2020-10-05regulator: Make constraint debug processing conditional on DEBUGGeert Uytterhoeven
If debugging is disabled, print_constraints() does not print the actual constraints, but still performs some processing and string formatting, only to throw away the result later. Fix this by moving all constraint debug processing to a separate function, and replacing it by a dummy when debugging is disabled. This reduces kernel size by almost 800 bytes (on arm/arm64).

2020-10-03mm/page_alloc: handle a missing case for memalloc_nocma_{save/restore} APIsJoonsoo Kim
memalloc_nocma_{save/restore} APIs can be used to skip page allocation on CMA area, but, there is a missing case and the page on CMA area could be allocated even if APIs are used. This patch handles this case to fix the potential issue. For now, these APIs are used to prevent long-term pinning on the CMA page. When the long-term pinning is requested on the CMA page, it is migrated to the non-CMA page before pinning. This non-CMA page is allocated by using memalloc_nocma_{save/restore} APIs. If APIs doesn't work as intended, the CMA page is allocated and it is pinned for a long time. This long-term pin for the CMA page causes cma_alloc() failure and it could result in wrong behaviour on the device driver who uses the cma_alloc(). Missing case is an allocation from the pcplist. MIGRATE_MOVABLE pcplist could have the pages on CMA area so we need to skip it if ALLOC_CMA isn't specified.

2020-10-03mm, slub: restore initial kmem_cache flagsEric Farman
The routine that applies debug flags to the kmem_cache slabs inadvertantly prevents non-debug flags from being applied to those same objects. That is, if slub_debug=<flag>,<slab> is specified, non-debugged slabs will end up having flags of zero, and the slabs may be unusable. Fix this by including the input flags for non-matching slabs with the contents of slub_debug, so that the caches are created as expected alongside any debugging options that may be requested. With this, we can remove the check for a NULL slub_debug_string, since it's covered by the loop itself.

2020-10-03KVM: VMX: update PFEC_MASK/PFEC_MATCH together with PF interceptPaolo Bonzini
The PFEC_MASK and PFEC_MATCH fields in the VMCS reverse the meaning of the #PF intercept bit in the exception bitmap when they do not match. This means that, if PFEC_MASK and/or PFEC_MATCH are set, the hypervisor can get a vmexit for #PF exceptions even when the corresponding bit is clear in the exception bitmap. This is unexpected and is promptly detected by a WARN_ON_ONCE. To fix it, reset PFEC_MASK and PFEC_MATCH when the #PF intercept is disabled (as is common with enable_ept && !allow_smaller_maxphyaddr).

2020-10-01pipe: remove pipe_wait() and fix wakeup race with spliceLinus Torvalds
The pipe splice code still used the old model of waiting for pipe IO by using a non-specific "pipe_wait()" that waited for any pipe event to happen, which depended on all pipe IO being entirely serialized by the pipe lock. So by checking the state you were waiting for, and then adding yourself to the wait queue before dropping the lock, you were guaranteed to see all the wakeups. Strictly speaking, the actual wakeups were not done under the lock, but the pipe_wait() model still worked, because since the waiter held the lock when checking whether it should sleep, it would always see the current state, and the wakeup was always done after updating the state. However, commit 0ddad21d3e99 ("pipe: use exclusive waits when reading or writing") split the single wait-queue into two, and in the process also made the "wait for event" code wait for _two_ wait queues, and that then showed a race with the wakers that were not serialized by the pipe lock. It's only splice that used that "pipe_wait()" model, so the problem wasn't obvious, but Josef Bacik reports: "I hit a hang with fstest btrfs/187, which does a btrfs send into /dev/null. This works by creating a pipe, the write side is given to the kernel to write into, and the read side is handed to a thread that splices into a file, in this case /dev/null. The box that was hung had the write side stuck here [pipe_write] and the read side stuck here [splice_from_pipe_next -> pipe_wait]. [ more details about pipe_wait() scenario ] The problem is we're doing the prepare_to_wait, which sets our state each time, however we can be woken up either with reads or writes. In the case above we race with the WRITER waking us up, and re-set our state to INTERRUPTIBLE, and thus never break out of schedule" Josef had a patch that avoided the issue in pipe_wait() by just making it set the state only once, but the deeper problem is that pipe_wait() depends on a level of synchonization by the pipe mutex that it really shouldn't. And the whole "wait for any pipe state change" model really isn't very good to begin with. So rather than trying to work around things in pipe_wait(), remove that legacy model of "wait for arbitrary pipe event" entirely, and actually create functions that wait for the pipe actually being readable or writable, and can do so without depending on the pipe lock serializing everything.

2020-10-01regulator: qcom_smd: Add PM660/PM660L regulator supportAngeloGioacchino Del Regno
The PM660 and PM660L are a very very common PMIC combo, found on boards using the SDM630, SDM636, SDM660 (and SDA variants) SoC. PM660 provides 6 SMPS and 19 LDOs (of which one is unaccesible), while PM660L provides 5 SMPS (of which S3 and S4 are combined), 10 LDOs and a Buck-or-Boost (BoB) regulator. The PM660L IC also provides other regulators that are very specialized (for example, for the display) and will be managed in the other appropriate drivers (for example, labibb).

2020-10-01regulator: qcom_spmi: Add PM660/PM660L regulatorsAngeloGioacchino Del Regno
The PM660 PMIC is very often paired with the PM660L option on SDM630/663/660 (and SDA variants) boards. The PM660 has 11 "660" LDOs (2 NMOS, 9 PMOS) and 7 HT LDOs (4 NMOS, 3 PMOS) and a quirk: the L4 regulator is unaccessible or does not exist on the PMIC. The PM660L has 8 "660" LDOs (1 NMOS, 7 PMOS) and 2 HT NMOS LDOs.

2020-10-01regulator: core: Enlarge max OF property name length to 64 charsAngeloGioacchino Del Regno
Some regulator drivers may be defining very long names: this is the case with the qcom_smd and qcom_spmi regulators, where we need to parse the regulator parents from DT. For clarity, this is an example: { "l13a", QCOM_SMD_RPM_LDOA, 13, &pm660_ht_lvpldo, "vdd_l8_l9_l10_l11_l12_l13_l14" }, pm660-regulators { ... vdd_l8_l9_l10_l11_l12_l13_l14-supply = <&vreg_s4a_2p04> ... }; Now, with a 32 characters limit, the function is trying to parse, exactly, "vdd_l8_l9_l10_l11_l12_l13_l14-s" (32 chars) instead of the right one, which is 37 chars long in this specific case. ... And this is not only the case with PM660/PM660L, but also with PMA8084, PM8916, PM8950 and others that are not implemented yet. The length of 64 chars was chosen based on the longest parsed property name that I could find, which is in PM8916, and would be 53 characters long. At that point, rounding that to 64 looked like being the best idea.

2020-10-01xen/events: don't use chip_data for legacy IRQsJuergen Gross
Since commit c330fb1ddc0a ("XEN uses irqdesc::irq_data_common::handler_data to store a per interrupt XEN data pointer which contains XEN specific information.") Xen is using the chip_data pointer for storing IRQ specific data. When running as a HVM domain this can result in problems for legacy IRQs, as those might use chip_data for their own purposes. Use a local array for this purpose in case of legacy IRQs, avoiding the double use.

2020-10-01iommu/amd: Fix the overwritten field in IVMD headerAdrian Huang
Commit 387caf0b759a ("iommu/amd: Treat per-device exclusion ranges as r/w unity-mapped regions") accidentally overwrites the 'flags' field in IVMD (struct ivmd_header) when the I/O virtualization memory definition is associated with the exclusion range entry. This leads to the corrupted IVMD table (incorrect checksum). The kdump kernel reports the invalid checksum: ACPI BIOS Warning (bug): Incorrect checksum in table [IVRS] - 0x5C, should be 0x60 (20200717/tbprint-177) AMD-Vi: [Firmware Bug]: IVRS invalid checksum Fix the above-mentioned issue by modifying the 'struct unity_map_entry' member instead of the IVMD header.

Commit a0e50aa3f4a8 ("KVM: arm64: Factor out stage 2 page table data from struct kvm") dropped the ISB after __load_guest_stage2(), only leaving the one that is required when the speculative AT workaround is in effect. As Andrew points it: "This alternative is 'backwards' to avoid a double ISB as there is one in __load_guest_stage2 when the workaround is active." Restore the missing ISB, conditionned on the AT workaround not being active.
