kernel/ksysfs.c seems to be a random dumping group for misc globals that the rest of the tree depend on. This has caused problems with exports in the past when sysfs is disabled, which can already be observed in commit-id 51107301. The latest one is the kernel_kobj usage, which presently results in: fs/built-in.o: In function `debugfs_init': inode.c:(.init.text+0xc34): undefined reference to `kernel_kobj' make: *** [.tmp_vmlinux1] Error 1 kernel/ksysfs.c itself at this point only contains globals and some basic sysfs initialization, the sysfs initialization code is optimized out when we build with sysfs disabled. Given that, it's easier to just build in unconditionally, rather than trying to find some other random place to dump and initialize the globals. Additionally, the current trend seems to be decoupling of kobjects from sysfs, in which case it still makes sense to perform the kernel_kobj initialization that happens here even if sysfs is disabled, as lib/kobject.o is built-in unconditionally.

In power_supply_create_attrs(), we create static attributes as referenced by power_supply_static_attrs[i]. After that, if we fail, we unregister via power_supply_static_attrs[psy->properties[i]]. This is incorrect, as psy->properties has absolutely no bearing on static attribs. This patch fixes it to unregister the correct attrib. Another line which was unnecessarily line wrapped is also unwrapped. Signed-off-by:

The CAPACITY_LEVEL stuff defines various levels of charge; however, what is the difference between them? What differentiates between HIGH and NORMAL, LOW and CRITICAL, etc? As it appears that these are fairly arbitrary, we end up making such policy decisions in the kernel (or in hardware). This is the sort of decision that should be made in userspace, not in the kernel. If the hardware does not support _CAPACITY and it cannot be easily calculated, then perhaps the driver should register a custom CAPACITY_LEVEL attribute; however, userspace should not become accustomed to looking for such a thing, and we should certainly not encourage drivers to provide CAPACITY_LEVEL stubs. The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL. The OLPC battery driver is the only driver making use of this, so it's removed from there as well. Signed-off-by:

swsusp_pg_dir[] is used for suspend, but not for hibernation. clean-up the ifdefs which worked by accident, while implying the opposite. Delete the __nosavedata, which also implied the opposite. Some day we may optimize CONFIG_ACPI_SLEEP to build minimal kernels for just hibernate or just suspend but not both, but today isn't that day. Signed-off-by:

Following the recent change in the suspend code path, switch consoles before calling PM notifiers during hibernation. Signed-off-by:
-
Johannes Berg authored
In order to fix APM emulation it is necessary to enable apm-emulation notifications for suspends triggered in various ways via the suspend notifiers. However, this will cause the systems using APM emulation to lock up between X being needed to switch away from the VT and X already waiting for resume in the APM ioctl. This patch moves the console switch (if enabled) before the suspend notification (and after the resume notification) to avoid this issue. Signed-off-by:

The ACPI 1.0 specification wants us to put devices into low power states after executing the _PTS global control method, while ACPI 2.0 and later want us to do that in the reverse order. The current hibernation code follows ACPI 2.0 in that respect which may cause some ACPI 1.0x systems to hang during hibernation (ref. http://bugzilla.kernel.org/show_bug.cgi?id=9528). Make the hibernation code execute _PTS before putting devices into low power states (ie. in accordance with ACPI 1.0x) with the possibility to override that using the 'acpi_new_pts_ordering' kernel command line option.

The preparation to enter an ACPI system sleep state is now tied to the disabling of GPEs, but the GPEs should not be disabled before suspending devices. Since on ACPI 1.0x systems the _PTS global control method should be executed before suspending devices, we need to disable GPEs separately. Signed-off-by:

The execution of ACPI global control methods _GTS and _BFS is currently tied to the preparation to enter a sleep state and to the leaving of the sleep state, respectively. However, these functions are called before disabling the nonboot CPUs and after enabling them, respectively (in fact, on ACPI 1.0x systems the first of them ought to be called before suspending devices), while according to the ACPI specification, _GTS is to be executed right prior to entering the system sleep state and _BFS is to be executed right after the platfor firmware has returned control to the OS on wake up. Move the execution of _GTS and _BFS to the right places. Signed-off-by:

On ACPI systems the target state set by acpi_pm_set_target() is reset by acpi_pm_finish(), but that need not be called if the suspend fails. All platforms that use the .set_target() global suspend callback are affected by analogous issues. For this reason, we need an additional global suspend callback that will reset the target state regardless of whether or not the suspend is successful. Also, it is reasonable to rename the .set_target() callback, since it will be used for a different purpose on ACPI systems (due to ACPI 1.0x code ordering requirements). Introduce the global suspend callback .end() to be executed at the end of the suspend sequence and rename the .set_target() global suspend callback to .begin(). Signed-off-by:
