iscsi_ibft: filter null v4-mapped v6 addresses
I've had reports of UEFI platforms failing iSCSI boot in various
configurations, that ended up being caused by network initialization
scripts getting tripped up by unexpected null addresses (0.0.0.0) being
reported for gateways, dhcp servers, and dns servers.
The tianocore EDK2 iSCSI driver generates an iBFT table that always uses
IPv4-mapped IPv6 addresses for the NIC structure fields. This results
in values that are "not present or not specified" being reported as
::ffff:0.0.0.0 rather than all zeros as specified.
The iscsi_ibft module filters unspecified fields from the iBFT from
sysfs, preventing userspace from using invalid values and making it easy
to check for the presence of a value. This currently fails in regard to
these mapped null addresses.
In order to remain consistent with how the iBFT information is exposed,
we should accommodate the behavior of the tianocore iSCSI driver as it's
already in the wild in a large number of servers.
Tested under qemu using an OVMF build of tianocore EDK2.

Writing to a file is supposed to return the number of bytes written.
Returning zero unfortunately causes bash to constantly spin trying
to write to the sysfs file, to such an extent that even ^c and ^z
have no effect. The only way out of that is to kill the shell and
log back in. This isn't nice behaviour.
Fix it by returning the number of characters written to sysfs files.

On some v7 devices (e.g. Lenovo-E550) the deltas reported are typically
only in the 0-1 range dividing this by 2 results in a range of 0-0.
And even for v7 devices where this does not lead to making the trackstick
entirely unusable, it makes it twice as slow as before we added v7 support
and were using the ps/2 mouse emulation of the dual point setup.
If some kind of generic slowdown is actually necessary for some devices,
then that belongs in userspace, not in the kernel.

In the functions compat_get_bitmap() and compat_put_bitmap() the
variable nr_compat_longs stores how many compat_ulong_t words should be
copied in a loop.
The copy loop itself is this:
if (nr_compat_longs-- > 0) {
if (__get_user(um, umask)) return -EFAULT;
} else {
um = 0;
}
Since nr_compat_longs gets unconditionally decremented in each loop and
since it's type is unsigned this could theoretically lead to out of
bounds accesses to userspace if nr_compat_longs wraps around to
(unsigned)(-1).
Although the callers currently do not trigger out-of-bounds accesses, we
should better implement the loop in a safe way to completely avoid such
warp-arounds.

The driver worked around an error in the MAYA44 USB(+)'s mixer unit
descriptor by aborting before parsing the missing field. However,
aborting parsing too early prevented parsing of the other units
connected to this unit, so the capture mixer controls would be missing.
Fix this by moving the check for this descriptor error after the parsing
of the unit's input pins.

We used to read file_handle twice. Once to get the amount of extra
bytes, and once to fetch the entire structure.
This may be problematic since we do size verifications only after the
first read, so if the number of extra bytes changes in userspace between
the first and second calls, we'll have an incoherent view of
file_handle.
Instead, read the constant size once, and copy that over to the final
structure without having to re-read it again.

cpumask_test_cpu() doesn't take volatile, unlike the obsoleted
cpu_isset. The only place ia64 really cares is the spin waiting for a

The early_idt_handlers asm code generates an array of entry
points spaced nine bytes apart. It's not really clear from that
code or from the places that reference it what's going on, and
the code only works in the first place because GAS never
generates two-byte JMP instructions when jumping to global
labels.
Clean up the code to generate the correct array stride (member size)
explicitly. This should be considerably more robust against
screw-ups, as GAS will warn if a .fill directive has a negative
count. Using '. =' to advance would have been even more robust
(it would generate an actual error if it tried to move
backwards), but it would pad with nulls, confusing anyone who
tries to disassemble the code. The new scheme should be much
clearer to future readers.
While we're at it, improve the comments and rename the array and
common code.
Binutils may start relaxing jumps to non-weak labels. If so,
this change will fix our build, and we may need to backport this
change.

This reverts commit 5fc872c732.
The DMA-API does not strictly require that the memory
returned by dma_alloc_coherent is zeroed out. For that
another function (dma_zalloc_coherent) should be used. But
all other x86 DMA-API implementation I checked zero out the
memory, so that some drivers rely on it and break when it is
not.
It seems the (driver-)world is not yet ready for this
change, so revert it.
