Fix regression introduced with d435d862 ("cpu hotplug: mce: fix cpu hotplug error handling"). A CPU which was not brought up during boot (using maxcpus and additional_cpus parameters) couldn't be onlined anymore. For such a CPU it seemed that MCE was not supported during CPU_UP_PREPARE-time which caused mce_cpu_callback to return NOTIFY_BAD to notifier_call_chain. To fix this we: - call mce_create_device for CPU_ONLINE event (instead of CPU_UP_PREPARE), - avoid mce_remove_device() for the CPU that is not correctly initialized by mce_create_device() failure, - make mce_cpu_callback always return NOTIFY_OK for CPU_ONLINE event. Because CPU_ONLINE callback return value is always ignored.

Lockdep reports a circular locking dependency in the hibernate code because - during system boot hibernate code (from an initcall) locks pm_mutex and then a sysfs buffer mutex via name_to_dev_t - during regular operation hibernate code locks pm_mutex under a sysfs buffer mutex because it's called from sysfs methods. The deadlock can never happen because during initcall invocation nothing can write to sysfs yet. This removes the lockdep report by marking the initcall locking as being in a different class.

由 Russ Anderson 提交于
In __do_IRQ(), the normal case is that IRQ_DISABLED is checked and if set the handler (handle_IRQ_event()) is not called. Earlier in __do_IRQ(), if IRQ_PER_CPU is set the code does not check IRQ_DISABLED and calls the handler even though IRQ_DISABLED is set. This behavior seems unintentional. One user encountering this behavior is the CPE handler (in arch/ia64/kernel/mca.c). When the CPE handler encounters too many CPEs (such as a solid single bit error), it sets up a polling timer and disables the CPE interrupt (to avoid excessive overhead logging the stream of single bit errors). disable_irq_nosync() is called which sets IRQ_DISABLED. The IRQ_PER_CPU flag was previously set (in ia64_mca_late_init()). The net result is the CPE handler gets called even though it is marked disabled. If the behavior of not checking IRQ_DISABLED when IRQ_PER_CPU is set is intentional, it would be worthy of a comment describing the intended behavior. disable_irq_nosync() does call chip->disable() to provide a chipset specifiec interface for disabling the interrupt, which avoids this issue when used.

由 Eric W. Biederman 提交于
This is my trivial patch to swat innumerable little bugs with a single blow. After some intensive review (my apologies for not having gotten to this sooner) what we have looks like a good base to build on with the current pid namespace code but it is not complete, and it is still much to simple to find issues where the kernel does the wrong thing outside of the initial pid namespace. Until the dust settles and we are certain we have the ABI and the implementation is as correct as humanly possible let's keep process ID namespaces behind CONFIG_EXPERIMENTAL. Allowing us the option of fixing any ABI or other bugs we find as long as they are minor. Allowing users of the kernel to avoid those bugs simply by ensuring their kernel does not have support for multiple pid namespaces.

由 Arjan van de Ven 提交于
sys_open / sys_read were used in the early 1.2 days to load firmware from disk inside drivers. Since 2.0 or so this was deprecated behavior, but several drivers still were using this. Since a few years we have a request_firmware() API that implements this in a nice, consistent way. Only some old ISA sound drivers (pre-ALSA) still straggled along for some time.... however with commit c2b1239a the last user is now gone. This is a good thing, since using sys_open / sys_read etc for firmware is a very buggy to dangerous thing to do; these operations put an fd in the process file descriptor table.... which then can be tampered with from other threads for example. For those who don't want the firmware loader, filp_open()/vfs_read are the better APIs to use, without this security issue. The patch below marks sys_open and sys_read unused now that they're really not used anymore, and for deletion in the 2.6.25 timeframe.

由 Christian Borntraeger 提交于
We have seen ramdisk based install systems, where some pages of mapped libraries and programs were suddendly zeroed under memory pressure. This should not happen, as the ramdisk avoids freeing its pages by keeping them dirty all the time. It turns out that there is a case, where the VM makes a ramdisk page clean, without telling the ramdisk driver. On memory pressure shrink_zone runs and it starts to run shrink_active_list. There is a check for buffer_heads_over_limit, and if true, pagevec_strip is called. pagevec_strip calls try_to_release_page. If the mapping has no releasepage callback, try_to_free_buffers is called. try_to_free_buffers has now a special logic for some file systems to make a dirty page clean, if all buffers are clean. Thats what happened in our test case. The simplest solution is to provide a noop-releasepage callback for the ramdisk driver. This avoids try_to_free_buffers for ramdisk pages.

Firmware like PNPBIOS or ACPI can report the address space consumed by the RTC. The actual space consumed may be less than the size (RTC_IO_EXTENT) assumed by the RTC driver. The PNP core doesn't request resources yet, but I'd like to make it do so. If/when it does, the RTC_IO_EXTENT request may fail, which prevents the RTC driver from loading. Since we only use the RTC index and data registers at RTC_PORT(0) and RTC_PORT(1), we can fall back to requesting just enough space for those. If the PNP core requests resources, this results in typical I/O port usage like this: 0070-0073 : 00:06 <-- PNP device 00:06 responds to 70-73 0070-0071 : rtc <-- RTC driver uses only 70-71 instead of the current: 0070-0077 : rtc <-- RTC_IO_EXTENT == 8 Signed-off-by: NBjorn Helgaas <bjorn.helgaas@hp.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
