2020-08-19of: address: Work around missing device_type property in pcie nodesMarc Zyngier
Recent changes to the DT PCI bus parsing made it mandatory for device tree nodes describing a PCI controller to have the 'device_type = "pci"' property for the node to be matched. Although this follows the letter of the specification, it breaks existing device-trees that have been working fine for years. Rockchip rk3399-based systems are a prime example of such collateral damage, and have stopped discovering their PCI bus. In order to paper over it, let's add a workaround to the code matching the device type, and accept as PCI any node that is named "pcie", A warning will hopefully nudge the user into updating their DT to a fixed version if they can, but the incentive is obviously pretty small.

2020-08-19lib/string.c: Use freestanding environmentArvind Sankar
gcc can transform the loop in a naive implementation of memset/memcpy etc into a call to the function itself. This optimization is enabled by -ftree-loop-distribute-patterns. This has been the case for a while, but gcc-10.x enables this option at -O2 rather than -O3 as in previous versions. Add -ffreestanding, which implicitly disables this optimization with gcc. It is unclear whether clang performs such optimizations, but hopefully it will also not do so in a freestanding environment.

2020-08-19x86/boot/compressed: Use builtin mem functions for decompressorArvind Sankar
Since commits c041b5ad8640 ("x86, boot: Create a separate string.h file to provide standard string functions") fb4cac573ef6 ("x86, boot: Move memcmp() into string.h and string.c") the decompressor stub has been using the compiler's builtin memcpy, memset and memcmp functions, _except_ where it would likely have the largest impact, in the decompression code itself. Remove the #undef's of memcpy and memset in misc.c so that the decompressor code also uses the compiler builtins. The rationale given in the comment doesn't really apply: just because some functions use the out-of-line version is no reason to not use the builtin version in the rest. Replace the comment with an explanation of why memzero and memmove are being #define'd. Drop the suggestion to #undef in boot/string.h as well: the out-of-line versions are not really optimized versions, they're generic code that's good enough for the preboot environment. The compiler will likely generate better code for constant-size memcpy/memset/memcmp if it is allowed to. Most decompressors' performance is unchanged, with the exception of LZ4 and 64-bit ZSTD. Before After ARCH LZ4 73ms 10ms 32 LZ4 120ms 10ms 64 ZSTD 90ms 74ms 64 Measurements on QEMU on 2.2GHz Broadwell Xeon, using defconfig kernels. Decompressor code size has small differences, with the largest being that 64-bit ZSTD decreases just over 2k. The largest code size increase was on 64-bit XZ, of about 400 bytes.

2020-08-19io_uring: use system_unbound_wq for ring exit workJens Axboe
We currently use system_wq, which is unbounded in terms of number of workers. This means that if we're exiting tons of rings at the same time, then we'll briefly spawn tons of event kworkers just for a very short blocking time as the rings exit. Use system_unbound_wq instead, which has a sane cap on the concurrency level. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-08-19ext4: limit the length of per-inode prealloc listbrookxu
In the scenario of writing sparse files, the per-inode prealloc list may be very long, resulting in high overhead for ext4_mb_use_preallocated(). To circumvent this problem, we limit the maximum length of per-inode prealloc list to 512 and allow users to modify it. After patching, we observed that the sys ratio of cpu has dropped, and the system throughput has increased significantly. We created a process to write the sparse file, and the running time of the process on the fixed kernel was significantly reduced, as follows: Running time on unfixed kernel： [root@TENCENT64 ~]# time taskset 0x01 ./sparse /data1/sparce.dat real 0m2.051s user 0m0.008s sys 0m2.026s Running time on fixed kernel： [root@TENCENT64 ~]# time taskset 0x01 ./sparse /data1/sparce.dat real 0m0.471s user 0m0.004s sys 0m0.395s Signed-off-by: Chunguang Xu <brookxu@tencent.com> Link: https://lore.kernel.org/r/d7a98178-056b-6db5-6bce-4ead23f4a257@gmail.com Signed-off-by: Theodore Ts'o <tytso@mit.edu>

2020-08-19ALSA: hda: avoid reset of sdo_limitSameer Pujar
By default 'sdo_limit' is initialized with a default value of '8' as per spec. This is overridden in cases where a different value is required. However this is getting reset when snd_hdac_bus_init_chip() is called again, which happens during runtime PM cycle. Avoid this reset by moving 'sdo_limit' setup to 'snd_hdac_bus_init()' function which would be called only once.

2020-08-19drm/i915/tgl: Make sure TC-cold is blocked before enabling TC AUX power wellsImre Deak
The dependency between power wells is determined by the ordering of the power well list: when enabling the power wells for a domain, this happens walking the power well list forward, while disabling them happens in the reverse direction. Accordingly a power well on the list must follow any other power well it depends on. Since the TC AUX power wells depend on TC-cold being blocked, move the TC-cold off power well before all AUX power wells.

2020-08-19drm/i915/selftests: Avoid passing a random 0 into ilog2George Spelvin
igt_mm_config() calls ilog2() on the (pseudo)random 21-bit number s>>12. Once in 2 million seeds, this is zero and ilog2 summons the nasal demons. There was an attempt to handle this case with a max(), but that's too late; ms could already be something bizarre. Given that the low 12 bits of s and ms are always zero, it's a lot simpler just to divide them by 4096, then everything fits into 32 bits, and we can easily generate a random number 1 <= s <= 0x1fffff.

2020-08-18mm/memory.c: skip spurious TLB flush for retried page faultYang Shi
Recently we found regression when running will_it_scale/page_fault3 test on ARM64. Over 70% down for the multi processes cases and over 20% down for the multi threads cases. It turns out the regression is caused by commit 89b15332af7c ("mm: drop mmap_sem before calling balance_dirty_pages() in write fault"). The test mmaps a memory size file then write to the mapping, this would make all memory dirty and trigger dirty pages throttle, that upstream commit would release mmap_sem then retry the page fault. The retried page fault would see correct PTEs installed then just fall through to spurious TLB flush. The regression is caused by the excessive spurious TLB flush. It is fine on x86 since x86's spurious TLB flush is no-op. We could just skip the spurious TLB flush to mitigate the regression.

2020-08-18ext4: optimize the implementation of ext4_mb_good_group()brookxu
It might be better to adjust the code in two places: 1. Determine whether grp is currupt or not should be placed first. 2. (cr<=2 && free <ac->ac_g_ex.fe_len)should may belong to the crx strategy, and it may be more appropriate to put it in the subsequent switch statement block. For cr1, cr2, the conditions in switch potentially realize the above judgment. For cr0, we should add (free <ac->ac_g_ex.fe_len) judgment, and then delete (free / fragments) >= ac->ac_g_ex.fe_len), because cr0 returns true by default.
