instead of "pciide", and check one layer farther up in the device hierarchy
for the scsipidev device.
From Manuel Bouyer, tested by me on a up1500 (identical changes to other
ide-booting code).
mv MNT_GONE, MNT_UNMOUNT and MNT_WANTRDWR to this field
additonally add mnt_writeopcountupper and mnt_writeopcountlower fields
in preparation for pending write suspension support work
bump kernel version to 1.6ZD
"/usr/include/machine/varargs.h") by a stub include file which will
emit an error if GCC 3.3 or newer is used and include "machine/varargs.h"
otherwise.
Based on a suggestion by Richard Earnshaw. This fixes PR toolchain/22888
by myself.
first three bytes to determine how much of the BPB to preserve.
Supported values:
eb 3c 90 FAT16 BPB
eb 58 90 FAT32 BPB
(anything else) don't preserve any BPB
This is because the BPB is generally only the FAT16 one except in the
bootxx_msdos case, where it's the larger FAT32 one.
(Note: memcmp/memset improvements also benefit non-Xscale).
memcmp() - Compare 32-bits at a time if possible. Special-case 6-byte
comparisons, for the benefit of the network stack.
memset() - More loop unrolling, plus use of 'strd' instruction,
bzero() results in > 100% speedup on Xscale.
memcpy() - Big-endian support, unrolled loops, 'strd/pld', plus special-
cases for very common length/alignment combinations.
Benchmarks show ~50% improvment on Xscale.
memmove() - Big-endian support. Use fast memcpy(), above, if the regions
bcopy() don't overlap. Otherwise unchanged
XXX: The Xscale optimisations are not enabled by default, unless /etc/mk.conf
XXX: has the right compiler options. The intention is to pull them in via

- Use the "clz" instruction to pick a run-queue, instead of using the
ffs-by-table-lookup method.
- Use strd instead of stmia where possible.
- Use multiple ldr instructions instead of ldmia where possible.
