2021-11-01iio: adc: aspeed: Support battery sensing.Billy Tsai1-3/+78
In ast2600, ADC integrate dividing circuit at last input channel for battery sensing. This patch use the dts property "battery-sensing" to enable this feature makes the last channel of each adc can tolerance higher voltage than reference voltage. The offset interface of ch7 will be separated when enabling the battery sensing mode.

2021-11-01iio: adc: aspeed: Fix the calculate error of clock.Billy Tsai1-0/+27
The ADC clock formula is ast2400/2500: ADC clock period = PCLK * 2 * (ADC0C[31:17] + 1) * (ADC0C[9:0] + 1) ast2600: ADC clock period = PCLK * 2 * (ADC0C[15:0] + 1) They all have one fixed divided 2 and the legacy driver didn't handle it. This patch register the fixed factory clock device as the parent of ADC clock scaler to fix this issue.

This patch refactors the model data structure to distinguish the function form different versions of aspeed ADC. - Rename the vref_voltage to vref_fixed_mv and add vref_mv driver data When driver probe will check vref_fixed_mv value and store it to vref_mv which isn't const value. - Add num_channels Make num_channles of iio device can be changed by different model_data - Add need_prescaler flag and scaler_bit_width The need_prescaler flag is used to tell the driver the clock divider needs another Prescaler and the scaler_bit_width to set the clock divider bitfield width.

2021-10-31perf script: Fix PERF_SAMPLE_WEIGHT_STRUCT supportKan Liang1-1/+1
-F weight in perf script is broken. # ./perf mem record # ./perf script -F weight Samples for 'dummy:HG' event do not have WEIGHT attribute set. Cannot print 'weight' field. The sample type, PERF_SAMPLE_WEIGHT_STRUCT, is an alternative of the PERF_SAMPLE_WEIGHT sample type. They share the same space, weight. The lower 32 bits are exactly the same for both sample type. The higher 32 bits may be different for different architecture. For a new kernel on x86, the PERF_SAMPLE_WEIGHT_STRUCT is used. For an old kernel or other ARCHs, the PERF_SAMPLE_WEIGHT is used. With -F weight, current perf script will only check the input string "weight" with the PERF_SAMPLE_WEIGHT sample type. Because the commit ea8d0ed6eae3 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") didn't update the PERF_SAMPLE_WEIGHT_STRUCT sample type for perf script. For a new kernel on x86, the check fails. Use PERF_SAMPLE_WEIGHT_TYPE, which supports both sample types, to replace PERF_SAMPLE_WEIGHT Fixes: ea8d0ed6eae37b01 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") Reported-by: Joe Mario <jmario@redhat.com> Reviewed-by: Kajol Jain <kjain@linux.ibm.com> Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Tested-by: Jiri Olsa <jolsa@redhat.com> Tested-by: Joe Mario <jmario@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Acked-by: Joe Mario <jmario@redhat.com> Cc: Andi Kleen <ak@linux.intel.com> Link: https://lore.kernel.org/r/1632929894-102778-1-git-send-email-kan.liang@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2021-10-31perf script: Check session->header.env.arch before using itSong Liu1-4/+8
When perf.data is not written cleanly, we would like to process existing data as much as possible (please see f_header.data.size == 0 condition in perf_session__read_header). However, perf.data with partial data may crash perf. Specifically, we see crash in 'perf script' for NULL session->header.env.arch. Fix this by checking session->header.env.arch before using it to determine native_arch. Also split the if condition so it is easier to read. Committer notes: If it is a pipe, we already assume is a native arch, so no need to check session->header.env.arch.

2021-10-30scsi: ufs: ufshpb: Remove HPB2.0 flowsAvri Altman3-288/+4
The Host Performance Buffer feature allows UFS read commands to carry the physical media addresses along with the LBAs, thus allowing less internal L2P-table switches in the device. HPB1.0 allowed a single LBA, while HPB2.0 increases this capacity up to 255 blocks. Carrying more than a single record, the read operation is no longer purely of type "read" but a "hybrid" command: Writing the physical address to the device in one operation and reading back the required payload in another. The JEDEC HPB spec defines two commands for this operation: HPB-WRITE-BUFFER (0x2) to write the physical addresses to device, and HPB-READ to read the payload. With the current HPB design the UFS driver has no alternative but to divide the READ request into 2 separate commands: HPB-WRITE-BUFFER and HPB-READ. This causes a great deal of aggravation to the block layer guys who demanded that we completely revert the entire HPB driver regardless of the huge amount of corporate effort already invested in it. As a compromise, remove only the pieces that implement the 2.0 specification. This is done as a matter of urgency for the final 5.15 release.

2021-10-29scsi: mpt3sas: Fix reference tag handling for WRITE_INSERTMartin K. Petersen1-3/+6
Testing revealed a problem with how the reference tag was handled for a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when the controller is asked to generate the protection information (i.e. not DIX). And as a result the initial reference tag would not be set in the WRITE_INSERT case. Separate handling of the REF_CHECK and REF_INCREMENT flags to align with both the DIX spec and the MPI implementation.

git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux Pull btrfs fixes from David Sterba: "Last minute fixes for crash on 32bit architectures when compression is in use. It's a regression introduced in 5.15-rc and I'd really like not let this into the final release, fixes via stable trees would add unnecessary delay. The problem is on 32bit architectures with highmem enabled, the pages for compression may need to be kmapped, while the patches removed that as we don't use GFP_HIGHMEM allocations anymore. The pages that don't come from local allocation still may be from highmem. Despite being on 32bit there's enough such ARM machines in use so it's not a marginal issue. I did full reverts of the patches one by one instead of a huge one. There's one exception for the "lzo" revert as there was an intermediate patch touching the same code to make it compatible with subpage. I can't revert that one too, so the revert in lzo.c is manual. Qu Wenruo has worked on that with me and verified the changes" * tag 'for-5.15-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: Revert "btrfs: compression: drop kmap/kunmap from lzo" Revert "btrfs: compression: drop kmap/kunmap from zlib" Revert "btrfs: compression: drop kmap/kunmap from zstd" Revert "btrfs: compression: drop kmap/kunmap from generic helpers"

2021-10-29riscv: Do not re-populate shadow memory with kasan_populate_early_shadowAlexandre Ghiti1-11/+0
When calling this function, all the shadow memory is already populated with kasan_early_shadow_pte which has PAGE_KERNEL protection. kasan_populate_early_shadow write-protects the mapping of the range of addresses passed in argument in zero_pte_populate, which actually write-protects all the shadow memory mapping since kasan_early_shadow_pte is used for all the shadow memory at this point. And then when using memblock API to populate the shadow memory, the first write access to the kernel stack triggers a trap. This becomes visible with the next commit that contains a fix for asan-stack. We already manually populate all the shadow memory in kasan_early_init and we write-protect kasan_early_shadow_pte at the end of kasan_init which makes the calls to kasan_populate_early_shadow superfluous so we can remove them.

2021-10-29Revert "btrfs: compression: drop kmap/kunmap from lzo"David Sterba1-11/+25
This reverts commit 8c945d32e60427cbc0859cf7045bbe6196bb03d8. The kmaps in compression code are still needed and cause crashes on 32bit machines (ARM, x86). Reproducible eg. by running fstest btrfs/004 with enabled LZO or ZSTD compression. The revert does not apply cleanly due to changes in a6e66e6f8c1b ("btrfs: rework lzo_decompress_bio() to make it subpage compatible") that reworked the page iteration so the revert is done to be equivalent to the original code.

Kunit test cases for 'damon_split_regions_of()' expects the number of regions after calling the function will be same to their request ('nr_sub'). However, the requested number is just an upper-limit, because the function randomly decides the size of each sub-region. This fixes the wrong expectation.

2021-10-29mm: khugepaged: skip huge page collapse for special filesYang Shi1-8/+11
The read-only THP for filesystems will collapse THP for files opened readonly and mapped with VM_EXEC. The intended usecase is to avoid TLB misses for large text segments. But it doesn't restrict the file types so a THP could be collapsed for a non-regular file, for example, block device, if it is opened readonly and mapped with EXEC permission. This may cause bugs, like [1] and [2]. This is definitely not the intended usecase, so just collapse THP for regular files in order to close the attack surface.

2021-10-29mm, thp: bail out early in collapse_file for writeback pageRongwei Wang1-1/+6
Currently collapse_file does not explicitly check PG_writeback, instead, page_has_private and try_to_release_page are used to filter writeback pages. This does not work for xfs with blocksize equal to or larger than pagesize, because in such case xfs has no page->private. This makes collapse_file bail out early for writeback page. Otherwise, xfs end_page_writeback will panic as follows. page:fffffe00201bcc80 refcount:0 mapcount:0 mapping:ffff0003f88c86a8 index:0x0 pfn:0x84ef32 aops:xfs_address_space_operations [xfs] ino:30000b7 dentry name:"libtest.so" flags: 0x57fffe0000008027(locked|referenced|uptodate|active|writeback) raw: 57fffe0000008027 ffff80001b48bc28 ffff80001b48bc28 ffff0003f88c86a8 raw: 0000000000000000 0000000000000000 00000000ffffffff ffff0000c3e9a000 page dumped because: VM_BUG_ON_PAGE(((unsigned int) page_ref_count(page) + 127u <= 127u)) page->mem_cgroup:ffff0000c3e9a000 ------------[ cut here ]------------ kernel BUG at include/linux/mm.h:1212!
