2010-10-15ACPI / PM: Fix problems with acpi_pm_device_sleep_state()Rafael J. Wysocki
There is a number of problems with acpi_pm_device_sleep_state() now. First, if _S0W is not defined, it prevents devices from being put into D3 by PCI runtime PM, which shouldn't happen. Second, it shouldn't use adev->wakeup.state.enabled, because if it's set, it only means that either the device is permanently enabled to wake up the system, or that it has been enabled to do that through /proc/acpi/wakeup. Finally, it should be compiled if CONFIG_PM_SLEEP is not set, so that PCI runtime PM works correctly in that case. Fix these problems.

2010-10-15llseek: automatically add .llseek fopArnd Bergmann
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

2010-10-01ACPI: Do not export hid/modalias sysfs file for ACPI objects without a HIDThomas Renninger
Boot and compile tested. The fact that pnp.ids can now be empty needs testing on some further machines, though. This should handle a "modprobe is wrongly called by udev" issue: https://bugzilla.kernel.org/show_bug.cgi?id=19162 Modaliase files in /sys/devices/LNXSYSTM:00/ went down from 113 to 71 on my tested system. This is a sysfs change, but userspace must already be able to handle it. Also do not fill up pnp.ids list with a "struct hid" entry. This comment: * This generic ID isn't useful for driver binding, but it provides * the useful property that "every acpi_device has an ID." is still half way true: Best you never touch pnp.ids list directly or make sure it can be empty, instead use: char *acpi_device_hid() which always returns a value ("device" as a dummy if the object has no hid).

2010-09-29ACPI, APEI, HEST Fix the unsuitable usage of platform_dataJin Dongming
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() Signed-off-by: Jin Dongming <jin.dongming@np.css.fujitsu.com> Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-09-29ACPI, APEI, Fix acpi_pre_map() return valueJin Dongming
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 acpi_pre_map() using the ioremap() result "map->vaddr" instead. v2: Modified the unsuitable description of patch. v3: Removed unlikely() check and made description simpler.

2010-09-29ACPI, APEI, Fix APEI related table size checkingHuang Ying
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 Originally-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
