Pull ARM SoC platform updates from Arnd Bergmann: "The APM X-Gene platform is now maintained by folks from Ampere computing that took over the product line a while ago, this gets reflected in the MAINTAINERS file. Cleanups continue on the older mach-davinci and mach-pxa platform, to get them to be more like the modern ones. For pxa, we now remove the Raumfeld platform code as it now works with device tree based booting. i.MX adds a couple new features for the i.MX7ULP SoC Mediatek gains support for a new SoC: MT7629 is a new wireless router platform, following MT7623.

2019-03-04get rid of legacy 'get_ds()' functionLinus Torvalds3-4/+2
Every in-kernel use of this function defined it to KERNEL_DS (either as an actual define, or as an inline function). It's an entirely historical artifact, and long long long ago used to actually read the segment selector valueof '%ds' on x86. Which in the kernel is always KERNEL_DS. Inspired by a patch from Jann Horn that just did this for a very small subset of users (the ones in fs/), along with Al who suggested a script. I then just took it to the logical extreme and removed all the remaining gunk. Roughly scripted with git grep -l '(get_ds())' -- :^tools/ | xargs sed -i 's/(get_ds())/(KERNEL_DS)/' git grep -lw 'get_ds' -- :^tools/ | xargs sed -i '/^#define get_ds()/d' plus manual fixups to remove a few unusual usage patterns, the couple of inline function cases and to fix up a comment that had become stale. The 'get_ds()' function remains in an x86 kvm selftest, since in user space it actually does something relevant.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground into timers/2038 Pull additional syscall ABI cleanup for y2038 from Arnd Bergmann: This is a follow-up to the y2038 syscall patches already merged in the tip tree. As the final 32-bit RISC-V syscall ABI is still being decided on, this is the last chance to make a few corrections to leave out interfaces based on 32-bit time_t along with the old off_t and rlimit types. The series achieves this in a few steps: - A couple of bug fixes for minor regressions I introduced in the original series - A couple of older patches from Yury Norov that I had never merged in the past, these fix up the openat/open_by_handle_at and getrlimit/setrlimit syscalls to disallow the old versions of off_t and rlimit. - Hiding the deprecated system calls behind an #ifdef in include/uapi/asm-generic/unistd.h - Change arch/riscv to drop all these ABIs. Originally, the plan was to also leave these out on C-Sky, but that now has a glibc port that uses the older interfaces, so we need to leave them in place.

Make the arm ctr-aes-ce algorithm update the IV buffer to contain the next counter after processing a partial final block, rather than leave it as the last counter. This makes ctr-aes-ce pass the updated AES-CTR tests. This change also makes the code match the arm64 version in arch/arm64/crypto/aes-modes.S more closely.

2019-02-22crypto: sha512/arm - fix crash bug in Thumb2 buildArd Biesheuvel2-2/+4
The SHA512 code we adopted from the OpenSSL project uses a rather peculiar way to take the address of the round constant table: it takes the address of the sha256_block_data_order() routine, and substracts a constant known quantity to arrive at the base of the table, which is emitted by the same assembler code right before the routine's entry point. However, recent versions of binutils have helpfully changed the behavior of references emitted via an ADR instruction when running in Thumb2 mode: it now takes the Thumb execution mode bit into account, which is bit 0 af the address. This means the produced table address also has bit 0 set, and so we end up with an address value pointing 1 byte past the start of the table, which results in crashes such as Unable to handle kernel paging request at virtual address bf825000 pgd = 42f44b11 [bf825000] *pgd=80000040206003, *pmd=5f1bd003, *pte=00000000 Internal error: Oops: 207 [#1] PREEMPT SMP THUMB2 Modules linked in: sha256_arm(+) sha1_arm_ce sha1_arm ...

2019-02-22crypto: sha256/arm - fix crash bug in Thumb2 buildArd Biesheuvel2-2/+4
The SHA256 code we adopted from the OpenSSL project uses a rather peculiar way to take the address of the round constant table: it takes the address of the sha256_block_data_order() routine, and substracts a constant known quantity to arrive at the base of the table, which is emitted by the same assembler code right before the routine's entry point. However, recent versions of binutils have helpfully changed the behavior of references emitted via an ADR instruction when running in Thumb2 mode: it now takes the Thumb execution mode bit into account, which is bit 0 af the address. This means the produced table address also has bit 0 set, and so we end up with an address value pointing 1 byte past the start of the table, which results in crashes such as Unable to handle kernel paging request at virtual address bf825000 pgd = 42f44b11 [bf825000] *pgd=80000040206003, *pmd=5f1bd003, *pte=00000000 Internal error: Oops: 207 [#1] PREEMPT SMP THUMB2 Modules linked in: sha256_arm(+) sha1_arm_ce sha1_arm ...

2019-02-20ARM: tegra: Restore DT ABI on Tegra124 ChromebooksThierry Reding1-1/+16
Commit 482997699ef0 ("ARM: tegra: Fix unit_address_vs_reg DTC warnings for /memory") inadventently broke device tree ABI by adding a unit- address to the "/memory" node because the device tree compiler flagged the missing unit-address as a warning. Tegra124 Chromebooks (a.k.a. Nyan) use a bootloader that relies on the full name of the memory node in device tree being exactly "/memory". It can be argued whether this was a good decision or not, and some other bootloaders (such as U-Boot) do accept a unit-address in the name of the node, but the device tree is an ABI and we can't break existing setups just because the device tree compiler considers it bad practice to omit the unit-address nowadays. This partially reverts the offending commit and restores device tree ABI compatibility.

Commit 3b79919946cd2cf4dac47842afc9a893acec4ed7 ("ARM: dts: armada-370-xp: update NAND node with new bindings") updated some Marvell Armada DT description to use the new NAND controller bindings, but did it incorrectly for a number of boards: armada-xp-gp, armada-xp-db and armada-xp-lenovo-ix4-300d. Due to this, the NAND is no longer detected on those platforms. This commit fixes that by properly using the new NAND DT binding. This commit was runtime-tested on Armada XP GP, the two other platforms are only compile-tested.

2019-02-1932-bit userspace ABI: introduce ARCH_32BIT_OFF_T config optionYury Norov1-0/+1
All new 32-bit architectures should have 64-bit userspace off_t type, but existing architectures has 32-bit ones. To enforce the rule, new config option is added to arch/Kconfig that defaults ARCH_32BIT_OFF_T to be disabled for new 32-bit architectures. All existing 32-bit architectures enable it explicitly. New option affects force_o_largefile() behaviour. Namely, if userspace off_t is 64-bits long, we have no reason to reject user to open big files. Note that even if architectures has only 64-bit off_t in the kernel (arc, c6x, h8300, hexagon, nios2, openrisc, and unicore32), a libc may use 32-bit off_t, and therefore want to limit the file size to 4GB unless specified differently in the open flags.

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.

Installing the appropriate non-IOMMU DMA ops in arm_iommu_detch_device() serves the case where IOMMU-aware drivers choose to control their own mapping but still make DMA API calls, however it also affects the case when the arch code itself tears down the mapping upon driver unbinding, where the ops now get left in place and can inhibit arch_setup_dma_ops() on subsequent re-probe attempts. Fix the latter case by making sure that arch_teardown_dma_ops() cleans up whenever the ops were automatically installed by its counterpart.
