Since DTS from >= Linux 5.0 the slave address are relative to the parent
node address and aren't the full ones.
Check both so the cpsw driver can find the phy id.
r350229 changed the code to lookup the ti,hwmods property in the parent

to be also in the node itself so we can boot with an older DTB.

When a fusefs file system is mounted using the writeback cache, the cache
may still be bypassed by opening a file with O_DIRECT. When writing with
O_DIRECT, the cache must be invalidated for the affected portion of the
file. Fix some panics caused by inadvertently invalidating too much.

Nothing uses these anymore. They were for super small armv4 boards without
uboot. We removed armv4 support before 13.0, but neglected to garbage collect
this at the same time. Today, both flavors of armv5 kernels (mv and ralink) boot
via uboot which has its own compression scheme for boards that need it.
Note: OLDFILES has not been updated beacuse installkernel will move the whole

r346932 replaced a call to vn_bmap_seekhole() with a call to
ufs_bmap_seekdata(). Although vn_bmap_seekhole() locks the vnode,
ufs_bmap_seekdata() assumes it is already locked.
This patch adds locking of the vnode before the ufs_bmap_seekdata() call.
If the vn_lock() call fails, it returns EBADF since that is the normal
error returned when a file system is forced dismounted and is already
listed as an error return in the lseek(2) man page.

We want to allocate a contiguous memory block anywhere in memory, but
expressed this as having to be between 0 and 0xffffffff. This limits us

mapped above that address range.
Allow the full address range to be used for this allocation.

The timeout field in the CAPS register is defined to be 8 bits, so its type was
uint8_t. We recently started adding 1 to it to cope with rogue devices that
listed 0 timeout time (which is impossible). However, in so doing, other devices
that list 0xff (for a 2 minute timeout) were broken when adding 1
overflowed. Widen the type to be uint32_t like its source register to avoid the

Also, the loop in moa64_enter() was removed, as moea64_pvo_enter()

This commit is for the correct version. (The incorrect one had the order
of the last two entries reversed, due to my testing with copy_file_range
at 568 instead of 569.) This misordering should not have been a problem,
but is now fixed.
This patch adds support to the kernel for a Linux compatible
copy_file_range(2) syscall and the related VOP_COPY_FILE_RANGE(9).
This syscall/VOP can be used by the NFSv4.2 client to implement the
Copy operation against an NFSv4.2 server to do file copies locally on
the server.
The vn_generic_copy_file_range() function in this patch can be used
by the NFSv4.2 server to implement the Copy operation.
Fuse may also me able to use the VOP_COPY_FILE_RANGE() method.
vn_generic_copy_file_range() attempts to maintain holes in the output
file in the range to be copied, but may fail to do so if the input and
output files are on different file systems with different _PC_MIN_HOLE_SIZE
values.
Separate commits will be done for the generated syscall files and userland
changes. A commit for a compat32 syscall will be done later.

It turns out statistics accounting is very expensive in the pmap driver,
and doesn't seem necessary in the common case. Make this optional
behind a MOEA64_STATS #define, which one can set if they really need
statistics.
This saves ~7-8% on buildworld time on a POWER9.

turnstile_{lock,unlock}() were added for use in epoch. turnstile_lock()
returned NULL to indicate that the calling thread had lost a race and
the turnstile was no longer associated with the given lock, or the lock
owner. However, reader-writer locks may not have a designated owner,
in which case turnstile_lock() would return NULL and
epoch_block_handler_preempt() would leak spinlocks as a result.
Apply a minimal fix: return the lock owner as a separate return value.

Commit text by Jake:
If a driver's IFDI_ATTACH_PRE function fails, the iflib_device_register
function will free the ctx pointer. However, it does not reset the
device softc pointer to NULL.
This will result in memory corruption as a future access to the now
invalid pointer will corrupt memory that is later allocated on top of
the same memory location.
The iflib_device_deregister function correctly resets the softc pointer
by using device_set_softc().
This clears up the invalid dangling pointer and prevents memory
corruption that could lead to a panic or undefined behavior if the
device's driver failed to attach.
