2022-07-29Add SPI Driver to HPE GXP ArchitectureMark Brown
Merge series from nick.hawkins@hpe.com <nick.hawkins@hpe.com>: The GXP supports 3 separate SPI interfaces to accommodate the system flash, core flash, and other functions. The SPI engine supports variable clock frequency, selectable 3-byte or 4-byte addressing and a configurable x1, x2, and x4 command/address/data modes. The memory buffer for reading and writing ranges between 256 bytes and 8KB. This driver supports access to the core flash and bios part.

2022-07-29mm/hmm: fault non-owner device private entriesRalph Campbell
If hmm_range_fault() is called with the HMM_PFN_REQ_FAULT flag and a device private PTE is found, the hmm_range::dev_private_owner page is used to determine if the device private page should not be faulted in. However, if the device private page is not owned by the caller, hmm_range_fault() returns an error instead of calling migrate_to_ram() to fault in the page. For example, if a page is migrated to GPU private memory and a RDMA fault capable NIC tries to read the migrated page, without this patch it will get an error. With this patch, the page will be migrated back to system memory and the NIC will be able to read the data.

2022-07-29page_alloc: fix invalid watermark check on a negative valueJaewon Kim
There was a report that a task is waiting at the throttle_direct_reclaim. The pgscan_direct_throttle in vmstat was increasing. This is a bug where zone_watermark_fast returns true even when the free is very low. The commit f27ce0e14088 ("page_alloc: consider highatomic reserve in watermark fast") changed the watermark fast to consider highatomic reserve. But it did not handle a negative value case which can be happened when reserved_highatomic pageblock is bigger than the actual free. If watermark is considered as ok for the negative value, allocating contexts for order-0 will consume all free pages without direct reclaim, and finally free page may become depleted except highatomic free. Then allocating contexts may fall into throttle_direct_reclaim. This symptom may easily happen in a system where wmark min is low and other reclaimers like kswapd does not make free pages quickly. Handle the negative case by using MIN.

2022-07-29selftests/bpf: Bump internal send_signal/send_signal_tracepoint timeoutDaniel Müller
The send_signal/send_signal_tracepoint is pretty flaky, with at least one failure in every ten runs on a few attempts I've tried it: > test_send_signal_common:PASS:pipe_c2p 0 nsec > test_send_signal_common:PASS:pipe_p2c 0 nsec > test_send_signal_common:PASS:fork 0 nsec > test_send_signal_common:PASS:skel_open_and_load 0 nsec > test_send_signal_common:PASS:skel_attach 0 nsec > test_send_signal_common:PASS:pipe_read 0 nsec > test_send_signal_common:PASS:pipe_write 0 nsec > test_send_signal_common:PASS:reading pipe 0 nsec > test_send_signal_common:PASS:reading pipe error: size 0 0 nsec > test_send_signal_common:FAIL:incorrect result unexpected incorrect result: actual 48 != expected 50 > test_send_signal_common:PASS:pipe_write 0 nsec > #139/1 send_signal/send_signal_tracepoint:FAIL The reason does not appear to be a correctness issue in the strict sense. Rather, we merely do not receive the signal we are waiting for within the provided timeout. Let's bump the timeout by a factor of ten. With that change I have not been able to reproduce the failure in 150+ iterations. I am also sneaking in a small simplification to the test_progs test selection logic.

2022-07-29sparc: Use generic pci_mmap_resource_range()Arnd Bergmann
The main feature of the sparc-specific implementation of pci_mmap_resource_range() is that it allows mapping the entire PCI I/O space for a PCI host bridge using the /proc/bus/pci interface on a bridge device. The generic implementation cannot do this, but it also appears that this got broken for sparc by commit 9eff02e2042f ("PCI: check mmap range of /proc/bus/pci files too"), which enforces that each address is part of a BAR for kernels after 2.6.28. Remove it all, assuming that the corresponding user space code has already been changed to access /dev/ioport instead a long time ago. Add pci_iobar_pfn() to make it possible to map I/O resources. This is adapted from the powerpc version.

2022-07-29PCI: Remove pci_mmap_page_range() wrapperArnd Bergmann
The ARCH_GENERIC_PCI_MMAP_RESOURCE symbol came up in a recent discussion, and I noticed that this was left behind by an unfinished cleanup from 2017. The only architecture that still relies on providing its own pci_mmap_page_range() helper instead of using the generic pci_mmap_resource_range() is sparc. Presumably the reasons for this have not changed, but at least this can be simplified by converting sparc to use the same interface as the others. The only difference between the two is the device-specific offset that gets added to or subtracted from vma->vm_pgoff. Change the only caller of pci_mmap_page_range() in common code to subtract this offset and call the modern interface, while adding it back in the sparc implementation to preserve the existing behavior. This removes the complexities of the dual interfaces from the common code, and keeps it all specific to the sparc architecture code. According to David Miller, the sparc code lets user space poke into the VGA I/O port registers by mmapping the I/O space of the parent bridge device, which is something that the generic pci_mmap_resource_range() code apparently does not.
