2019-08-08PCI: Correct pci=resource_alignment parameter exampleAlexey Kardashevskiy1-2/+3
The "pci=resource_alignment" parameter is described as requiring an order (not a size) and the code in pci_specified_resource_alignment() expects an order. But the example wrongly shows a size. Convert the example to an order.

2019-07-31docs: fs: cifs: convert to ReST and add to admin-guide bookMauro Carvalho Chehab8-0/+1209
The filenames for cifs documentation is not using the same convention as almost all Kernel documents is using. So, rename them to a more appropriate name. Then, manually convert the documentation files for CIFS to ReST. By doing a manual conversion, we can preserve the original author's style, while making it to look more like the other Kernel documents. Most of the conversion here is trivial. The most complex one was the README file (which was renamed to usage.rst). Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2019-07-17x86: Add "nopv" parameter to disable PV extensionsZhenzhong Duan1-0/+5
In virtualization environment, PV extensions (drivers, interrupts, timers, etc) are enabled in the majority of use cases which is the best option. However, in some cases (kexec not fully working, benchmarking) we want to disable PV extensions. We have "xen_nopv" for that purpose but only for XEN. For a consistent admin experience a common command line parameter "nopv" set across all PV guest implementations is a better choice. There are guest types which just won't work without PV extensions, like Xen PV, Xen PVH and jailhouse. add a "ignore_nopv" member to struct hypervisor_x86 set to true for those guest types and call the detect functions only if nopv is false or ignore_nopv is true.

2019-07-16vmcore: add a kernel parameter novmcoreddKairui Song1-0/+11
Since commit 2724273e8fd0 ("vmcore: add API to collect hardware dump in second kernel"), drivers are allowed to add device related dump data to vmcore as they want by using the device dump API. This has a potential issue, the data is stored in memory, drivers may append too much data and use too much memory. The vmcore is typically used in a kdump kernel which runs in a pre-reserved small chunk of memory. So as a result it will make kdump unusable at all due to OOM issues. So introduce new 'novmcoredd' command line option. User can disable device dump to reduce memory usage. This is helpful if device dump is using too much memory, disabling device dump could make sure a regular vmcore without device dump data is still available.
