2020-11-23arm64: expose FAR_EL1 tag bits in siginfoPeter Collingbourne1-6/+19
The kernel currently clears the tag bits (i.e. bits 56-63) in the fault address exposed via siginfo.si_addr and sigcontext.fault_address. However, the tag bits may be needed by tools in order to accurately diagnose memory errors, such as HWASan [1] or future tools based on the Memory Tagging Extension (MTE). Expose these bits via the arch_untagged_si_addr mechanism, so that they are only exposed to signal handlers with the SA_EXPOSE_TAGBITS flag set.

2020-11-09arm64: mm: tidy up top of kernel VA spaceArd Biesheuvel1-12/+10
Tidy up the way the top of the kernel VA space is organized, by mirroring the 256 MB region we have below the vmalloc space, and populating it top down with the PCI I/O space, some guard regions, and the fixmap region. The latter region is itself populated top down, and today only covers about 4 MB, and so 224 MB is ample, and no guard region is therefore required. The resulting layout is identical between 48-bit/4k and 52-bit/64k configurations.

2020-11-09arm64: mm: make vmemmap region a projection of the linear regionArd Biesheuvel1-15/+15
Now that we have reverted the introduction of the vmemmap struct page pointer and the separate physvirt_offset, we can simplify things further, and place the vmemmap region in the VA space in such a way that virtual to page translations and vice versa can be implemented using a single arithmetic shift. One happy coincidence resulting from this is that the 48-bit/4k and 52-bit/64k configurations (which are assumed to be the two most prevalent) end up with the same placement of the vmemmap region. In a subsequent patch, we will take advantage of this, and unify the memory maps even more.

2020-11-09arm64: mm: extend linear region for 52-bit VA configurationsArd Biesheuvel2-12/+10
For historical reasons, the arm64 kernel VA space is configured as two equally sized halves, i.e., on a 48-bit VA build, the VA space is split into a 47-bit vmalloc region and a 47-bit linear region. When support for 52-bit virtual addressing was added, this equal split was kept, resulting in a substantial waste of virtual address space in the linear region: 48-bit VA 52-bit VA 0xffff_ffff_ffff_ffff +-------------+ +-------------+ | vmalloc | | vmalloc | 0xffff_8000_0000_0000 +-------------+ _PAGE_END(48) +-------------+ | linear | : : 0xffff_0000_0000_0000 +-------------+ : : : : : : : : : : : : : : : : : currently : : unusable : : : : : : unused : : by : : : : : : : : hardware : : : : : : : 0xfff8_0000_0000_0000 : : _PAGE_END(52) +-------------+ : : | | : : | | : : | | : : | | : : | | : unusable : | | : : | linear | : by : | | : : | region | : hardware : | | : : | | : : | | : : | | : : | | : : | | : : | | 0xfff0_0000_0000_0000 +-------------+ PAGE_OFFSET +-------------+ As illustrated above, the 52-bit VA kernel uses 47 bits for the vmalloc space (as before), to ensure that a single 64k granule kernel image can support any 64k granule capable system, regardless of whether it supports the 52-bit virtual addressing extension. However, due to the fact that the VA space is still split in equal halves, the linear region is only 2^51 bytes in size, wasting almost half of the 52-bit VA space. Let's fix this, by abandoning the equal split, and simply assigning all VA space outside of the vmalloc region to the linear region. The KASAN shadow region is reconfigured so that it ends at the start of the vmalloc region, and grows downwards. That way, the arrangement of the vmalloc space (which contains kernel mappings, modules, BPF region, the vmemmap array etc) is identical between non-KASAN and KASAN builds, which aids debugging.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull char/misc fixes/removals from Greg KH: "Here's some small fixes for 5.10-rc2 and a big driver removal. The fixes are for some reported issues in the interconnect and coresight drivers, nothing major. The "big" driver removal is the MIC drivers have been asked to be removed as the hardware never shipped and Intel no longer wants to maintain something that no one can use. This is welcomed by many as the DMA usage of these drivers was "interesting" and the security people were starting to question some issues that were starting to be found in the codebase. Note, one of the subsystems for this driver, the "VOP" code, will probably come back in future kernel versions as it was looking to potentially solve some PCIe virtualization issues that a number of other vendors were wanting to solve. But as-is, this codebase didn't work for anyone else so no actual functionality is being removed.

The new DMA architecture introduced with AM64 introduced new event types: unampped events. These events are mapped within INTA in contrast to other K3 devices where the events with similar function was originating from the UDMAP or ringacc. The ti,unmapped-event-sources should contain phandle array to the devices in the system (typically DMA controllers) from where the unmapped events originate.

2020-10-30docs: ABI: sysfs-class-backlight: unify ABI documentationMauro Carvalho Chehab3-46/+65
Both adp8860 and adp8870 define some extensions to the backlight class. This causes warnings: Warning: /sys/class/backlight/<backlight>/ambient_light_level is defined 2 times: /sys/class/backlight/<backlight>/ambient_light_level:8 /sys/class/backlight/<backlight>/ambient_light_level:30 Warning: /sys/class/backlight/<backlight>/ambient_light_zone is defined 2 times: /sys/class/backlight/<backlight>/ambient_light_zone:18 /sys/class/backlight/<backlight>/ambient_light_zone:40 As ABI definitions shouldn't be duplicated. Unfortunately, the ABI is dependent on the specific device features. As such, ambient_light_level range is somewhat different among the supported devices. The ambient_light_zone is even worse: the meanings of each preset are different, and there's no ABI to retrieve the supported types nor their meanins. Unfortunately, it is too late to fix it without causing regressions, as this has been used since Kernel v2.6.35. Rewrite those ABI documentation using the current documentation as a reference, and double-checking at the datasheets: https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8870.pdf https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8860.pdf in order to properly document the differences between those two drivers.

2020-10-30docs: Kconfig/Makefile: add a check for broken ABI filesMauro Carvalho Chehab2-0/+15
The files under Documentation/ABI should follow the syntax as defined at Documentation/ABI/README. Allow checking if they're following the syntax by running the ABI parser script on COMPILE_TEST. With that, when there's a problem with a file under Documentation/ABI, it would produce a warning like: Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#14: What '/sys/bus/pci/devices/<dev>/aer_stats/aer_rootport_total_err_cor' doesn't have a description Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#21: What '/sys/bus/pci/devices/<dev>/aer_stats/aer_rootport_total_err_fatal' doesn't have a description Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/57a38de85cb4b548857207cf1fc1bf1ee08613c9.1604042072.git.mchehab+huawei@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
