tricky one: hisax sections
a) hisax_init_pcmcia() needs to be defined only if we have
CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared
__devinit.
b) HiSax_inithardware() can go __init
c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card():
checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card);
The problem with it is that
* hisax_cs_setup_card() is __devinit
* hisax_register() is not
* hisax_cs_setup_card() is a switch from hell, calling a lot of
setup_some_weirdcard() depending on card->typ. _These_ are also
__devinit.
However, in hisax_register() we have card->typ equal to
ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind
all that crap, just do nothing and return 2". So we add a
trimmed-down callback doing just that and passed to checkcard() by
hisax_register(). _This_ is non-init (we can stand the impact on
.text size).

toshiba_acpi: close race in toshiba_acpi driver
the toshiba ACPI driver will, in a failure case, free the rfkill state
before stopping the polling timer that would use this state. More interesting,
in the same failure case handling, it calls the exit function, which also
frees the rfkill state, but after stopping the polling.
If the race happens, a NULL pointer is passed to rfkill_force_state()
which then causes a nice dereference.
Fix the race by just not doing the too-early freeing of the rfkill state.

The faulting instruction is the storage key operation (iske) in
ptep_rcp_copy (called by pte_clear, called by unmap_vmas). iske
reads dirty and reference bit information for a physical page and
requires a valid physical address. Since we are in pte_clear, we
cannot rely on the pte containing a valid address. Fortunately we
dont need these information in pte_clear - after all there is no
mapping. The best fix is to remove the needless call to ptep_rcp_copy
that contains the iske.

The s390 implementation of sched_clock uses the store clock instruction and
subtracts jiffies_timer_cc.
jiffies_timer_cc is a local variable in arch/s390/kernel/time.c and only used
for sched_clock and monotonic clock. For historical reasons there is an offset
on that value. With todays code this offset is unnecessary. By removing that
offset we can get a sched_clock which returns the nanoseconds after time_init.
This improves CONFIG_PRINTK_TIME.
Since sched_clock is the only user, I have also renamed jiffies_timer_cc to
sched_clock_base_cc. In addition, the local variable init_timer_cc is redundant
and can be romved as well.

ACPI: thinkpad-acpi: fix fan sleep/resume path
This fixes a regression from v2.6.27, caused by commit
5814f737e1cd2cfa2893badd62189acae3e1e1fd, "ACPI: thinkpad-acpi:
attempt to preserve fan state on resume".
It is possible for fan_suspend() to fail to properly initialize
fan_control_desired_level as required by fan_resume(), resulting on
the fan always being set to level 7 on resume if the user didn't
touch the fan controller.
In order to get fan sleep/resume handling to work right:
1. Fix the fan_suspend handling of the T43 firmware quirk. If it is
still undefined, we didn't touch the fan yet and that means we have no
business doing it on resume.
2. Store the fan level on its own variable to avoid any possible
issues with hijacking fan_control_desired_level (which isn't supposed
to have anything other than 0-7 in it, anyway).
3. Change the fan_resume code to me more straightforward to understand
(although we DO optimize the boolean logic there, otherwise it looks
disgusting).
4. Add comments to help understand what the code is supposed to be
doing.
5. Change fan_set_level to be less strict about how auto and
full-speed modes are requested.

ACPI suspend: Blacklist boxes that require us to set SCI_EN directly on resume
Some Apple boxes evidently require us to set SCI_EN on resume
directly, because if we don't do that, they hung somewhere in the
resume code path. Moreover, on these boxes it is not sufficient to
use acpi_enable() to turn ACPI on during resume. All of this is
against the ACPI specification which states that (1) the BIOS is
supposed to return from the S3 sleep state with ACPI enabled
(SCI_EN set) and (2) the SCI_EN bit is owned by the hardware and we
are not supposed to change it.
For this reason, blacklist the affected systems so that the SCI_EN
bit is set during resume on them.
[NOTE: Unconditional setting SCI_EN for all system on resume doesn't
work, because it makes some other systems crash (that's to be
expected). Also, it is not entirely clear right now if all of the
Apple boxes require this workaround.]

parisc: fix bug in compat_arch_ptrace
Commit
81e192d6ce303b6792aa38ff35f41a1a7357f23a ("parisc: convert to

[<

The problem is that compat_arch_ptrace() enters with an addr value of
type compat_ulong_t and calls translate_usr_offset() to translate the
address offset into a struct pt_regs offset like this:
addr = translate_usr_offset(addr)
this means that any return value of translate_usr_offset() is stored
back as compat_ulong_t type into the addr variable.
But since translate_usr_offset() returns -1 for invalid offsets, addr
can now get the value 0xffffffff which then fails the next return-value
sanity check and thus the kernel tries to access invalid memory:
if (addr < 0)
break;
Fix this bug by modifying translate_usr_offset() to take and return
values of type compat_ulong_t, and by returning the value
"sizeof(struct pt_regs)" as an error indicator.
Additionally change the sanity check to check for return values
for >= sizeof(struct pt_regs).
This patch survived my compile and run-tests.

[CIFS] Do not attempt to close invalidated file handles
If a connection with open file handles has gone down
and come back up and reconnected without reopening
the file handle yet, do not attempt to send an SMB close
request for this handle in cifs_close. We were
checking for the connection being invalid in cifs_close
but since the connection may have been reconnected
we also need to check whether the file handle
was marked invalid (otherwise we could close the
wrong file handle by accident).

This patch fixes the wrong use of GPIO register offsets
in devices.c. To avoid further problems, use gpio_get_value
to return the NAND status instead of our own expanded code.
Also define the zero offset of the alternate function register to allow
consistent access.
