers for GF128 multiplication on LP64 CPUs

(drochner)

dma_addr_t may not be a 64bit type, so add an explicit cast here instead
of silent truncation

(joerg)

Use a format string when printing strings

(joerg)

Annotate that gpiobus_close's return value is undesired here

(joerg)

-if an opencrypto(9) session is allocated, the driver is refcounted
and can not disappear -- no need to hold crypto_mtx to check the
driver list
(the whole check is questionable)
-crp->crp_cv (the condition variable) is used by userland cryptodev
exclusively -- move its initialization there, no need to waste
cycles of in-kernel callers
-add a comment which members of "struct cryptop" are used
by opencrypto(9) and which by crypto(4)
(this should be split, no need to waste memory for in-kernel callers)

(drochner)

Rework mvsoctmr(4), improving timekeeping accuracy

Inconveniently the Marvell hardware only counts down.
We need to reverse this for timecounter(9), and we need
to do it in a very lightweight way.

- use Timer0 for the clock interrupt
- use Timer1 for timecounter(9) and delay(9)
- drop statclock due to lack of timers (does anyone actually use this?)

(jakllsch)

Adapt to change to PCU.

(matt)

Input function is not used

(joerg)

Do not indent RETURN VALUES section (which was ignored because of
missing dash).

(njoly)

the BCM5785 is a PCIe chip but does not report PCIe capabilities.
Check for this chip explicitely and enable PCIe.
Fixes 'firmware handshake timeout'. Tested with root on nfs.

patch from msaitoh@

(cegger)

Use __arraycount

(matt)

and fix the sets for the addition of srp and evp tests in libcrypto

(spz)

add tests for evb and srp

(spz)

_gr_copy() can get called with fromgrp->gr_mem == NULL.

(sjg)

Remove few references to simple_lock.

(rmind)

Convert simple_lock/ltsleep to mutex/condvar and malloc to kmem.

(rmind)

Rework the cfdata similar to the way pad(4) does it, and explicitly
call config_cfdata_attach().  Now 'modunload iscsi' works as expected.

(riz)

- Use IPL_BIO (instead of IPL_SERIAL) for SPI.
- Convert simple_lock/ltsleep to mutex/condvar.

(rmind)

Convert simple_lock to mutex.

(rmind)

Mention a new ktrace(1) trace point.

(alnsn)

Also create device nodes for wd2 and wd3. Up to 4 disks in a NAS system are
not unusual.

(phx)

Factor out some duplicated code to simplify maintenance.  Reduces
the source file by ~100 lines, and amd64 object file shrinks by
~650 bytes.

No functional change intended.

(pgoyette)

Fix prologue macros order.

(njoly)

Support disk units from multiple IDE/SATA PCI controllers.

(phx)

Make GDIUM build again after matt-nb5-mips64 merge. untested as I don't have
this hardware, but I'll use this as a base for Lemote Fulong support.

(bouyer)

Rework to support more relocations.  Reorganize so code doesn't need to be
replicated over and over.

(matt)

Fiddle a bit with const's to make FAST_IPSEC compile.

(dyoung)

Restrict limit monitoring for Indicator sensors as well as for
Battery-charge sensors.

(pgoyette)

Instead of relying on the want-percent attribute, use the sensor
type to restrict value-based limits from Battery-capacity sensors.

(pgoyette)

Use prototypes from libi386.h.

(joerg)

G/C wbinvd

(joerg)

A small speedup, when mapping memory in bus_dmamem_map, if the memory is
cacheable and is in a single segment (physically contiguous) don't bother
allocating KVA for it, just use the physical address as the VA.

(matt)

mention combinations of flags

(yamt)

err -> errx where appropriate

(yamt)

Sync usage with man page.

(wiz)

Sort options. New sentence, new line.

(wiz)

Correct description for hw.swwdog.reboot behaviour.

(pgoyette)

add support for the interesting parts of ISO-2 and KOI8-R fonts
to the vga(4) driver

(drochner)

reduce typecasts and byte swapping

(drochner)

Update LLVM/Clang snapshot to 132736. This fixes two situations where
libraries could end up with text relocations.

(joerg)

When printing the header, convert values to names:
Use strlcpy to copy the name, not strncpy.

(matt)

Adjust types.

(jruoho)

Use atf_tc_skip() instead of #if 0.

(jruoho)

When delivering MSIs, sometimes after clearing the MSI but before the interrupt
routine get called the MSI reasserts and we loop around and would detect a
spurious interrupt.

So now we keep track of the interrupts we have serviced successfully for this
dispatch loop.  If we have to invoke an interrupt handler and that handler
indicates nothing was serviced, if we previously serviced it it isn't counter
as a spurious interrupt.

(matt)

Add an e500_idlespin to detect calls to idlespin when interrupts are blocked
or disabled.

(matt)

In INIT_CPUINFO, make L_CPU to set the cpu_info (just to be safe).

(matt)

Cleanup register use so that r5-r8 are preserved.  Take advantage of
changes to INIT_CPUINFO (it now saves curcpu to L_CPU(%r13)).

(matt)

Use a standard INSTALL.inc instead of duplicating it.  Make INSTALL
variants of mpc85xx kernels.

(matt)

Add a couple calls to splx(), from dyoung@.  The code now works under
DIAGNOSTIC without panic.

(riz)

Update in-kernel initiator so it builds on -current as a module.

XXX there is an spl bug which causes it to crash when DIAGNOSTIC which
needs to be fixed, though on a non-DIAGNOSTIC kernel I can mount a
volume from a local target and read files successfully under -current.

Lots of code cleanup is needed before moving into src, but this is a step.

(riz)

Be a bit cleaner and reduce the amount of namespace pollution

(joerg)

Fix typo.

(wiz)

Whitespace fix and sort SEE ALSO.

(wiz)

Catch up with addition of putstr32.S.

(joerg)

Add () that match operator order.

(joerg)

Temporarily comment out the 'stat_dir' test. It panics QEMU/i386 guests.

(jruoho)

Document PPS_SYNC for com(4) and zstty(4) (the only serial drivers
in which NetBSD currently supports the option), with cross reference
to ntpd(8) and options(4).

(fair)

Make pcu_save_all and pcu_discard_all KASSERTs accept LW_SYSTEM threads
since kthread_create will call lwp_create with lwp0 which may not be curlwp.

(matt)

Sort sections.

(wiz)

Add mpc85xx kernels.  Add INSTALL_PMPPC
Put each family of kernels on a separate line.

(matt)

Add a BUGS section to point out that the statistic "average" is an
average only of the current, minimum, and maximum values, and not a
running average of all displayed current values.

(pgoyette)

Zero is a valid value for some sensors so update statistics code to
handle that.

(pgoyette)

Document the naming convention.

(jym)

Be more consistent for event handler naming with block backend: it is
xbdback(4) rather than xbd(4), and use i for identifier separation
(like xvif(4)).

The name is not used outside from event counters (vmstat -i), so
should be transparent to Xen block scripts.

(jym)

use a simple counter as IV for AES-GMAC as suggested in RFC4543

(drochner)

fix tunnel encapsulation in ipsec6_process_packet() -- it is not
completely clean yet, but at least a v6-in-v6 tunnel works now

(drochner)

reindent ipsec6_process_packet() - whitespace changes only

(drochner)

SYMTAB_SPACE is decimal, so fix syntax error introduced by the previous.

(he)

Fix bad cut'n'paste in copyright. Pointed out by dyoung@

(bouyer)

Don't call psignal() without holding proc_lock. This is the cause of
the reboot of PR port-xen/45028
Now that Xen2 is gone, handle FPU context switches the same way as
amd64. This makes all tests in /usr/tests/lib/libc/ieeefp pass.
