Use device_lookup() to locate device instances
Lock irq_lock around i915_error_wake_up in i915_error_work_func.
pull in opt_arm_debug.h for VERBOSE_INIT_ARM
Change puffs from hashlist to vcache.
- field "pa_nhashbuckets" of struct "puffs_kargs" becomes a no-op.
  and should be removed on the next protocol version bump.
Move the mct's interrupt from a shared SPI interrupt to a private PPI
interrupt so all possible cpus get them.
Add CMU PLL offsets
Add PLL registers and PLL conversion macros
Substract just one each time instead of the periods missed. This will create a
more even representation of missed interrupts.

Also fix typo
Fix ldd on LP64 platforms by splitting the symbol versioning stuff for
elf64 as well.
Make Linux io_mapping actually work.

Can't use bus_space_map/bus_space_unmap in interrupt context, where
Linux uses this io_mapping abstraction.  Instead, do uvm_km_alloc up
front and then use bus_space_mmap/pmap_kenter_pa to map it.

XXX Should bus_space_reserve the region (but that's x86-only for now).
XXX Should use direct map if possible.
XXX Should set an MTRR WC too in case of direct map or no PAT.
don't leave trailing backlashes on commands, just like gmake does. What does
POSIX have to say?
 Add Internal SERDES mode support newer than or equal to 82575.
Currently, it supports fiber device only. If you use 1000BaseT SFP module,
it won't work. We have to write code to read SFP ROM and set SGMII mode
if the module is copper.
Add comments to Exynos4 PLL registers and add Exynos5 PLL registers
Implement CPU speed control for Exynos4 and Exynos5 CPUs using APLL frequency
adjustment.
Make dk(4) discard from partition start, not from disk start.

Otherwise, anything mounted with `-o discard' will pretty quickly
munch itself up and barf up an unrecoverably corrupted file system!

XXX pullup to netbsd-7
Enter/leave flag is -w not -dw
tyop police
hack around an evergreen attach crash for now: provide a hard coded
name for the i2c.
