r327612: Invent new #defines for the biospci_{read,write}_config function

r327703: Define __dmadat after #include'ing ufsread.c.

r327704: Fix printf missing format variables warnings.

r327878: Add GUID for UEFI boot manager variables.

r327879: Report the boot order and where we are in that boot order.

r327881: Allow this file to be included

r328007: Fix booting on some arm64 systems after r327879 by fixing the call
to utf8_to_ucs2

r328029: When returning an error and freeing allocated memory from
ucs2_to_utf8, NULL the return pointer.

r328030: Check the return value from utf8_to_ucs2 instead of whether or not
uv is NULL.

r328031: Need to free uv after we're done using it.

r328061: utf8_to_ucs2() should check for malloc failure

r328156: stand: Move sections around to fix stand/ build with ld.lld on
armv7

r328169: Remove extra copy of bootinfo.c. It's a bit rotted copy of the one
in efi/loader.

r328288: Fix some resource leaks.

r328289: Don't leak memory when displaying help.

r328290: On malloc failure, be sure to close the include file that triggered
it.

r328291: getenv does not return tainted data in the boot loader. Attempt to
clue Coverity into that fact.

r328292: There's no tainted data here, tag it as such to avoid false
positives.

r328411: loader.efi: add missing EFI GUIDs

r328536: loader: support for mixed-endianness ELF/loader and POWER8

r328603: Add missing non-POWERPC case to give the scr value something
non-zero.

r328769: Centralize several variables.

r328779: Retire pnp.4th and the code needed only for 4th words used here.

r328780: These 4th words were an attempt to allow integration into the boot
loader scripts. However, that path won't be taken after all it
seems.

r328781: Remove pcibios forth support.

r328782: Now that we no longer conditionally compile some files outside of
ficl

r328783: Invent new LDR_INTERP for the loader interpreter to use.

r328806: We need more heap space to properly load newer powerpc kernels.

r328808: Implement strcoll as strcmp.

r328826: Make cross-endian loader changes apply only to powerpc

r328835: Fix regression introduced in r328806, preventing boot on many
platforms.

r328911: Ignore relocation tables for non-memory-resident sections.

r328986: Fix relative location of USB sources after recent move.

r328987: A more definitions to kernel emulation shim in order to build

While here, undo our libfdt hack of not including <stdlib.h> if we're
compiling _STANDALONE.

r324844: When building standalone, don't define errno. Let the definition from
stand.h override. This is similar to what we do in the kernel.

r326089: loader.efi: efipart does not recognize partitionless disks

r326090: net_parse_rootpath() has no parameters

r326143: Fix theoretical integer overflow issues. If the product here is

r326445: Fix random() and srandom() prototypes to match the standard.

r326446: Undefine _STANDALONE since this is test code.

r326448: Fix all warnings related to geli and ZFS support on x86.

r326484: Const poison the propname.

r326485: Delcare md_load in libofw.h. Make all prototypes match for ofw

r326486: Include machine/md_var to pick up __syncicache prototype.

r326487: Cast mdp (a vm_offset_t) to void * to match prototype.

r326488: e_entry can be smaller than a pointer. Cast it to an intptr_t

r326490: Declare our strange brand of main().

r326491: Disconnet ps3 from the build. There's too many warnings to fix.

r326492: Cast void * pointer to char * so the arg matches the %s format.

r326493: Provide a md_load64 prototype.

r326494: Mark two things as unused (since they are only sometimes used)

r326495: Now it's safe to bump WARNS to 1.

r326504: Switch to proper MK_LOADER_GELI tests.

r326507: increase maximum size of zfsboot

r326509: loader.efi: add note about iPXE into the efipart.c

r326584: When building standalone, include stand.h rather than the kernel

r326585: Include ficl.h before anything else

r326586: No need to include the userland md5.h, the kernel one is just fine.

r326587: Use the kernel relative paths, rather than the userland relative
paths

r326588: Need to include skein in the include path

r326589: Make sure we include the right path for skein.h

r326590: Prefer stdint.h to inttypes.h

r326591: This isn't NetBSD specific code. Include these for any kernel /

r326592: Don't inherit CFLAGS. This a specialized test program.

r326593: Stop building with the standard system headers.

r326594: Now that we offer a semi-sane standards-ish set of #include files,
stop hacking includes with sed.

r326600: Since this is contrib code, create an upstreamable version of my

r326616: dhcp_try_rfc1048() is not used any more

r326671: Avoid setting -Wno-tentative-definition-incomplete-type with gcc.

r326707: Add partial support signal.h functioanlity. Pull in

built standalone.

r326709: Provide implementations for iscntrl, ispunct and isgraph.

r326710: Put the files we're copying over into a few variables and clean
hings up.

r326711: Const poison a couple of interfaces.

r326712: Create interp class.

r326714: boot1.c needs EFI_ZFS_BOOT too, so add it globally.

r326855: Cargo cut a fix for the regressions r326585 caused.

r326856: Fix comments after bump in size.

r326858: Revert r326855: Cargo cut a fix for the regressions r326585 caused.

r326886: Panic in sbrk if setheap hasn't been called yet. This is preferable
o a mysterious crash

r326926: Move loader help file definitions to being 100% inside of
loader.mk.

r326927: libficl is only ever used in a loader (never a boot) program. Move
it.

r326960: Simplify things a little. The RETURN macro isn't required.

r326962: Hoist btx include stuff to i386/Makefile.inc

r326963: No need to use relative paths like this here.

r327351: Fix ubldr. uboot/lib uses defines for the loader.

r327453: Add a validbcd() routine that uses the bcd2bin_data[] array

r327390: Garbage-collect loader.ps3. It is currently disconnected from the
build and kboot replaces.

r328441: abort() should be marked __dead2 since it won't return.

r328448: Make exit() never return until host_exit can be written.

r328449: Tag unreachable places as such. I left the while (1); in place

r328612: Move strtold wrapper from strtol.c to its own strtold.c.
