rctl_string_to_rule could previously index below the zeroth element of
racct_types via the macro. Maybe it shouldn't use the macro on
RACCT_UNDEFINED. But given every other RACCT_ definition is non-negative, it
seems pretty easy to foot-shoot this one without the check.

The local of the same name would alias the global, but we didn't even include
the header that defines tsc_freq. Include it and rename the local.

Ordinarily, rctl_write_outbuf frees 'sb'. However, if we are in low memory
conditions we skip past the rctl_write_outbuf. In that case, free 'sb'.

R_Zalloc is essentially a malloc(M_NOWAIT) wrapper. It is possible that 'rnh'
failed to allocate, but 'rmh' succeeds. In that case, we bail out of
rn_inithead() but previously did not free 'rmh'.
Introduced in r287073 (projects/routing) / MFP r294706.

'lst' is allocated with 'n1' members. 'n' indexes 'lst'. So 'n == n1' is an
invalid 'lst' index. This is a follow-up to r296009.

This driver thinks that the NCT_MAX_PIN index is a valid index in a few places
(nct_attach() for-loop, as well as NCT_IS_VALID_PIN()). Allocate room for
NCT_MAX_PIN as an index, that is, NCT_MAX_PIN + 1 elements.

If we reached MAXMEMDOM, we would previously try to insert an additional
element and only detect overflow after causing (probably trivial) memory
overflow. Instead, detect the ndomain > MAXMEMDOM case before we write past
the end.

No functional change, only trivial cases are done in this sweep,
Drivers that can get further enhancements will be done independently.

2. grcdump can be taken at failure points by invoking bxe_grc_dump()
when trigger_grcdump sysctl flag is set. When grcdump is taken
grcdump_done sysctl flag is set.
3. grcdump_done can be monitored by the user to retrieve the grcdump.

had the same issue and handling of pointers, so let's change that too.

This add a bhnd device table mechanism that standardizes matching of
devices on the bhnd(4) bus, discovery of device quirk flags, and should
be pluggable into the new PNPINFO machinery.

To facilitate use by SoC implementors working with bhnd-inheriting fdt/nexus
drivers:
* Splits bhnd_bus method implementations into generic bus implementations
(bhnd_bus_generic) and generic bhnd(4) driver implementations (bhnd_generic)
* Simplifies bhnd resource handling, allowing bhnd bus implementations to
support bhnd resource activation by implementing the standard BUS_*
resource APIs and BHND_BUS_ACTIVATE_RESOURCE().

This adds support for specifying the address space used by a bridge child;
this will either be the bridged SoC address space, or the host address space
required by children that map non SoC-address ranges from the PCI BAR.
This is necessary to support SROM/OTP child devices that live directly
beneath the bhndb device and require access to host resources, instead
of the standard behavior of delegating access to the bridged SoC address
space.

Summary:
PowerPC Book-E SMP is currently broken for unknown reasons. Pull in
Semihalf changes made c2012 for e500mc/e5500, which enables booting SMP.
This eliminates the shared software TLB1 table, replacing it with
tlb1_read_entry() function.
This does not yet support ePAPR SMP booting, and doesn't handle resetting CPUs
already released (ePAPR boot releases APs to a spin loop waiting on a specific
address). This will be addressed in the near future by using the MPIC to reset
the AP into our own alternate boot address.
This does include a change to the dpaa/dtsec(4) driver, to mark the portals as
CPU-private.
Test Plan:
Tested on Amiga X5000/20 (P5020). Boots, prints the following
messages:
Adding CPU 0, pir=0, awake=1
Waking up CPU 1 (dev=1)
Adding CPU 1, pir=20, awake=1
SMP: AP CPU #1 launched
top(1) shows CPU1 active.

The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy.
Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks.
Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device.
The cache also implements limited read-ahead to increase performance.
To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache.
