2021-07-27arm64: mte: avoid TFSRE0_EL1 related operations unless in async modePeter Collingbourne1-9/+19
There is no reason to touch TFSRE0_EL1 nor issue a DSB unless our task is in asynchronous mode. Since these operations (especially the DSB) may be expensive on certain microarchitectures, only perform them if necessary. Furthermore, stop clearing TFSRE0_EL1 on entry because it will be cleared on exit and it is not necessary to have any particular value in TFSRE0_EL1 between entry and exit.

While there is no publicly available schematic of this board, it's not hard to determine voltage of GPIO port C, D and G (only ones which can be set). Port C and G are used for MMC/SDIO communication, so they use 1.8 V power supply. It's not clear if port D is even used, but if it is, it's pretty safe to assume it uses 3.3 V power supply. Value read from PIO Group Withstand Voltage Mode Select register from within pre-installed Android agrees with that assesment.

2021-07-23signal: Verify the alignment and size of siginfo_tEric W. Biederman2-0/+4
Update the static assertions about siginfo_t to also describe it's alignment and size. While investigating if it was possible to add a 64bit field into siginfo_t[1] it became apparent that the alignment of siginfo_t is as much a part of the ABI as the size of the structure. If the alignment changes siginfo_t when embedded in another structure can move to a different offset. Which is not acceptable from an ABI structure. So document that fact and add static assertions to notify developers if they change change the alignment by accident.

To get it over with once and for all, make all of this file uncondititonal now so it can be accessed everywhere. There are only a few types left that are in asm/compat.h but not yet in the asm-generic version, so add those in the process.

The straightforward one is a fix to our firmware calling stub, which accidentally started corrupting the link register on machines with SVE. Since these machines don't really exist yet, it wasn't spotted in -next. The other fix is a revert-and-a-bit of a patch originally intended to allow PTE-level huge mappings for the VMAP area on 32-bit PPC 8xx. A side-effect of this change was that our pXd_set_huge() implementations could be replaced with generic dummy functions depending on the levels of page-table being used, which in turn broke the boot if we fail to create the linear mapping as a result of using these functions to operate on the pgd. Huge thanks to Michael Ellerman for modifying the revert so as not to regress PPC 8xx in terms of functionality. Anyway, that's the background and it's also available in the commit message along with Link tags pointing at all of the fun.

2021-07-21Revert "mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge"Jonathan Marek1-12/+8
This reverts commit c742199a014de23ee92055c2473d91fe5561ffdf. c742199a014d ("mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge") breaks arm64 in at least two ways for configurations where PUD or PMD folding occur: 1. We no longer install huge-vmap mappings and silently fall back to page-granular entries, despite being able to install block entries at what is effectively the PGD level. 2. If the linear map is backed with block mappings, these will now silently fail to be created in alloc_init_pud(), causing a panic early during boot. The pgtable selftests caught this, although a fix has not been forthcoming and Christophe is AWOL at the moment, so just revert the change for now to get a working -rc3 on which we can queue patches for 5.15. A simple revert breaks the build for 32-bit PowerPC 8xx machines, which rely on the default function definitions when the corresponding page-table levels are folded, since commit a6a8f7c4aa7e ("powerpc/8xx: add support for huge pages on VMAP and VMALLOC"), eg: powerpc64-linux-ld: mm/vmalloc.o: in function `vunmap_pud_range': linux/mm/vmalloc.c:362: undefined reference to `pud_clear_huge' To avoid that, add stubs for pud_clear_huge() and pmd_clear_huge() in arch/powerpc/mm/nohash/8xx.c as suggested by Christophe.

2021-07-21drivers/firmware: consolidate EFI framebuffer setup for all archesJavier Martinez Canillas1-4/+1
The register_gop_device() function registers an "efi-framebuffer" platform device to match against the efifb driver, to have an early framebuffer for EFI platforms. But there is already support to do exactly the same by the Generic System Framebuffers (sysfb) driver. This used to be only for X86 but it has been moved to drivers/firmware and could be reused by other architectures. Also, besides supporting registering an "efi-framebuffer", this driver can register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers on non-X86 EFI platforms. For example, on aarch64 these drivers can only be used with DT and doesn't have code to register a "simple-frambuffer" platform device when booting with EFI. For these reasons, let's remove the register_gop_device() duplicated code and instead move the platform specific logic that's there to sysfb driver.

Also the USB-portB is used as the USB emergency download port (for image download purposes).
