Add tools/arm.subr to contain common subroutines used for

Parts of this were taken from disecting a previous BEAGLEBONE

Bug fixes found internally as detailed below:
1. While disabling interrupt the FW disables interrupts for only 16 vectors.
In case of Invader which supports 96 MSI-x vectors, some spurious interrupts
may come on other vectors even after interrupt disable. So, driver uses a flag
and ignores the spurious interrupts.
2. Reply queue depth is made double the number of commands supported by FW.
3. Misplaced interrupt enable code is now moved down in the OCR path.
4. Updated error handling code in OCR path.
5. Removed un-necessary print.

Driver calls mrsas_complete_cmd() to call mrsas_wakeup() for each MFI frame that was

userspace ioctl() system calls issued just before a kill adapter don't get stuck in

In OCR(Online Controller Reset) path, driver sets adapter state to

There will be a small window where IO will come from OS with old RAID map.
This patch will update adapter state to MEGASAS_HBA_OPERATIONAL,

Create std.arm and std.armv6 config files and include the right one from
each of the existing kernel configs. This gives a place to put config
that applies to the entire arch.
Add the ARM_NEW_PMAP option to std.armv6. This is working well in early
testing and it's time for wide exposure, but it's still nice to be able
to fall back to the old implementation for testing when a problem comes
along. Eventually the option and the old implementation will go away.
The opportunity now exists to move a whole lot of boilerplate from all the
arm kernel config files into std.arm*, but that's a commit for another day.

cp: Remove fts sorting.
In an attempt to improve performance, cp reordered directories first
(although the comment says directories last). This is not effective with new
UFS layout policies.
The sorting reorders multiple arguments passed to cp, which may be
undesirable.
Additionally, the comparison function does not induce a total order. Per
POSIX, this causes undefined behaviour in qsort().
NetBSD removed the sorting in 2009.
On filesystems that return directory entries in hash/btree order, sorting by
d_fileno before statting improves performance on large directories. However,
this can only be implemented in fts(3).

zfs: do not hold an extra reference on a root vnode while a filesystem is mounted
At present zfs_domount() acquires a reference on the filesystem's root vnode
and that reference is kept until zfs_umount.
The latter calls vflush(rootrefs = 1) to dispose of the extra reference.
There is no explanation of why that reference is kept - what problem it
solves or what behavior it improves.
Also, that logic is FreeBSD specific.
There is one real problem with that reference, though.
zfs recv -F may receive a full, non-incremental stream to a mounted filesystem.
In that case the received root object is likely to have a different z_gen
attribute value. Because of that, zfs_rezget will leave the previous root znode
and vnode disassociated from the actual object (z_sa_hdl == NULL).
Thus, future calls to VFS_ROOT() -> zfs_root() will produce a new vnode-znode
pair, while the old one will be kept alive by the outstanding reference.
So, the outstanding reference will not actually be for the new root vnode
(or, more precisely, vnodes - because a root vnode may be recycled and a newer
one can be created).
As a result, when vflush(rootrefs = 1) s called there will be two problems:
- a leaked reference on the old root vnode preventing a graceful unmount
- insufficient references on the actual root vnode leading to a crash upon
access to the vnode after it is destroyed by vgone() + vdrop()
The second issue will actually override the first one.

Copy new attribute types when linking. bfd will copy attributes as needed,
however it will fail to output them if the type is not set correctly. This
can happen when it finds an attribute it hasn't seen before, for example
when building shared objects it will use the attributes from crti.o, hwever
this file has no attributes set.
