The reset_all variable name is misleading as this bit is also applicable to
open, close, and finish actions. So rename that variable to "all" and remove
the unnecessary mask operation that's already done earlier.

cast the all bit to a u16 before shiting it by 8 to avoid undefined

The taskfile protocol is a numeric value, and can not be ORed. Currently
this is harmless as the protocol is always zeroed before, but if it ever
has a non-zero value the ORing would create incorrect results.

Currently libata statically allows only 1-block (512-byte) payload
for each TRIM command. Each payload can carry 64 TRIM ranges since
each range requires 8 bytes.
It is silly to keep doing the calculation (512 / 8) in different
places. Hence, define the new ATA_MAX_TRIM_RNUM for the result.

Currently if a WRITE SAME (16) command is issued to the SATL with
"number of blocks" that is larger than the "Maximum write same length"
(which is the maximum number of blocks per TRIM command allowed in
libata, currently 65535 * 512 / 8 blocks), the SATL will accept the
command and translate it to a TRIM command with the upper limit.
However, according to SBC (as of sbc4r11.pdf), the "device server"
should terminate the command with "Invalid field in CDB" in that case.

To make it consistent with the recently added ata_mselect_control().
We probably shouldn't have the word "mode" in its name anyway, since
that's not the case for other ata_msense_*() / ata_mselect_*() either.

The bit should always be set to 1 when the requested version of
page is "changeable" because we've made it so in ata_mselect_control().
Also, it should always be set to 1 if ATA_DFLAG_D_SENSE is set (when
the requested version of page is "current" or "default").

According to the HPT366 data sheet, PCI config space dword 0x40-0x43
bits 11:8 specify the primary drive cmd_high_time, however,
currently just 3 bits of the 4 are being used because the mask
is 0x700 and not 0x0f00. Fix the mask, allowing for the 40MHz clock

The comment suggests we should be having an SPC-3 version descriptor
but the 0260h is the code for "SPC-2 (no version claimed)". Correct
it to 0300h so that it has the "SPC-3 (no version claimed)" descriptor.
Note that we are claiming SPC-3 version compatibility in the VERSION
field of the standard INQUIRY data. Therefore, I assume the typo was
on the code but not on the comment.

Without this fix, the DRA bit of the caching mode page would not
be updated when the read look-ahead feature is toggled (e.g. with
`smartctl --set`), but will only be until, for example, the write

Commit 856c466393 ("libata: support device-managed ZAC devices")
had the line that "bumps" the VERSION field in standard INQUIRY data
removed. Add it back and claim SPC-5 version compatibility, which
matches with the current version descriptor "SPC-5 (no version claimed)"
that is used for ZAC devices.

It does not make sense and is confusing to respond with "Invalid
field in CDB" while we have no support at all implemented for
FORMAT UNIT. It is decent to let it go to the default, which
will respond with "Invalid command operation code" instead.

The sysfs file for the libata error handling has multiple issues
in the way it prints time stamps:
* it prints a 9-digit nanosecond value using a %06lu format string,
which drops some leading zeroes
* it converts a 64-bit jiffes value to a timespec using
jiffies_to_timespec(), which takes a 'long' argument, so the
result is wrong after a jiffies overflow (49 days).
* we try to avoid using timespec because that generally overflows
in 2038, although this particular usage is ok.
This replaces the jiffies_to_timespec call with an open-coded
implementation that gets it right.
