commit 54d77198 ("gpio: bail out silently on NULL descriptors") doesn't work for gpiod_to_irq(): drivers assume that NULL descriptors will give negative IRQ numbers in return. It has been pointed out that returning 0 is NO_IRQ and that drivers should be amended to treat this as an error, but that is for the longer term: now let us repair the semantics.

When histograms are not configured in the kernel, the ftracetest histogram selftests should return "unsupported" and not "Failed". To detect this, the test scripts have: FEATURE=`grep hist events/sched/sched_process_fork/trigger` if [ -z "$FEATURE" ]; then echo "hist trigger is not supported" exit_unsupported fi The problem is that '-e' is in effect and any error will cause the program to terminate. The grep for 'hist' fails, because it is not compiled it (thus unsupported), but because grep has an error code for failing to find the string, it causes the program to terminate, and is marked as a failed test. Namhyung Kim recommended to test for the "hist" file located in events/sched/sched_process_fork/hist instead, as it is more inline with the other checks. As the hist file is only created if the histogram feature is enabled, that is a valid check.

If a task uses a non constant string for the format parameter in trace_printk(), then the trace_printk_fmt variable is set to NULL. This variable is then saved in the __trace_printk_fmt section. The function hold_module_trace_bprintk_format() checks to see if duplicate formats are used by modules, and reuses them if so (saves them to the list if it is new). But this function calls lookup_format() that does a strcmp() to the value (which is now NULL) and can cause a kernel oops. This wasn't an issue till 3debb0a9 ("tracing: Fix trace_printk() to print when not using bprintk()") which added "__used" to the trace_printk_fmt variable, and before that, the kernel simply optimized it out (no NULL value was saved). The fix is simply to handle the NULL pointer in lookup_format() and have the caller ignore the value if it was NULL.

This patch fixes a non-booting issue in Mainline. When booting with a compressed kernel, we need to be careful how we populate memory close to DDR start. AUTO_ZRELADDR is enabled by default in multi-arch enabled configurations, which place some restrictions on where the kernel is placed and where it will be uncompressed to on boot. AUTO_ZRELADDR takes the decompressor code's start address and masks out the bottom 28 bits to obtain an address to uncompress the kernel to (thus a load address of 0x42000000 means that the kernel will be uncompressed to 0x40000000 i.e. DDR START on this platform). Even changing the load address to after the co-processor's shared memory won't render a booting platform, since the AUTO_ZRELADDR algorithm still ensures the kernel is uncompressed into memory shared with the first co-processor (0x40000000). Another option would be to move loading to 0x4A000000, since this will mean the decompressor will decompress the kernel to 0x48000000. However, this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of memory would essentially be wasted for no good reason. Until we can work with ST to find a suitable memory location to relocate co-processor shared memory, let's disable the shared memory nodes. This will ensure a working platform in the mean time. NB: The more observant of you will notice that we're leaving the DMU shared memory node enabled; this is because a) it is the only one in active use at the time of this writing and b) it is not affected by the current default behaviour which is causing issues.

Some Dell machines have especially broken SMM or BIOS which cause that once fan_type() is called then CPU fan speed going randomly up and down. And for fixing this behaviour reboot is required. So this patch creates fan_type blacklist of affected Dell machines and disallow fan_type() call on them to prevent that erratic behaviour. Old blacklist which disabled loading driver on some machines added in commits a4b45b25 ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100") and 6220f4eb ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8000") were moved to FAN_TYPE blacklist.

For security reasons ordinary user must not be able to control fan speed via /proc/i8k by default. Some malicious software running under "nobody" user could be able to turn fan off and cause HW problems. So this patch changes default value of "restricted" parameter to 1. Also restrict reading of DMI_PRODUCT_SERIAL from /proc/i8k via "restricted" parameter. It is because non root user cannot read DMI_PRODUCT_SERIAL from sysfs file /sys/class/dmi/id/product_serial. Old non secure behaviour of file /proc/i8k can be achieved by loading this module with "restricted" parameter set to 0. Note that this patch has effects only for kernels compiled with CONFIG_I8K and only for file /proc/i8k. Hwmon interface provided by this driver was not changed and root access for setting fan speed was needed also before.

With the introduction of the ISA_BUS_API Kconfig option, ISA-style drivers may be built for X86_64 architectures. This patch changes the ISA Kconfig option dependency of the WinSystems EBC-C384 watchdog timer driver to ISA_BUS_API, thus allowing it to build for X86_64 as it is expected to.

Several modern devices, such as PC/104 cards, are expected to run on modern systems via an ISA bus interface. Since ISA is a legacy interface for most modern architectures, ISA support should remain disabled in general. Support for ISA-style drivers should be enabled on a per driver basis. To allow ISA-style drivers on modern systems, this patch introduces the ISA_BUS_API and ISA_BUS Kconfig options. The ISA bus driver will now build conditionally on the ISA_BUS_API Kconfig option, which defaults to the legacy ISA Kconfig option. The ISA_BUS Kconfig option allows the ISA_BUS_API Kconfig option to be selected on architectures which do not enable ISA (e.g. X86_64). The ISA_BUS Kconfig option is currently only implemented for X86 architectures. Other architectures may have their own ISA_BUS Kconfig options added as required.

It's annoying to constantly see the same "Not yet implemented" message over and over with nothing able to be done about it, so rate limit it for now to keep user's logs "clean".

This reverts commit b5e12ec3 ("Staging: rtl8188eu: rtw_efuse: Use sizeof type *pointer instead of sizeof type."). This commit is wrong, the rtw_malloc2d helper function takes the size of the array elements as its 3th argument, whereas sizeof(*eFuseWord) gives the size of a pointer instead of the size of a u16. Since sizeof(void *) > sizeof(u16) this has no adverse effects, but it is still wrong.
