sppp: Add BPF-based packet filtering for dial-on-demand and idle-timeout
Introduce active/dialing filtering using BPF to if_spppsubr.c. This allows
sync PPP interfaces (e.g. pppoe(4)) to control which traffic triggers
dial-on-demand or keeps idle connections alive.
This option is similar to PPP_FILTER.
sppp: use RUN_ONCE(9) to initialize keepalive related resources
to prevent panics during concurrent attach/detach
- Initialize keepalive resources (e.g. spppq_lock and keepalive_ch)
once using RUN_ONCE(9) instead of the first attach.
- Do not free these resources on sppp_detach
NOTE:
We should release these resources in sppp_subr_modcmd(), but module
unloading/cleanup is not implemented yet.
It has been observed in the wild that some individual instances of
ISP10[24]0 controllers don't seem to like getting a 64-bit DMA address
from our driver (at least, there seems to be some sort of incorrect
handling vis a vis the RQSTYPE_A64 message in isp_intr()).
Upon inspection, it was noted that in isp_pci_dmasetup(), the decision
to use RQSTYPE_T3RQS vs RQSTYPE_T2RQS was conditional on sizeof(bus_addr_t)
being larger than sizeof(uint32_t).
However, this isn't the correct predicate; instead, the choice should
be dependent on what the largest value that bus_addr_t will have. As
it happans, the PCI layer makes a distinction between 32-bit and 64-bit
DMA windows, and isp_pci's use of the regular "pa->pa_dmat" would ensure
that the DMA address always fits within 32-bits. Therefore, there was
never a reason to use RQSTYPE_T3RQS, regardless of the size of bus_addr_t.
As such, we tweak the code to depend explicitly on a new isp_use_dma64
flag, which is initialized by the bus front-end according to the DMA
window selection that's been made.

Support for the 21142/21143 internal NWay block is structured like a
PHY driver, but it was overlooked when the ifmedia/mii layer gained a
locking protocol. Update it to avoid a recursive mutex acquisition
that can occur if the autonegotiation completes (very) quickly.

Always use snprintf for MPI_EVENT_INTEGRATED_RAID output. Keep better
track of the amount that we've already printed and increase the max
length to handle all string combinations (even if they shouldn't happen).
From a suggestion by kre.
Move the text noting the 4Gb boot restriction from the BUGS section
to the main text and expand it, as it not restricted to UltraSPARC 1
and 2 machines.
Minor grammar fix whilst here.
gcc/arm: For -mtp=soft, ensure stack alignment even in leaves.
The option -mtp=soft, which is the default on earmv5, makes queries
to the thread pointer, for access to static (`initial-exec')
thread-local storage, go through the C runtime subroutine
__aeabi_read_tp. (For earmv>=6, we use the cp15 register via a
single instruction.)
Thus procedures which gcc thinks of as leaf procedures that use
__aeabi_read_tp are not really leaf procedures -- and even though
__aeabi_read_tp itself doesn't use the stack pointer at all,
resolving the symbol may take a detour through the dynamic linker,
which does rely on an aligned stack pointer.
Without this change, code like
__thread int x = 0;
int *
get_x(void)
