Pull ARM fixes from Russell King: - Fix latent bug with DC21285 (Footbridge PCI bridge) configuration accessors that affects GCC >= 4.9.2 - Fix misplaced tegra_uart_config in decompressor - Ensure signal page contents are initialised - Fix kexec oops * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: kexec: fix oops after TLB are invalidated ARM: ensure the signal page contains defined contents ARM: 9043/1: tegra: Fix misplaced tegra_uart_config in decompressor ARM: footbridge: fix dc21285 PCI configuration accessors
2021-02-05ARM: kexec: fix oops after TLB are invalidatedRussell King4-39/+36
Giancarlo Ferrari reports the following oops while trying to use kexec: Unable to handle kernel paging request at virtual address 80112f38 pgd = fd7ef03e [80112f38] *pgd=0001141e(bad) Internal error: Oops: 80d [#1] PREEMPT SMP ARM ... This is caused by machine_kexec() trying to set the kernel text to be read/write, so it can poke values into the relocation code before copying it - and an interrupt occuring which changes the page tables. The subsequent writes then hit read-only sections that trigger a data abort resulting in the above oops. Fix this by copying the relocation code, and then writing the variables into the destination, thereby avoiding the need to make the kernel text read/write.

2021-02-03ARM: dts: lpc32xx: Revert set default clock rate of HCLK PLLAlexandre Belloni1-3/+0
This reverts commit c17e9377aa81664d94b4f2102559fcf2a01ec8e7. The lpc32xx clock driver is not able to actually change the PLL rate as this would require reparenting ARM_CLK, DDRAM_CLK, PERIPH_CLK to SYSCLK, then stop the PLL, update the register, restart the PLL and wait for the PLL to lock and finally reparent ARM_CLK, DDRAM_CLK, PERIPH_CLK to HCLK PLL. Currently, the HCLK driver simply updates the registers but this has no real effect and all the clock rate calculation end up being wrong. This is especially annoying for the peripheral (e.g. UARTs, I2C, SPI).

Non-existent nodes would mistaken get created with a leading '/'. The problem was fdt_path_offset() takes a full path while creating a node with fdt_add_subnode() takes just the basename.

2021-01-18ARM: dts: imx6qdl-sr-som: fix some cubox-i platformsRussell King1-2/+10
The PHY address bit 2 is configured by the LED pin. Attaching a LED to this pin is not sufficient to guarantee this configuration pin is correctly read. This leads to some platforms having their PHY at address 0 and others at address 4. If there is no phy-handle specified, the FEC driver will scan the PHY bus for a PHY and use that. Consequently, adding the DT configuration of the PHY and the phy properties to the FEC driver broke some boards. Fix this by removing the phy-handle property, and listing two PHY entries for both possible PHY addresses, so that the DT configuration for the PHY can be found by the PHY driver.

2021-01-15ARM: dts: ux500: Reserve memory carveoutsLinus Walleij4-1/+112
The Ux500 platforms have some memory carveouts set aside for communicating with the modem and for the initial secure software (ISSW). These areas are protected by the memory controller and will result in an external abort if accessed like common read/write memory. On the legacy boot loaders, these were set aside by using cmdline arguments such as this: mem=96M@0 mem_mtrace=15M@96M mem_mshared=1M@111M mem_modem=16M@112M mali.mali_mem=32M@128M mem=96M@160M hwmem=127M@256M mem_issw=1M@383M mem_ram_console=1M@384M mem=638M@385M Reserve the relevant areas in the device tree instead. The "mali", "hwmem", "mem_ram_console" and the trailing 1MB at the end of the memory reservations in the list are not relevant for the upstream kernel as these are nowadays replaced with upstream technologies such as CMA. The modem and ISSW reservations are necessary. This was manifested in a bug that surfaced in response to commit 7fef431be9c9 ("mm/page_alloc: place pages to tail in __free_pages_core()") which changes the behaviour of memory allocations in such a way that the platform will sooner run into these dangerous areas, with "Unhandled fault: imprecise external abort (0xc06) at 0xb6fd83dc" or similar: the real reason turns out to be that the PTE is pointing right into one of the reserved memory areas. We were just lucky until now. We need to augment the DB8500 and DB8520 SoCs similarly and also create a new include for the DB9500 used in the Snowball since this does not have a modem and thus does not need the modem memory reservation, albeit it needs the ISSW reservation.

2021-01-15drivers: bus: simple-pm-bus: Fix compatibility with simple-bus for auxdataTony Lindgren1-0/+1
After converting am335x to probe devices with simple-pm-bus I noticed that we are not passing auxdata for of_platform_populate() like we do with simple-bus. While device tree using SoCs should no longer need platform data, there are still quite a few drivers that still need it as can be seen with git grep OF_DEV_AUXDATA. We want to have simple-pm-bus be usable as a replacement for simple-bus also for cases where OF_DEV_AUXDATA is still needed. Let's fix the issue by passing auxdata as platform data to simple-pm-bus. That way the SoCs needing this can pass the auxdata with OF_DEV_AUXDATA. And let's pass the auxdata for omaps to fix the issue for am335x. As an alternative solution, adding simple-pm-bus handling directly to drivers/of/platform.c was considered, but we would still need simple-pm-bus device driver. So passing auxdata as platform data seems like the simplest solution.

2021-01-15ARM: OMAP2+: Fix booting for am335x after moving to simple-pm-busTony Lindgren1-14/+14
We now depend on SIMPLE_PM_BUS for probing devices. While we have it selected in omap2plus_defconfig, custom configs can fail if it's missing. As SIMPLE_PM_BUS depends on OF and PM, we must now select PM in Kconfig. We have already OF selected by ARCH_MULTIPLATFORM. Let's also drop the earlier PM dependency entries as suggested by Geert Uytterhoeven <geert@linux-m68k.org>.

2021-01-15ARM: OMAP2+: Fix suspcious RCU usage splats for omap_enter_idle_coupledTony Lindgren1-8/+8
We get suspcious RCU usage splats with cpuidle in several places in omap_enter_idle_coupled() with the kernel debug options enabled: RCU used illegally from extended quiescent state! ... (_raw_spin_lock_irqsave) (omap_enter_idle_coupled+0x17c/0x2d8) (omap_enter_idle_coupled) (cpuidle_enter_state) (cpuidle_enter_state_coupled) (cpuidle_enter) Let's use RCU_NONIDLE to suppress these splats. Things got changed around with commit 1098582a0f6c ("sched,idle,rcu: Push rcu_idle deeper into the idle path") that started triggering these warnings. For the tick_broadcast related calls, ideally we'd just switch over to using CPUIDLE_FLAG_TIMER_STOP for omap_enter_idle_coupled() to have the generic cpuidle code handle the tick_broadcast related calls for us and then just drop the tick_broadcast calls here. But we're currently missing the call in the common cpuidle code for tick_broadcast_enable() that CPU1 hotplug needs as described in earlier commit 50d6b3cf9403 ("ARM: OMAP2+: fix lack of timer interrupts on CPU1 after hotplug").

2021-01-13xen: Fix event channel callback via INTX/GSIDavid Woodhouse1-1/+1
For a while, event channel notification via the PCI platform device has been broken, because we attempt to communicate with xenstore before we even have notifications working, with the xs_reset_watches() call in xs_init(). We tend to get away with this on Xen versions below 4.0 because we avoid calling xs_reset_watches() anyway, because xenstore might not cope with reading a non-existent key. And newer Xen *does* have the vector callback support, so we rarely fall back to INTX/GSI delivery. To fix it, clean up a bit of the mess of xs_init() and xenbus_probe() startup. Call xs_init() directly from xenbus_init() only in the !XS_HVM case, deferring it to be called from xenbus_probe() in the XS_HVM case instead. Then fix up the invocation of xenbus_probe() to happen either from its device_initcall if the callback is available early enough, or when the callback is finally set up. This means that the hack of calling xenbus_probe() from a workqueue after the first interrupt, or directly from the PCI platform device setup, is no longer needed.

Commit 86cd97ec4b943af3 ("crypto: arm/chacha-neon - optimize for non-block size multiples") refactored the chacha block handling in the glue code in a way that may result in the counter increment to be omitted when calling chacha_block_xor_neon() to process a full block. This violates the skcipher API, which requires that the output IV is suitable for handling more input as long as the preceding input has been presented in round multiples of the block size. Also, the same code is exposed via the chacha library interface whose callers may actually rely on this increment to occur even for final blocks that are smaller than the chacha block size. So increment the counter after calling chacha_block_xor_neon().
