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.
but add a second argument to it to indicate whether the TLB/caches need to be
flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).
With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.

Move the extern for cpu_reset_address to the same file.
Add cpu_reset_address_paddr.
Kill cpu_reset_v4_MMU_disable.
if cpu_reset_address is NULL, then the MMU will be disabled.

PMP support in integrated to the atabus layer.
struct ata_channel's ch_drive[] is not dynamically allocated, and ch_ndrive
(renamed to ch_ndrives) closely reflects the size of the ch_drive[] array.
Add helper functions atabus_alloc_drives() and atabus_free_drives()
to manage ch_drive[]/ch_ndrives.
Add wdc_maxdrives to struct wdc_softc so that bus front-end can specify
how much drive they really support (master/slave or single).
ata_reset_drive() callback gains a uint32_t *sigp argument which,
when not NULL, will contain the signature of the device being reset.
While there, some cosmetic changes:
- added a drive_type enum to ata_drive_datas, and stop encoding the
probed drive type in drive_flags (we were out of drive flags anyway).
- rename DRIVE_ATAPIST to DRIVE_ATAPIDSCW to better reflect what this
really is
- remove ata_channel->ata_drives, it's redundant with the pointer in
ata_drive_datas
- factor out the interpretation of SATA signatures in sata_interpet_sig()
propagate these changes to the ATA HBA drivers, and add support for PMP
to ahcisata(4) and siisata(4).
Thanks to:
- Protocase (http://www.protocase.com/) which provided a system
with lots of controllers, SATA PMP and drive slots
- Conservation Genomics Laboratory, Department of Biology, New Mexico State
University for hosting the above system
- Brook Milligan, who set up remote access and has been very responsive
when SATA cable move was needed
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.
<sys/systm.h> to the one file that did not already contain it.
This now means that physmem can be changed by updating systm.h and uvm_page.c
(excluding fixing printfs)
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.)
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:
1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.
2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.
I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.
