The src_base and dst_base fields in apei_exec_context are physical
address, so they should be ioremaped before being used in ERST
MOVE_DATA instruction.

commit 934231de706d2579fae14f5857fcd8de991009ff fixes an unbalanced
CONFIG_ACPI_PROCFS code block during module initialisation. This
patch fixes similar issue but for the module exit.

Section 4.7.3.1.1 (PM1 Status Registers) of version 4.0 of
the ACPI spec concerning PCIEXP_WAKE_STS points out in
in the final note field in table 4-11 that if this bit is
set to 1 and the system is put into a sleeping state then
the system will not automatically wake.
This bit gets set by hardware to indicate that the system
woke up due to a PCI Express wakeup event, so clear it during
acpi_hw_clear_acpi_status() calls to enable subsequent
resumes to work.

Commit 2a6b69765ad794389f2fc3e14a0afa1a995221c2 (ACPI: Store NVS
state even when entering suspend to RAM) changed the ACPI suspend
to RAM code so that the NVS memory area is always unconditionally
saved during suspend and restored during resume, since some systems
evidently need that for the suspend-resume to work on them. However,
it turned out that this change broke suspend-resume on a few systems,
so commit 72ad5d77fb981963edae15eee8196c80238f5ed0 (ACPI / Sleep:
Allow the NVS saving to be skipped during suspend to RAM) introduced
the acpi_sleep=nonvs command line switch to allow their users to
work around this issue. To keep track of the systems that require
this workaround and to make the life of their users slightly easier
blacklist them in acpisleep_dmi_table[].

ACPI batteries can report in units of either current or energy. Right
now we expose the current_now file even if the battery is reporting
energy units, resulting in a file that should contain mA instead
containing mW. Don't expose this value unless the battery is reporting
current.

platform_data in hest_parse_ghes() is used for saving the address of entry
information of erst_tab. When the device is failed to be added, platform_data
will be freed by platform_device_put(). But the value saved in platform_data
should not be freed here. If it is done, it will make system panic.
So I think platform_data should save the address of allocated memory
which saves entry information of erst_tab.
This patch fixed it and I confirmed it on x86_64 next-tree.
v2:
Transport the pointer of hest_hdr to platform_data using
platform_device_add_data()

After we ioremap() a new region, we call __acpi_try_ioremap() to
see whether another thread has already mapped the same region.
This check clobbers "vaddr", so compute the return value of

Modified the unsuitable description of patch.

On Huang Ying's machine:
erst_tab->header_length == sizeof(struct acpi_table_einj)
but Yinghai reported that on his machine,
erst_tab->header_length == sizeof(struct acpi_table_einj) -
sizeof(struct acpi_table_header)
To make erst table size checking code works on all systems, both
testing are treated as PASS.
Same situation applies to einj_tab->header_length, so corresponding
table size checking is changed in similar way too.
v2:
- Treat both table size as valid

Avoid TLB flush IPIs for the cores in deeper c-states by voluntary leave_mm()
before entering into that state. CPUs tend to flush TLB in those c-states
anyways.
acpi_idle does this with C3-type states, but it was not caried over
when intel_idle was introduced. intel_idle can apply it
to C-states in addition to those that ACPI might export as C3...

When the Lenovo Ideapad S10-3 is booted with HT enabled,
it hits a boot hang in the intel_idle driver.
This occurs when entering ATM-C4 for the first time,
unless BM_STS is first cleared.
acpi_idle doesn't see this because it first checks
and clears BM_STS, but it would hit the same hang
if that check were disabled.

When using simultaneously the two DMA channels on a same engine, some
transfers are never completed. For example, an endless lock can occur
while writing heavily on a RAID5 array (with async-tx offload support
enabled).
Note that this issue can also be reproduced by using the DMA test
client.
On a same engine, the interrupt cause register is shared between two
DMA channels. This patch make sure that the cause bit is only cleared
for the requested channel.

In max8925_irq_sync_unlock(), irq control bit is set at the same time.
Zero means enabling irq, and one means disabling irq.
The original code is:
irq_chg[0] &= irq_data->enable;
It should be changed to:
irq_chg[0] &= ~irq_data->enable;
Otherwise, irq control bit is mess.

libata depends on scsi_host_template for module reference counting and
sht's should be owned by each low level driver. During libahci split,
the sht was left with libahci.ko leaving the actual low level drivers
not reference counted. This made ahci and ahci_platform always
unloadable even while they're being actively used.
Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for
each low level ahci driver.
stable: only applicable to 2.6.35.

Commit e40cc4bdfd4b89813f072f72bd9c7055814d3f0f introduced
a build breakage if CONFIG_SMP is undefined. This commit
fixes the problem.
This fix is only a workaround. For a real fix, cpu_sibling_mask() should
be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be
included directly. This fix is currently not possible because asm/smp.h defines
cpu_sibling_mask() unconditionally and is included directly from many source
files.

When the interface is up, using ethtool breaks it because:
a) link is put down but media_timer interval is not shortened to NO_LINK
b) rxtx is stopped but not restarted
Also manual 10baseT-HD (and probably FD too - untested) mode does not work -
the link is forced up, packets are transmitted but nothing is received.
Changing CSR14 value to match documentation (not disabling link check) fixes this.

This patch (commit 690a1f2002a3091bd18a501f46c9530f10481463) added a
new call site for acpi_set_WOL() without checking that the function is
actually suitable to be called via
vortex_set_wol+0xcd/0xe0 [3c59x]
dev_ethtool+0xa5a/0xb70
dev_ioctl+0x2e0/0x4b0
T.961+0x49/0x50
sock_ioctl+0x47/0x290
do_vfs_ioctl+0x7f/0x340
sys_ioctl+0x80/0xa0
system_call_fastpath+0x16/0x1b
i.e. outside of code paths run when the device is not yet enabled or
already disabled. In particular, putting the device into D3hot is a
pretty bad idea when it was already brought up.
Furthermore, all prior callers of the function made sure they're
actually dealing with a PCI device, while the newly added one didn't.
In the same spirit, the .get_wol handler shouldn't indicate support
for WOL for non-PCI devices.

Freeing netdev without free_netdev() leads to net, tx leaks.
I might lead to dereferencing freed pointer.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
@@
struct net_device* dev;
@@
-kfree(dev)
+free_netdev(dev)
