      ahci: Gigabyte GA-MA69VM-S2 can't do 64bit DMA · 1b549dcb
      由 Tejun Heo 提交于 
      Gigabyte GA-MA69VM-S2 can't do 64bit DMA either.  It's yet unknown
whether recent BIOS fixes the problem.  Blacklist regardless of BIOS
revisions for now.

Sandor Bodo-Merle reported and provided the initial patch for this
issue.

      ahci: make ahci_asus_m2a_vm_32bit_only() quirk more generic · 03d783bf
      由 Tejun Heo 提交于 
      It turns out ASUS M2A-VM isn't the only one with the 32bit DMA
problem.  Make ahci_asus_m2a_vm_32bit_only() more generic using the
new dmi_get_date() and rename it to ahci_sb600_32bit_only().  Cut off
date is now pointed to by dmi_system_id->driver_data in "yyyymmdd"
format and it's now also allowed to be omitted.

      dmi: extend dmi_get_year() to dmi_get_date() · 3e5cd1f2
      由 Tejun Heo 提交于 
      There are cases where full date information is required instead of
just the year.  Add month and day parsing to dmi_get_year() and rename
it to dmi_get_date().

As the original function only required '/' followed by any number of
parseable characters at the end of the string, keep that behavior to
avoid upsetting existing users.

The new function takes dates of format [mm[/dd]]/yy[yy].  Year, month
and date are checked to be in the ranges of [1-9999], [1-12] and
[1-31] respectively and any invalid or out-of-range component is
returned as zero.

The dummy implementation is updated accordingly but the return value
is updated to indicate field not found which is consistent with how
other dummy functions behave.

      dmi: fix date handling in dmi_get_year() · 02c24fa8
      由 Tejun Heo 提交于 
      Year parsing in dmi_get_year() had the following two bugs.

* "00" is treated as invalid instead of 2000 because zero return from
  simple_strtoul() is treated as error.

* "0N" where N >= 8 is treated as invalid of 200N because the leading
  0 is considered to specify octal.

Fix the above two bugs by using endptr to detect invalid number and
forcing decimal.

      libata: unbreak TPM filtering by reorganizing ata_scsi_pass_thru() · bd30add8
      由 Tejun Heo 提交于 
      ata_scsi_pass_thru() was checking for input sanity and disallowed
commands while initializaing qc from scmd.  TPM filtering was added
right after protocol check at which point tf wasn't initialized
properly.  This means that TPM filtering has never really worked.

This patch fixes the bug by reorganizing ata_scsi_pass_thru() such
that qc is fully initialized before checking for invalid conditions
which is way less error prone.

Discovered while Thilo-Alexander Ginkel was trying debug patches for
bko#13416.

      sata_sis: convert to slave_link · 72fee382
      由 Tejun Heo 提交于 
      During introduction of slave_link, sata_sis slipped through the crack
and left with ad-hoc merged SCR access.  As SCR status was shared for
both the master and slave devices, when only one of the device is
online, libata EH would think both are online but would only get valid
device signature for the actually present one, which in turn trigger
the probing safety net mechanism and make EH retry causing large delay
during boot.  This patch converts sata_sis to slave_link mechanism.

This bug was reported by TAXI in bko#14075.
