2019-09-11mmc: sdhci-of-aspeed: Add support for the ASPEED SD controllerAndrew Jeffery
Add a minimal driver for ASPEED's SD controller, which exposes two SDHCIs. The ASPEED design implements a common register set for the SDHCIs, and moves some of the standard configuration elements out to this common area (e.g. 8-bit mode, and card detect configuration which is not currently supported). The SD controller has a dedicated hardware interrupt that is shared between the slots. The common register set exposes information on which slot triggered the interrupt; early revisions of the patch introduced an irqchip for the register, but reality is it doesn't behave as an irqchip, and the result fits awkwardly into the irqchip APIs. Instead I've taken the simple approach of using the IRQ as a shared IRQ with some minor performance impact for the second slot. Ryan was the original author of the patch - I've taken his work and massaged it to drop the irqchip support and rework the devicetree integration. The driver has been smoke tested under qemu against a minimal SD controller model and lightly tested on an ast2500-evb.

All R-Car Gen3 SoCs with any ES version cannot use this DMAC actually. So, this patch removes the compatibles of R-Car Gen3 SoCs from renesas_sdhi_sys_dmac_of_match. Since the previous code has an empty whitelist to prevent probing of R-Car Gen3 SoCs, no behavior changes.

2019-09-11mmc: sdhci-cadence: use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct sdhci_cdns_priv { ... struct sdhci_cdns_phy_param phy_params[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*priv) + sizeof(priv->phy_params[0]) * nr_phy_params with: struct_size(priv, phy_params, nr_phy_params) Also, notice that, in this case, variable priv_size is not necessary, hence it is removed.

The code dealing with busy detection is somewhat complicated. In a way to make it a bit clearer, let's try to clarify the comments in the code about it. Additionally, move the part for clearing the so called busy start IRQ, to the place where the IRQ is actually delivered. Ideally, this should make the code a bit more robust. Finally, to improve understanding of the code and the sequence of the busy detection, move the corresponding code around a bit in mmci_cmd_irq().

GCC unescapes escaped string section names while Clang does not. Because __section uses the `#` stringification operator for the section name, it doesn't need to be escaped.

2019-09-07Revert "x86/apic: Include the LDR when clearing out APIC registers"Linus Torvalds
This reverts commit 558682b5291937a70748d36fd9ba757fb25b99ae. Chris Wilson reports that it breaks his CPU hotplug test scripts. In particular, it breaks offlining and then re-onlining the boot CPU, which we treat specially (and the BIOS does too). The symptoms are that we can offline the CPU, but it then does not come back online again: smpboot: CPU 0 is now offline smpboot: Booting Node 0 Processor 0 APIC 0x0 smpboot: do_boot_cpu failed(-1) to wakeup CPU#0 Thomas says he knows why it's broken (my personal suspicion: our magic handling of the "cpu0_logical_apicid" thing), but for 5.3 the right fix is to just revert it, since we've never touched the LDR bits before, and it's not worth the risk to do anything else at this stage. [ Hotpluging of the boot CPU is special anyway, and should be off by default. See the "BOOTPARAM_HOTPLUG_CPU0" config option and the cpu0_hotplug kernel parameter. In general you should not do it, and it has various known limitations (hibernate and suspend require the boot CPU, for example). But it should work, even if the boot CPU is special and needs careful treatment - Linus ] Link: https://lore.kernel.org/lkml/156785100521.13300.14461504732265570003@skylake-alporthouse-com/ Reported-by: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Thomas Gleixner <tglx@linutronix.de> Cc: Bandan Das <bsd@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2019-09-06soc: qcom: geni: Provide parameter error checkingLee Jones
When booting with ACPI, the Geni Serial Engine is not set as the I2C/SPI parent and thus, the wrapper (parent device) is unassigned. This causes the kernel to crash with a null dereference error.

2019-09-06iommu/amd: Fix race in increase_address_space()Joerg Roedel
After the conversion to lock-less dma-api call the increase_address_space() function can be called without any locking. Multiple CPUs could potentially race for increasing the address space, leading to invalid domain->mode settings and invalid page-tables. This has been happening in the wild under high IO load and memory pressure. Fix the race by locking this operation. The function is called infrequently so that this does not introduce a performance regression in the dma-api path again.

2019-09-06iommu/amd: Flush old domains in kdump kernelStuart Hayes
When devices are attached to the amd_iommu in a kdump kernel, the old device table entries (DTEs), which were copied from the crashed kernel, will be overwritten with a new domain number. When the new DTE is written, the IOMMU is told to flush the DTE from its internal cache--but it is not told to flush the translation cache entries for the old domain number. Without this patch, AMD systems using the tg3 network driver fail when kdump tries to save the vmcore to a network system, showing network timeouts and (sometimes) IOMMU errors in the kernel log. This patch will flush IOMMU translation cache entries for the old domain when a DTE gets overwritten with a new domain number.

2019-09-05keys: Fix missing null pointer check in request_key_auth_describe()Hillf Danton
If a request_key authentication token key gets revoked, there's a window in which request_key_auth_describe() can see it with a NULL payload - but it makes no check for this and something like the following oops may occur: BUG: Kernel NULL pointer dereference at 0x00000038 Faulting instruction address: 0xc0000000004ddf30 Oops: Kernel access of bad area, sig: 11 [#1] ...
