mm, page_alloc: extend kernelcore and movablecore for percent
Both kernelcore= and movablecore= can be used to define the amount of ZONE_NORMAL and ZONE_MOVABLE on a system, respectively. This requires the system memory capacity to be known when specifying the command line, however. This introduces the ability to define both kernelcore= and movablecore= as a percentage of total system memory. This is convenient for systems software that wants to define the amount of ZONE_MOVABLE, for example, as a proportion of a system's memory rather than a hardcoded byte value. To define the percentage, the final character of the parameter should be a '%'. mhocko: "why is anyone using these options nowadays?" rientjes: : : Fragmentation of non-__GFP_MOVABLE pages due to low on memory : situations can pollute most pageblocks on the system, as much as 1GB of : slab being fragmented over 128GB of memory, for example. When the : amount of kernel memory is well bounded for certain systems, it is : better to aggressively reclaim from existing MIGRATE_UNMOVABLE : pageblocks rather than eagerly fallback to others. : : We have additional patches that help with this fragmentation if you're : interested, specifically kcompactd compaction of MIGRATE_UNMOVABLE : pageblocks triggered by fallback of non-__GFP_MOVABLE allocations and : draining of pcp lists back to the zone free area to prevent stranding.

Merge tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pul removal of obsolete architecture ports from Arnd Bergmann:
"This removes the entire architecture code for blackfin, cris, frv,
m32r, metag, mn10300, score, and tile, including the associated device
drivers.
I have been working with the (former) maintainers for each one to
ensure that my interpretation was right and the code is definitely
unused in mainline kernels. Many had fond memories of working on the
respective ports to start with and getting them included in upstream,
but also saw no point in keeping the port alive without any users.
In the end, it seems that while the eight architectures are extremely
different, they all suffered the same fate: There was one company in
charge of an SoC line, a CPU microarchitecture and a software
ecosystem, which was more costly than licensing newer off-the-shelf
CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
seems that all the SoC product lines are still around, but have not
used the custom CPU architectures for several years at this point. In
contrast, CPU instruction sets that remain popular and have actively
maintained kernel ports tend to all be used across multiple licensees.
[ See the new nds32 port merged in the previous commit for the next
generation of "one company in charge of an SoC line, a CPU
microarchitecture and a software ecosystem" - Linus ]
The removal came out of a discussion that is now documented at
https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
marking any ports as deprecated but remove them all at once after I
made sure that they are all unused. Some architectures (notably tile,
mn10300, and blackfin) are still being shipped in products with old
kernels, but those products will never be updated to newer kernel
releases.
After this series, we still have a few architectures without mainline
gcc support:
- unicore32 and hexagon both have very outdated gcc releases, but the
maintainers promised to work on providing something newer. At least
in case of hexagon, this will only be llvm, not gcc.
- openrisc, risc-v and nds32 are still in the process of finishing
their support or getting it added to mainline gcc in the first
place. They all have patched gcc-7.3 ports that work to some
degree, but complete upstream support won't happen before gcc-8.1.
Csky posted their first kernel patch set last week, their situation
will be similar
[ Palmer Dabbelt points out that RISC-V support is in mainline gcc
since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]"

PCI/portdrv: Remove unnecessary "pcie_ports=auto" parameter
The "pcie_ports=auto" parameter set pcie_ports_disabled and pcie_ports_auto to their compiled-in defaults, so specifying the parameter is the same as not using it at all. Remove the "pcie_ports=auto" parameter and update the documentation. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

Documentation: arch-support: remove obsolete architectures
A number of architecture ports are obsolete and getting dropped, so we no longer want to track the respective features.

HID: usbhid: extend the polling interval configuration to keyboards
For mouse and joystick devices user can change the polling interval via usbhid.mousepoll and usbhid.jspoll. Implement the same thing for keyboards, so user can reduce(or increase) input latency this way. This has been tested with a Cooler Master Devastator with kbpoll=32, resulting in delay between events of 32 ms(values were taken from evtest).

ima: fail signature verification based on policy
This patch addresses the fuse privileged mounted filesystems in environments which are unwilling to accept the risk of trusting the signature verification and want to always fail safe, but are for example using a pre-built kernel. This patch defines a new builtin policy named "fail_securely", which can be specified on the boot command line as an argument to "ima_policy=".

usb: core: Add "quirks" parameter for usbcore
Trying quirks in usbcore needs to rebuild the driver or the entire kernel if it's builtin. It can save a lot of time if usbcore has similar ability like "usbhid.quirks=" and "usb-storage.quirks=". Rename the original quirk detection function to "static" as we introduce this new "dynamic" function. Now users can use "usbcore.quirks=" as short term workaround before the next kernel release. Also, the quirk parameter can XOR the builtin quirks for debugging purpose. This is inspired by usbhid and usb-storage.

KVM: x86: Add module parameter for supporting VMware backdoor
Support access to VMware backdoor requires KVM to intercept #GP exceptions from guest which introduce slight performance hit. Therefore, control this support by module parameter. Note that module parameter is exported as it should be consumed by kvm_intel & kvm_amd to determine if they should intercept #GP or not. This commit doesn't change semantics. It is done as a preparation for future commits.

arch: remove blackfin port
The Analog Devices Blackfin port was added in 2007 and was rather active for a while, but all work on it has come to a standstill over time, as Analog have changed their product line-up. Aaron Wu confirmed that the architecture port is no longer relevant, and multiple people suggested removing blackfin independently because of some of its oddities like a non-working SMP port, and the amount of duplication between the chip variants, which cause extra work when doing cross-architecture changes.

irqchip/gic-v3: Allow LPIs to be disabled from the command line
For most GICv3 implementations, enabling LPIs is a one way switch. Once they're on, there is no turning back, which completely kills kexec (pending tables will always be live, and we can't tell the secondary kernel where they are). This is really annoying if you plan to use Linux as a bootloader, as it pretty much guarantees that the secondary kernel won't be able to use MSIs, and may even see some memory corruption. Bad. A workaround for this unfortunate situation is to allow the kernel not to enable LPIs, even if the feature is present in the HW. This would allow Linux-as-a-bootloader to leave LPIs alone, and let the secondary kernel to do whatever it wants with them. Let's introduce a boolean "irqchip.gicv3_nolpi" command line option that serves that purpose. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> |
