Pull arm64 fixes from Catalin Marinas: - Set the minimum GCC version to 5.1 for arm64 due to earlier compiler bugs. - Make atomic helpers __always_inline to avoid a section mismatch when compiling with clang. - Fix the CMA and crashkernel reservations to use ZONE_DMA (remove the arm64_dma32_phys_limit variable, no longer needed with a dynamic ZONE_DMA sizing in 5.11). - Remove redundant IRQ flag tracing that was leaving lockdep inconsistent with the hardware state. - Revert perf events based hard lockup detector that was causing smp_processor_id() to be called in preemptible context. - Some trivial cleanups - spelling fix, renaming S_FRAME_SIZE to PT_REGS_SIZE, function prototypes added. * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: selftests: Fix spelling of 'Mismatch' arm64: syscall: include prototype for EL0 SVC functions compiler.h: Raise minimum version of GCC to 5.1 for arm64 arm64: make atomic helpers __always_inline arm64: rename S_FRAME_SIZE to PT_REGS_SIZE Revert "arm64: Enable perf events based hard lockup detector" arm64: entry: remove redundant IRQ flag tracing arm64: Remove arm64_dma32_phys_limit and its uses

Pull iommu fixes from Will Deacon: "Three IOMMU fixes for -rc4. The main one is a change to the Intel IOMMU driver to fix the handling of unaligned addresses when invalidating the TLB. The fix itself is a bit ugly (the caller does a bunch of shifting which is then effectively undone later in the callchain), but Lu has patches to clean all of this up in 5.12.

The kbuild test robot reports that when building with W=1, GCC will warn for a couple of missing prototypes in syscall.c: | arch/arm64/kernel/syscall.c:157:6: warning: no previous prototype for 'do_el0_svc' [-Wmissing-prototypes] | 157 | void do_el0_svc(struct pt_regs *regs) | | ^~~~~~~~~~ | arch/arm64/kernel/syscall.c:164:6: warning: no previous prototype for 'do_el0_svc_compat' [-Wmissing-prototypes] | 164 | void do_el0_svc_compat(struct pt_regs *regs) | | ^~~~~~~~~~~~~~~~~ While this isn't a functional problem, as a general policy we should include the prototype for functions wherever possible to catch any accidental divergence between the prototype and implementation. Here we can easily include <asm/exception.h>, so let's do so. While there are a number of warnings elsewhere and some warnings enabled under W=1 are of questionable benefit, this change helps to make the code more robust as it evolved and reduces the noise somewhat, so it seems worthwhile.

GCC versions >= 4.9 and < 5.1 have been shown to emit memory references beyond the stack pointer, resulting in memory corruption if an interrupt is taken after the stack pointer has been adjusted but before the reference has been executed. This leads to subtle, infrequent data corruption such as the EXT4 problems reported by Russell King at the link below. Life is too short for buggy compilers, so raise the minimum GCC version required by arm64 to 5.1.

UEFI/RM no longer use IED scripts from the VBIOS, though they appear to have been updated for use by the x86 VBIOS code, so we should be able to continue using them for the moment. Unfortunately, we require some hacks to do so, as the BeforeLinkTraining IED script became a pointer to an array of scripts instead, without a revbump of the relevant tables. There's also some changes to SOR clock divider fiddling, which are hopefully correct enough that things work as they should. AFAIK, GA100 shouldn't have display, so it hasn't been added.

Fortunately, all the interrupts we need to bring up basic display support are contained in a single leaf register, allowing this basic (but hackish) implementation. There's a bunch more invasive patches to come implementing all this in a better/more complete way, but trying to get a minimal series out first. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

This issue has generally been covered up by the presence of additional expansion ROMs after the ones we're interested in, with header fetches of subsequent images loading enough of the ROM to hide the issue. Noticed on GA102, which lacks a type 0x70 image compared to TU102,.
