failed because we failed to acquire some resource needed to initiate
the pageout (such as failing to lock an indirect buffer) rather than
a hard i/o error. in this case we just want to reactivate the page(s)
so that we'll try to write them again later.
while I'm here, clean up some DIAGNOSTIC code.
- in genfs_getpages(), unbusy any pages that we don't free in the error path.
- in genfs_putpages(), if we get a bmap error, record that in the master buf.

Due to the StrongARM support code in the cpu_reset() MC-function,
an instruction was executed to drain the write back buffer on StrongARM
processors (might even be armv4+).
Since ARM{6,7} don't recognize this instruction they will either except
for an illegal instruction on this or have undefined behaviour resulting
in an endless illegal instruction/data abort/reset behaviour.
The fix contains a flag that signals if the WB flush should be executed
or not for the detected processor.

Don't allocate one large io range, this fails about every time on real
pcmcia buses (not attached to pci/cardbus bridges) because of other
devices interfering in that range. Use the bogusly small region for
now, which works purely by chance (map granularity) on cardbus bridges
too (more or less).
XXX - make this map three different, small regions after layer1 <-> layer2
XXX interface has been brought in shape.
blank. In this case, we delete all non-LARVAL SAs that match the
src/dst/protocol. This is particularly useful in IKE INITIAL-CONTACT
processing. Idea from Bill Sommerfeld <sommerfeld@east.sun.com>, who
implemented it in post-Solaris8.
OFW_PCI_PHYS_HI_DEVICE() - extract PCI device from phys_hi
OFW_PCI_PHYS_HI_FUNCTION() - extract PCI function from phys_hi
and the definition of `struct ofw_pci_register'.
Remove duplicate prototype for i386_{set,get}_ldt() from sys_machdep.c.
Change i386_iopl() and i386_{set,get}_{ldt,ioperm}() to take a second
argument of "void *" instead of "char *", for consistency with other syscalls.
to recode Unicode names to other representation, like encoding form
or national character/code sets. This replaces the ugly NTFS_U28() hack.
Use these hooks to encode the filenames to UTF-8.
arm32/arm32/machdep.c into arm/arm/sig_machdep.c, merging and ANSIfying in
the process.
The code is based on the arm32 version, so I don't think anything should break
there.
isp_iid_set/isp_iid for fibre channel- this is because we now
fake a port database entry for ourselves. Add the additional loop
states between LOOP_PDB_RCVD and LOOP_READY.
Change and comment on a wad of Fibre Channel isp_control functions.
Change and comment on some of the ISPASYNC Fibre Channel events.
Add was_fabric_dev/fabric_dev tags to our local FC database structure
(so we can see rapidly whether something was a fabric device but is
now gone).
Add a tag which says what role this adapter should take. It can take
on the value of None, Target, Initiator or Both. None is useful for
warm failover purposes. Remove the ISP_CFG_NOINIT silliness since
a role of "None" does this.
Add a isp_lastmbxcmd tag to store the opcode for the last mailbox
command used.
to report the mailbox command that times out. Fix isp_unswizzle_sns_rsp
which for reasons *I* find obscurer just doesn't work correctly on sparc64
with words past 128. I have no idea why this *does* work on SparcLinux.
and depending on role, make sure link is up, scan the fabric (if we're
connected to a fabric), scan the local loop (if appropriate), merge
the results into the local port database then, check once again
to make sure we have f/w at FW_READY state and the the loopstate
is LOOP_READY.
Remove ISP2100_FABRIC defines- we always handle fabric now. Insert
isp_getmap helper function (for getting Loop Position map). Make
sure we (for our own benefit) mark req_state_flags with RQSF_GOT_SENSE
for Fibre Channel if we got sense data- the !*$)!*$)~*$)*$ Qlogic
f/w doesn't do so. Add ISPCTL_SCAN_FABRIC, ISPCTL_SCAN_LOOP, ISPCTL_SEND_LIP,
and ISPCTL_GET_POSMAP isp_control functions. Correctly send async notifications
upstream for changes in the name server, changes in the port database, and
f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event.
When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol
Module) and FBM (Fibre Buffer Modules). Also remember to clear the
semaphore registers. Tell the RISC processor to not halt on FPM
parity errors.
Finally, use a new tag in the softc to store the opcode for the
last mailbox command used so we can report which opcode timed
out.
Major stuff:
Quite massively redo how we handle Loop events- we've now added several
intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us
a lot finer control about how we scan fabric, whether we go further
than scanning fabric, how we look at the local loop, and whether we
merge entries at the level or not. This is the next to last step for
moving managing loop state out of the core module entirely (whereupon
loop && fabric events will simply freeze the command queue and a thread
will run to figure out what's changed and *it* will re-enable the queu).
This fine amount of control also gets us closer to having an external
policy engine decide which fabric devices we really want to log into.
Throw out the ISP_CFG_NOINIT silliness and instead go to the use of
adapter 'roles' to see whether one completes initialization or not
(mostly for Fibre Channel). The ultimate intent, btw, of all of this
is to have a warm standby adapter for failover reasons. Because
we do roles now, setting of Target Capable Class 3 service parameters
in the ICB for the 2x00 cards reflects from role. Also, in isp_start,
if we're not supporting an initiator role, we bounce outgoing commands
with a Selection Timeout error. Also clean out the TOGGLE_TMODE
goop for FC- there is no toggling of target mode like there is
for parallel SCSI cards.
Do more cleanup with respect to using target ids 0..125 in F-port
topologies. Also keep track of things which *were* fabric devices
so that when you rescan the fabric you can notify the outer layers
when fabric devices go away.
Only force a LOGOUT for fabric devices if they're still logged in
(i.e., you cat their Port Database entry. Clean up the Get All Next
scanning.
a flag that determines whether or not wired mapping should be removed.
pmap_collect() calls pmap_do_remove() without this flag, and pmap_remove()
calls with it.
Pointed out on port-mac68k with suggested fix from chs.
scan of all directory entries; the mangled file name we return to
userland on getdents(2) may end up being unsearchable otherwise
This change is useful even through we will soon change to encode the
NTFS file names to utf-8 - we want to support recoding of filenames to
national 8bit charsets eventually.
while here, remove some unnecessary casts, change NTFS_U28() macro so that
the mangled filename doesn't contain control characters and use malloc()/free()
instead MALLOC()/FREE() for rdbuf buffer
when error is ERESTART. otherwise, user process will re-issue syscall
with broken system call number and get SIGSYS signal and terminate.
