SPDX changes for 6.0-rc1
Here is the set of SPDX comment updates for 6.0-rc1. Nothing huge here, just a number of updated SPDX license tags and cleanups based on the review of a number of common patterns in GPLv2 boilerplate text. Also included in here are a few other minor updates, 2 USB files, and one Documentation file update to get the SPDX lines correct. All of these have been in the linux-next tree for a very long time.

Driver core / kernfs changes for 6.0-rc1
Here is the set of driver core and kernfs changes for 6.0-rc1. "biggest" thing in here is some scalability improvements for kernfs for large systems.

RCU pull request for v5.20 (or whatever)
This pull request contains the following branches: doc.2022.06.21a: Documentation updates. fixes.2022.07.19a: Miscellaneous fixes. nocb.2022.07.19a: Callback-offload updates, perhaps most notably a new RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to be offloaded at boot time, regardless of kernel boot parameters. This is useful to battery-powered systems such as ChromeOS and Android. In addition, a new RCU_NOCB_CPU_CB_BOOST kernel boot parameter prevents offloaded callbacks from interfering with real-time workloads and with energy-efficiency mechanisms. poll.2022.07.21a: Polled grace-period updates, perhaps most notably making these APIs account for both normal and expedited grace periods. rcu-tasks.2022.06.21a: Tasks RCU updates, perhaps most notably reducing the CPU overhead of RCU tasks trace grace periods by more than a factor of two on a system with 15,000 tasks. The reduction is expected to increase with the number of tasks, so it seems reasonable to hypothesize that a system with 150,000 tasks might see a 20-fold reduction in CPU overhead. torture.2022.06.21a: Torture-test updates. ctxt.2022.07.05a: Updates that merge RCU's dyntick-idle tracking into context tracking, thus reducing the overhead of transitioning to kernel mode from either idle or nohz_full userspace execution for kernels that track context independently of RCU.

Here's a summary of the various patches: - The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot option have been removed, as they overlapped with the more widely supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and "random.trust_cpu". This change allowed simplifying a bit of arch code. - x86's RDRAND boot time test has been made a bit more robust, with RDRAND disabled if it's clearly producing bogus results. This would be a tip.git commit, technically, but I took it through random.git to avoid a large merge conflict. - The RNG has long since mixed in a timestamp very early in boot, on the premise that a computer that does the same things, but does so starting at different points in wall time, could be made to still produce a different RNG state. Unfortunately, the clock isn't set early in boot on all systems, so now we mix in that timestamp when the time is actually set. - User Mode Linux now uses the host OS's getrandom() syscall to generate a bootloader RNG seed and later on treats getrandom() as the platform's RDRAND-like faculty. - The arch_get_random_{seed_,}_long() family of functions is now arch_get_random_{seed_,}_longs(), which enables certain platforms, such as s390, to exploit considerable performance advantages from requesting multiple CPU random numbers at once, while at the same time compiling down to the same code as before on platforms like x86. - A small cleanup changing a cmpxchg() into a try_cmpxchg(), from Uros. - A comment spelling fix" More info about other random number changes that come in through various architecture trees in the full commentary in the pull request: https://lore.kernel.org/all/20220731232428.2219258-1-Jason@zx2c4.com/ * tag 'random-6.0-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: correct spelling of "overwrites" random: handle archrandom with multiple longs um: seed rng using host OS rng random: use try_cmpxchg in _credit_init_bits timekeeping: contribute wall clock to rng on time change x86/rdrand: Remove "nordrand" flag in favor of "random.trust_cpu" random: remove CONFIG_ARCH_RANDOM |

ARM: SoC defconfig updates for 6.0
This branch includes the usual updates to defconfig files, enabling additional driver support for the supported platforms. There is also a global refresh for all of them that reorders the lines according to the 'savedefconfig' output, but without removing lines that are no longer part of the refresh. I went through the most common removed lines to also address them while making sure to catch renamed options and add them back under the new name. The boardfile deprecation branch is based on top of this to avoid conflicts against removing the unused boardfile configs from the generic defconfig files. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmLo+14ACgkQmmx57+YA GNnFGw/+Ml2Jich+21ZIcgcAHjrMXq89lCoRa+3clGcxjDl97ZshNumqmRlgXqhM SlcqoA8gxFzx6SAFkCgxmi2m3+Cf8041VglM9YG9zcQnKxvcaRmAnLJ6X8ruwrRy OLHimRi187Wp33c4Y4On0s51g+F+cDHAJA9zmAoGISqPCluTkh/QeD9LXWSfBvFI 6203Hpbge69WzOL520zW7DBaLIRNL8qxSL3Pau6VUwHm2I2GvJ1WHE1S5kQwrd1a LKERfZswaBQtV3RJFRPigEqXzdzWAnD6XBLe1idGzaU52YAY6pxqQHTzOeVxlEPP m+w4jN6wEGK+iu8f0hjEnfr2qtM1Qx45UCvmg+tyY7WIwMWN304WDi+vgCpXPUWp W+IZNk6KPY9Bd3OauFtsiHHz9xXALidJRJT2JojnKDnQKK9J/iTpnBU2fPbpDNiC XOWcbm6e2R7U34LZZE2ursVqPk1iklXfb49/A+nl2x4MkxeX2va1QgyqJf6T6I9y 1avFY4V62lWvrEEMyKu+d7lpRKs3gj0Ky8W/R6+zLlnh4R2r9R+/BJAWi1MiP7qU ZpqWPc7m6cJcUC8Jgf2k+sDG8FNUWn0o6LNbCgv1m5GEYzzr1K9b3+KKV5JB1A9C Hjz9NMRXEOHm+QNvmbgXpCZjx9ga3Av+XAKN4pZ7JG9gc8fnrp0= =2GbW -----END PGP SIGNATURE----- Merge tag 'arm-defconfig-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC defconfig updates from Arnd Bergmann: "This branch includes the usual updates to defconfig files, enabling additional driver support for the supported platforms.

ARM: DT changes for 6.0
As usual, the bulk of the changes for the SoC tree are devicetree file updates, and most of these changes are for 64-bit embedded machines. As before, there are a ton of style cleanups, and additional hardware support for existing machines. Looking only at the new SoC, the notable additions are: - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit: BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146, BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes with a corresponding reference board. - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65 NPU. - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets added here in addition to the reference boards. - Allwinner H616, a newer version of the H6 SoC, targeted at Set-top-box applications. It comes with dts files for the Orange Pi zero2 single-board computer and the X96 Mate set-top-box - Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip in the Armada SoC family based on the Cortex-A55 core. New machines based on previously supported SoCs include: - Several new machines on NXP i.MX platforms: multiple Toradex Colibri boards using the "Iris" and "Ixora" carriers, DH electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems TQMa8MPQL, and phytech phyBOARD-Polis-i.MX8MM. - Google Chameleon v3 FPGA board based on Intel Arria10 and Stratix 10 Software Virtual platform, both in the SoCFPGA platform. - Two new wireless devices based on Broadcom SoCs: The Asus GT-AX6000 Router and the Cisco Meraki MR26 access point - Improved Chromebook support for both the Mediatek and Qualcomm SoC families brought added machines: Acer Chromebook 514 (MT8192), Acer Chromebook Spin 513 (MT8195) and a couple of SC7180 based machines including the Lenovo IdeaPad Chromebook Duet 3. - Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on Qualcomm SDM845, while Mi 5s Plus is based on MSM8996. - Finally, there are a few development board on other chips: PCB8309 (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308) DH DRC Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm SDM660) -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmLo+7MACgkQmmx57+YA GNlTQQ//QnOoW3fl2l4TvuBuP1Vxp7KW3GxZEkWBEfy7lfgkfBzksJ2GT+c96fxk +XEvSJcDsSo8zNYXXu/q0jjVKW4lEkiBtaB53NbLayNTFtJccKPiL4hccUkwSg1K zOhfu6SEgkwuYNAhtcQOfIec+gdF2PvpZSWUfuGvM2Z3rNhhyfhgoRRZCpc62eeS VQ+bVJH/7hG4XAJEcwmNK+8GoCcLbOclCa14oa9/LuEVjfYwOblfPjSflmfALzbM BoTDdeMbZoOdy3LOmLpT26Wv7zWQxLhTpiSYiSV0CI4NHUfzJj8ncNh+w9OiN+KO Z7cblHhveW5WSEP/jDp9YTf2XXA5UgpFQQjuXS8zQVECw5YxrSBB96GroQhvpcmT oSS0BVvlmp5snBRx4Oev2ldJ0BuyYYljF0DmmTrQ6s2gvB4WBlRSqplCAkDy59Im +mc5BBTqZYoxzCpzXEZR7VPzk1jzAO5wnYYd1mLJSHVExlSw8CQijy1a4YXxsvmK 4Sysrm8UbmPN/0anbiyPKeIkuNuufFUvUCR3Vm2HnMzNPza8YBJ0xm6zr8J7ecXe QcucpXyLi17GTLOm+pcyj2fQ19yVqO3xbutP4sy9StctEXLZe3rH2hY+GPK6N+Uj 83MbABMCmpUAyPMzR0AwTKx/RwWbf1jjYvcKg2VW8NNV5kkQQzM= =X6mA -----END PGP SIGNATURE----- Merge tag 'arm-dt-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM DT updates from Arnd Bergmann: "As usual, the bulk of the changes for the SoC tree are devicetree file updates, and most of these changes are for 64-bit embedded machines.

This was a fairly quiet cycle for the locking subsystem:

MODULE_LICENSE("GPL");
The root cause of the bug sits in neon_poly1305_blocks. The logic
neon_poly1305_blocks() performed is that if it was called with both s[]
and r[] uninitialized, it will first try to initialize them with the
data from the first "block" that it believed to be 32 bytes in length.
First 16 bytes are used as the key and the next 16 bytes for s[]. This
would lead to the aforementioned read out-of-bound. However, after
calling poly1305_init_arch(), only 16 bytes were deducted from the input
and s[] is initialized yet again with the following 16 bytes. The second
initialization of s[] is certainly redundent which indicates that the
first initialization should be for r[] only.
This patch fixes the issue by calling poly1305_init_arm64() instead of
poly1305_init_arch(). This is also the implementation for the same
algorithm on arm platform.
Fixes:

random: handle archrandom with multiple longs
The archrandom interface was originally designed for x86, which supplies RDRAND/RDSEED for receiving random words into registers, resulting in one function to generate an int and another to generate a long. However, other architectures don't follow this. On arm64, the SMCCC TRNG interface can return between one and three longs. On s390, the CPACF TRNG interface can return arbitrary amounts, with four longs having the same cost as one. On UML, the os_getrandom() interface can return arbitrary amounts. So change the api signature to take a "max_longs" parameter designating the maximum number of longs requested, and then return the number of longs generated. Since callers need to check this return value and loop anyway, each arch implementation does not bother implementing its own loop to try again to fill the maximum number of longs. Additionally, all existing callers pass in a constant max_longs parameter. Taken together, these two things mean that the codegen doesn't really change much for one-word-at-a-time platforms, while performance is greatly improved on platforms such as s390.

arm64: Delay initialisation of cpuinfo_arm64::reg_{zcr,smcr}
Even if we are now able to tell the kernel to avoid exposing SVE/SME from the command line, we still have a couple of places where we unconditionally access the ZCR_EL1 (resp. SMCR_EL1) registers. On systems with broken firmwares, this results in a crash even if arm64.nosve (resp. arm64.nosme) was passed on the command-line. To avoid this, only update cpuinfo_arm64::reg_{zcr,smcr} once we have computed the sanitised version for the corresponding feature registers (ID_AA64PFR0 for SVE, and ID_AA64PFR1 for SME). This results in some minor refactoring.

ARM: defconfig: address renamed CONFIG_DEBUG_INFO=y
CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.
This was actually not what I had in mind when I suggested making
it a 'choice' statement, but it's too late to change again now,
and the Kconfig logic is more sensible in the new form.
Change any defconfig file that had CONFIG_DEBUG_INFO enabled
but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain
default.

bpf, arm64: Fix compile error in dummy_tramp()
dummy_tramp() uses "lr" to refer to the x30 register, but some assembler
does not recognize "lr" and reports a build failure:
/tmp/cc52xO0c.s: Assembler messages:
/tmp/cc52xO0c.s:8: Error: operand 1 should be an integer register -- `mov lr,x9'
/tmp/cc52xO0c.s:7: Error: undefined symbol lr used as an immediate value
make[2]: *** [scripts/Makefile.build:250: arch/arm64/net/bpf_jit_comp.o] Error 1
make[1]: *** [scripts/Makefile.build:525: arch/arm64/net] Error 2
So replace "lr" with "x30" to fix it.

arm64/cpufeature: Store elf_hwcaps as a bitmap rather than unsigned long
When we added support for AT_HWCAP2 we took advantage of the fact that we have limited hwcaps to the low 32 bits and stored it along with AT_HWCAP in a single unsigned integer. Thanks to the ever expanding capabilities of the architecture we have now allocated all 64 of the bits in an unsigned long so in preparation for adding more hwcaps convert elf_hwcap to be a bitmap instead, with 64 bits allocated to each AT_HWCAP. There should be no functional change from this patch.

arm64: errata: Remove AES hwcap for COMPAT tasks
Cortex-A57 and Cortex-A72 have an erratum where an interrupt that occurs between a pair of AES instructions in aarch32 mode may corrupt the ELR. The task will subsequently produce the wrong AES result. The AES instructions are part of the cryptographic extensions, which are optional. User-space software will detect the support for these instructions from the hwcaps. If the platform doesn't support these instructions a software implementation should be used. Remove the hwcap bits on affected parts to indicate user-space should not use the AES instructions.
