When battery is hot-added, we should not invoke power_supply_changed
in acpi_battery_notify, because it has been invoked in acpi_battery_update,
and battery->bat.changed_work is queued in keventd already.

Folklore suggested that such systems existed
in the pre-history of ACPI.
However, we removed the SCI_EN polling loop from
acpi_hw_set_mode() in b430acbd7c4b919886fa7fd92eeb7a695f1940d3
because it delayed resume by 3 seconds on boxes
that refused to set SCI_EN.
Matthew removed the call to acpi_enable() from
the suspend resume path.
James found a modern system that still needs to be polled
upon boot.
So here we restore the workaround, except that we
put it in acpi_enable() rather than the low level
acpi_hw_set_mode().

The commit 5d554a7bb06 (ACPI: processor: add internal
processor_physically_present()) is broken on uniprocessor (UP)
configurations, as acpi_get_cpuid() will always return -1.
We use the value of num_possible_cpus() to tell us whether we got
an invalid cpuid from acpi_get_cpuid() in the SMP case, or if
instead, we are UP, in which case num_possible_cpus() is #defined
as 1.
We use num_possible_cpus() instead of num_online_cpus() to
protect ourselves against the scenario of CPU hotplug, and we've
taken down all the CPUs except one.
Thanks to Jan Pogadl for initial report and analysis and Chen
Gong for review.

namespaces.
This fixes the regression in 2.6.35-rcX where bluetooth network devices
would fail to be deleted from sysfs, causing their destruction and
recreation to fail. In addition this fixes the mac80211_hwsim driver
where it would leave around sysfs files when the driver was removed.
This problem is discussed at
https://bugzilla.kernel.org/show_bug.cgi?id=16257
The reason for the regression is that the network namespace support
added to sysfs expects and requires that network devices be put in
directories that can contain only network devices.
Today get_device_parent almost provides that guarantee for all class
devices, except for a specific exception when the parent of a class
devices is a class device. It would be nice to simply remove that
arguably incorrect special case, but apparently the input devices depend
on it being there. So I have only removed it for class devices with
network namespace support. Which today are the network devices.
It has been suggested that a better fix would be to change the parent
device from a class device to a bus device, which in the case of the
bluetooth driver would change /sys/class/bluetooth to /sys/bus/bluetoth,
I can not see how we would avoid significant userspace breakage if we
were to make that change.
Adding an extra directory in the path to the device will also be
userspace visible but it is much less likely to break things.
Everything is still accessible from /sys/class (for example), and it
fixes two bugs. Adding an extra directory fixes a 3 year old regression
introduced with the new sysfs layout that makes it impossible to rename
bnep0 network devices to names that conflict with hci device attributes
like hci_revsion. Adding an additional directory removes the new
failure modes introduced by the network namespace code.
If it weren't for the regession in the renaming of network devices I
would figure out how to just make the sysfs code deal with this
configuration of devices.
In summary this patch fixes regressions by changing:
"/sys/class/bluetooth/hci0/bnep0" to "/sys/class/bluetooth/hci0/net/bnep0".

virtio ring was changed to return an error code on OOM,
but one caller was missed and still checks for vq->vring.num.
The fix is just to check for <0 error code.
Long term it might make sense to change goto add_head to
just return an error on oom instead, but let's apply
a minimal fix for 2.6.35.

The KEXEC_*_MEMORY_LIMITs are inclusive addresses. We define them as
2Gs as that is what we allow mapping via TLBs. However, this should be
2G - 1 to be inclusive, otherwise if we have >2G of memory in a system
we fail to boot properly via kexec.

The .data..init_task output section was missing
a load offset causing a popwerpc target to fail to boot.
Sean MacLennan tracked it down to the definition of
INIT_TASK_DATA_SECTION().
There are only two users of INIT_TASK_DATA_SECTION()
in the kernel today: cris and popwerpc.
cris do not support relocatable kernels and is thus not
impacted by this change.
Fix INIT_TASK_DATA_SECTION() to specify load offset like
all other output sections.

Oooops... we missed these. We incorrectly converted strings
used when parsing the device-tree on pseries, thus breaking
access to drconf memory and hotplug memory.
While at it, also revert some variable names that represent
something the FW calls "lmb" and thus don't need to be converted
to "memblock".

This adds some debug output to our MMU hash code to print out some
useful debug data if the hypervisor refuses the insertion (which
should normally never happen).

There's a couple of nasty bugs lurking in our huge page hashing code.
First, we don't check the access permission atomically with setting
the _PAGE_BUSY bit, which means that the PTE value we end up using
for the hashing might be different than the one we have checked
the access permissions for.
We've seen cases where that leads us to try to use an invalidated
PTE for hashing, causing all sort of "interesting" issues.
Then, we also failed to set _PAGE_DIRTY on a write access.
Finally, a minor tweak but we should return 0 when we find the
PTE busy, in order to just re-execute the access, rather than 1
which means going to do_page_fault().

| | | | | | | | | | |
| | | | | | | | | | | |
Instead of adding _PAGE_PRESENT to the access permission mask
in each low level routine independently, we add it once from
hash_page().
We also move the preliminary access check (the racy one before
the PTE is locked) up so it applies to the huge page case. This
duplicates code in __hash_page_huge() which we'll remove in a
subsequent patch to fix a race in there.

If the hypervisor gives us an error on a hugepage insert we panic. The
normal page code already handles this by returning an error instead and we end
calling low_hash_fault which will just kill the task if possible.
The patch below does a similar thing for the hugepage case.

nconfig segfaults when help text contains the character '%'. For a quick
example, navigate to the kernel compression options and get the help for
bzip2. Doing so triggers a call to mvwprintw() with a string containing
'%' and no extra arguments to fill in the specifier's value. Fix this
case by printing the literal string retrieved from the kconfig.

The 'source' builtin is a bash alias to the '.' (dot) builtin. While the
former is supported only by bash, the latter is specified in POSIX and
works fine with all POSIX-compliant shells I am aware of.
The '$_' special parameter is specific to bash. It is partially
supported in dash too but it always evaluates to the current script path
(which causes the script to enter a loop recursively re-executing
itself). This is why I have replaced the two occurences of '$_' with the
explicit parameter.
The 'local' builtin is another example of bash-specific code. Although
it is supported by all POSIX-compliant shells I am aware of, it is not
part of POSIX specification and thus the code should not rely on it
assigning a specific value to the local variable. Moreover, the 'posh'
shell has a limited version of 'local' builtin not supporting direct
variable assignments. Thus, I have broken one of the 'local'
declarations down into a (non-POSIX) 'local' declaration and a plain
(POSIX-compliant) variable assignment.

make version 3.80 doesn't support "else ifdef" on the same line, also it
doesn't support unindented nested constructs.
Build fails with:
Makefile:608: Extraneous text after `else' directive
Makefile:611: *** only one `else' per conditional. Stop.
This patch fixes the build for make 3.80.

When parsing the objdump disassembly output we can have goto labels that
are valid hex numbers and thus get confused with lines with machine
code.
Handle the common case of a label that has nothing after it and other
cases where there is just source code by validating the resulting "ip".
It is still possible that we find goto labels that are in the function
address range, but only if they are located before the real address we
should be OK.
A change in the objdump output to have a clear marker separating
addresses from the disassembly would come handy, but we would still have
to deal with older versions.

We define a number of symbols in the linker scipt like this:
__start_syscalls_metadata = .;
*(__syscalls_metadata)
But we do not know the alignment of "." when we assign
the __start_syscalls_metadata symbol.
gcc started to uses bigger alignment for structs (32 bytes),
so we saw situations where the linker due to alignment
constraints increased the value of "." after the symbol assignment.
This resulted in boot fails.
Fix this by forcing a 32 byte alignment of "." before the
assignment.
This patch introduces the forced alignment for
ftrace_events and syscalls_metadata.
It may be required in more places.

Error: perfcounter syscall returned with -1 (Too many open files)
Fatal: No CONFIG_PERF_EVENTS=y kernel support configured?
Looking into perf, I found perf opens too many directories at
initialization time, but forgets to close them. Here is the fix.

Hists that have been filtered, because they don't have callchains
matching the parent filter, won't be printed. As such,
hist_entry__snprintf() returns 0 for them, but we don't control
this value and we always print the buffer, which might be
untouched and then only made of random stack garbage.
Not only does it paint the screen with barf, it also prints
the callchains for these hists, even though they have been filtered,
since the hist has been filtered as well.
We need to check the return value of hist_entry__snprintf() and
ignore the hist if it is 0, which means it didn't get any callchain
matching the parent filter. This fixes the barf and the undesired
callchains.

The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c)
defines a key map for the matrix keypad keyboard. The hardware seems to
use all of the 8 rows and 8 columns of the keypad, although not all
possible locations are used.
The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys
are defined with a row and column number between 0 and 7, except
KEY(0xff, 2, KEY_F9),
KEY(0xff, 4, KEY_F10),
KEY(0xff, 5, KEY_F11),
which represent keycodes that should be emitted when entire row is
connected to the ground. since the driver handles this case as if we
had an extra column in the key matrix. Unfortunately we do not allocate
enough space and end up owerwriting some random memory.

We only add/remove crtcs at driver load, you cannot remove when
the GPU is running a CS packet since the fd is open, when
GPU hotplugging on radeons actually is needed all this locking
needs a review and I've started re-working kms core locking to deal
with this better. But for now avoid long delays in CS processing when
hotplug detect is happening in a different thread.
this fixes a regression introduced with hotplug detection.

In the CONFIG_AUDITSYSCALL fast-path for x86 64-bit system calls,
we can pass a bad return value and/or error indication for the
system call to audit_syscall_exit(). This happens when
TIF_NEED_RESCHED was set as the system call returned, so we went
out to schedule() and came back to the exit-audit fast-path. The
fix is to reload the user return value register from the pt_regs
before using it for audit_syscall_exit().
Both the 32-bit kernel's fast path and the 64-bit kernel's 32-bit
system call fast paths work slightly differently, so that they
always leave the fast path entirely to reschedule and don't return
there, so they don't have the analogous bugs.

The kdb code should not toggle the sysrq state in case an end user
wants to try and resume the normal kernel execution.
