which belongs to the cache kmalloc-512 of size 512. The "page_address(sg_page(scsi_sglist(scmd)))"
maybe from sg_scsi_ioctl function "buffer" which allocated by kzalloc, so "buffer"

This also looks completely buggy on highmem systems and really needs to use a
kmap_atomic. --Christoph Hellwig
To address above bugs, Paolo Bonzini advise to simpler to just make a char array
of size CACHE_MPAGE_LEN+8+8+4-2(or just 64 to make it easy), use sg_copy_to_buffer
to copy from the sglist into the buffer, and workthere.

commit b5292111de9bb70cba3489075970889765302136 upstream.
Commit 130f4caf145c ("libata: Ensure ata_port probe has completed before
detach") may cause system freeze during suspend.
Using async_synchronize_full() in PM callbacks is wrong, since async
callbacks that are already scheduled may wait for not-yet-scheduled
callbacks, causes a circular dependency.
Instead of using big hammer like async_synchronize_full(), use async
cookie to make sure port probe are synced, without affecting other
scheduled PM callbacks.

There is also refcount issue, as well:
WARNING: CPU: 1 PID: 1 at lib/refcount.c:28 refcount_warn_saturate+0xf8/0x170
The issue is that we make an erroneous extra call to scsi_host_put()
for that host:
So in ahci_init_one()->ata_host_alloc_pinfo()->ata_host_alloc(), we setup
a device release method - ata_devres_release() - which intends to release
the SCSI hosts:
static void ata_devres_release(struct device *gendev, void *res)
{
...
for (i = 0; i < host->n_ports; i++) {
struct ata_port *ap = host->ports[i];
if (!ap)
continue;
if (ap->scsi_host)
scsi_host_put(ap->scsi_host);
}
...
}
However in the ata_scsi_add_hosts() error path, we also call
scsi_host_put() for the SCSI hosts.
Fix by removing the the scsi_host_put() calls in ata_scsi_add_hosts() and
leave this to ata_devres_release().

commit 10a663a1b15134a5a714aa515e11425a44d4fdf7 upstream.
device_shutdown() called from reboot or power_shutdown expect
all devices to be shutdown. Same is true for even ahci pci driver.
As no ahci shutdown function is implemented, the ata subsystem
always remains alive with DMA & interrupt support. File system
related calls should not be honored after device_shutdown().
So defining ahci pci driver shutdown to freeze hardware (mask
interrupt, stop DMA engine and free DMA resources).

commit 8385d756e114f2df8568e508902d5f9850817ffb upstream.
ata_qc_complete_multiple() is called with a mask of the still active
tags.
mv_sata doesn't have this information directly and instead calculates
the still active tags from the started tags (ap->qc_active) and the
finished tags as (ap->qc_active ^ done_mask)
Since 28361c40368 the hw_tag and tag are no longer the same and the
equation is no longer valid. In ata_exec_internal_sg() ap->qc_active is
initialized as 1ULL << ATA_TAG_INTERNAL, but in hardware tag 0 is
started and this will be in done_mask on completion. ap->qc_active ^
done_mask becomes 0x100000000 ^ 0x1 = 0x100000001 and thus tag 0 used as
the internal tag will never be reported as completed.
This is fixed by introducing ata_qc_get_active() which returns the
active hardware tags and calling it where appropriate.
This is tested on mv_sata, but sata_fsl and sata_nv suffer from the same
problem. There is another case in sata_nv that most likely needs fixing
as well, but this looks a little different, so I wasn't confident enough
to change that.

commit 1a3d78cb6e20779a19388315bd8efefbd8d4a656 upstream.
Set AHCI_HFLAG_DELAY_ENGINE for the BCM7425 AHCI controller thus making
it conforming to the 'strict' AHCI implementation which this controller
is based on.
This solves long link establishment with specific hard drives (e.g.:
Seagate ST1000VM002-9ZL1 SC12) that would otherwise have to complete the
error recovery handling before finally establishing a succesful SATA
link at the desired speed.
We re-order the hpriv->flags assignment to also remove the NONCQ quirk
since we can set the flag directly.

commit bf0e5013bc2dcac205417e1252205dca39dfc005 upstream.
The downstream implementation of ahci_brcm.c did contain clock
management recovery, but until recently, did that outside of the
libahci_platform helpers and this was unintentionally stripped out while
forward porting the patch upstream.
Add the missing clock management during recovery and sleep for 10
milliseconds per the design team recommendations to ensure the SATA PHY
controller and AFE have been fully quiesced.

commit c0cdf2ac4b5bf3e5ef2451ea29fb4104278cdabc upstream.
The AHCI resources management within ahci_brcm.c is a little
convoluted, largely because it historically had a dedicated clock that
was managed within this file in the downstream tree. Once brough
upstream though, the clock was left to be managed by libahci_platform.c
which is entirely appropriate.
This patch series ensures that the AHCI resources are fetched and
enabled before any register access is done, thus avoiding bus errors on
platforms which clock gate the controller by default.
As a result we need to re-arrange the suspend() and resume() functions
in order to avoid accessing registers after the clocks have been turned
off respectively before the clocks have been turned on. Finally, we can
refactor brcm_ahci_get_portmask() in order to fetch the number of ports
from hpriv->mmio which is now accessible without jumping through hoops
like we used to do.
The commit pointed in the Fixes tag is both old and new enough not to
require major headaches for backporting of this patch.

This reverts commit 6bb86fefa086faba7b60bb452300b76a47cde1a5
("libahci_platform: Staticize ahci_platform_<en/dis>able_phys()") we are
going to need ahci_platform_{enable,disable}_phys() in a subsequent

With KASAN also enabled, we may also get many use-after-free reports.
The issue is that when CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, we may
attempt to detach the ata_port before it has been probed.
This is because the ata_ports are async probed, meaning that there is no
guarantee that the ata_port has probed prior to detach. When the ata_port
does probe in this scenario, we get all sorts of issues as the detach may
have already happened.
Fix by ensuring synchronisation with async_synchronize_full(). We could
alternatively use the cookie returned from the ata_port probe
async_schedule() call, but that means managing the cookie, so more
complicated.

Commit c312ef176399 "libata/ahci: Drop PCS quirk for Denverton and
beyond" got the polarity wrong on the check for which board-ids should
have the quirk applied. The board type board_ahci_pcs7 is defined at the
end of the list such that "pcs7" boards can be special cased in the
future if they need the quirk. All prior Intel board ids "<
board_ahci_pcs7" should proceed with applying the quirk.

[ Upstream commit c312ef176399e04fc5f7f2809d9a589751fbf6d9 ]
The Linux ahci driver has historically implemented a configuration fixup
for platforms / platform-firmware that fails to enable the ports prior
to OS hand-off at boot. The fixup was originally implemented way back
before ahci moved from drivers/scsi/ to drivers/ata/, and was updated in
2007 via commit 49f290903935 "ahci: update PCS programming". The quirk
sets a port-enable bitmap in the PCS register at offset 0x92.
This quirk could be applied generically up until the arrival of the
Denverton (DNV) platform. The DNV AHCI controller architecture supports
more than 6 ports and along with that the PCS register location and
format were updated to allow for more possible ports in the bitmap. DNV
AHCI expands the register to 32-bits and moves it to offset 0x94.
As it stands there are no known problem reports with existing Linux
trying to set bits at offset 0x92 which indicates that the quirk is not
applicable. Likely it is not applicable on a wider range of platforms,
but it is difficult to discern which platforms if any still depend on
the quirk.
Rather than try to fix the PCS quirk to consider the DNV register layout
instead require explicit opt-in. The assumption is that the OS driver
need not touch this register, and platforms can be added with a new
boad_ahci_pcs7 board-id when / if problematic platforms are found in the
future. The logic in ahci_intel_pcs_quirk() looks for all Intel AHCI
instances with "legacy" board-ids and otherwise skips the quirk if the
board was matched by class-code.

[ Upstream commit 2d7271501720038381d45fb3dcbe4831228fc8cc ]
For passthrough requests, libata-scsi takes what the user passes in
as gospel. This can be problematic if the user fills in the CDB
incorrectly. One example of that is in request sizes. For read/write
commands, the CDB contains fields describing the transfer length of
the request. These should match with the SG_IO header fields, but
libata-scsi currently does no validation of that.
Check that the number of blocks in the CDB for passthrough requests
matches what was mapped into the request. If the CDB asks for more
data then the validated SG_IO header fields, error it.

[ Upstream commit ca156e006add67e4beea7896be395160735e09b0 ]
ZAC support added sense data requesting on error for both ZAC and ATA
devices. This seems to cause erratic error handling behaviors on some
SSDs where the device reports sense data availability and then
delivers the wrong content making EH take the wrong actions. The
failure mode was sporadic on a LITE-ON ssd and couldn't be reliably
reproduced.
There is no value in requesting sense data from non-ZAC ATA devices
while there's a significant risk of introducing EH misbehaviors which
are difficult to reproduce and fix. Let's do the sense data dancing
only for ZAC devices.

ata_host_alloc() can only fail due to memory allocation failures.
Hence there is no need to print a message, as the memory allocation core
code already takes care of that.

ep93xx does not have a proper pinctrl driver, but does things
ad-hoc through mach/platform.h, which is also used for setting
up the boards.
To avoid using mach/*.h headers completely, let's move the interfaces
into include/linux/soc/. This is far from great, but gets the job
done here, without the need for a proper pinctrl driver.

Pull SCSI updates from James Bottomley:
"This is mostly update of the usual drivers: arcmsr, qla2xxx, lpfc,
hisi_sas, target/iscsi and target/core.
Additionally Christoph refactored gdth as part of the dma changes. The
major mid-layer change this time is the removal of bidi commands and
with them the whole of the osd/exofs driver and filesystem. This is a
major simplification for block and mq in particular"
