In amdgpu_ras_query_error_count() return an error if the device doesn't support RAS. This prevents that function from having to always set the values of the integer pointers (if set), and thus prevents function side effects--always to have to set values of integers if integer pointers set, regardless of whether RAS is supported or not--with this change this side effect is mitigated. Also, if no pointers are set, don't count, since we've no way of reporting the counts. Also, give this function a kernel-doc.

2021-07-11mm/rmap: fix old bug: munlocking THP missed other mlocksHugh Dickins1-5/+8
The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication. (I said the kernel recovers: but would page reclaim be likely to split THP before rediscovering that it's VM_LOCKED? I've not followed that up) Fixes: 9a73f61bdb8a ("thp, mlock: do not mlock PTE-mapped file huge pages") Signed-off-by: Hugh Dickins <hughd@google.com> Reviewed-by: Shakeel Butt <shakeelb@google.com> Acked-by: Kirill A.

commit 03623b4b041c ("rtc: pcf2127: add tamper detection support") added support for timestamp interrupts. However they are not being handled in the irq handler. If a timestamp interrupt occurs it results in kernel disabling the interrupt and displaying the call trace: [ 121.145580] irq 78: nobody cared (try booting with the "irqpoll" option) ...

Save time stamp before clearing TSF1 and TSF2 flags so that it can't be overwritten. Set a flag to mark if the timestamp is valid and only report to sysfs if the flag is set. To mimic the hardware behavior, don’t save another timestamp until the first one has been read by the userspace. However, if the alarm irq is not configured, keep the old way of handling timestamp interrupt in the timestamp0 sysfs calls.

2021-07-09SMB3.1.1: Add support for negotiating signing algorithmSteve French4-11/+86
Support for faster packet signing (using GMAC instead of CMAC) can now be negotiated to some newer servers, including Windows. See MS-SMB2 section 2.2.3.17. This patch adds support for sending the new negotiate context with the first of three supported signing algorithms (AES-CMAC) and decoding the response. A followon patch will add support for sending the other two (including AES-GMAC, which is fastest) and changing the signing algorithm used based on what was negotiated. To allow the client to request GMAC signing set module parameter "enable_negotiate_signing" to 1.

2021-07-09perf tools: Fix pattern matching for same substring in different PMU typeJin Yao3-2/+37
Some different PMU types may have the same substring. For example, on Icelake server we have PMU types "uncore_imc" and "uncore_imc_free_running". Both PMU types have the substring "uncore_imc". But the parser wrongly thinks they are the same PMU type. We enable an imc event, perf stat -e uncore_imc/event=0xe3/ -a -- sleep 1 Perf actually expands the event to: uncore_imc_0/event=0xe3/ uncore_imc_1/event=0xe3/ uncore_imc_2/event=0xe3/ uncore_imc_3/event=0xe3/ uncore_imc_4/event=0xe3/ uncore_imc_5/event=0xe3/ uncore_imc_6/event=0xe3/ uncore_imc_7/event=0xe3/ uncore_imc_free_running_0/event=0xe3/ uncore_imc_free_running_1/event=0xe3/ uncore_imc_free_running_3/event=0xe3/ uncore_imc_free_running_4/event=0xe3/ That's because the "uncore_imc_free_running" matches the pattern "uncore_imc*". Now we check that the last characters of PMU name is '_<digit>'. For example, for pattern "uncore_imc*", "uncore_imc_0" is parsed ok, but "uncore_imc_free_running_0" fails.
