riscv: Fix early ftrace nop patching

commit 6ca445d8af0ed5950ebf899415fd6bfcd7d9d7a3 upstream.

Commit c97bf629963e ("riscv: Fix text patching when IPI are used")
converted ftrace_make_nop() to use patch_insn_write() which does not
emit any icache flush relying entirely on __ftrace_modify_code() to do
that.

But we missed that ftrace_make_nop() was called very early directly when
converting mcount calls into nops (actually on riscv it converts 2B nops
emitted by the compiler into 4B nops).

This caused crashes on multiple HW as reported by Conor and Björn since
the booting core could have half-patched instructions in its icache
which would trigger an illegal instruction trap: fix this by emitting a
local flush icache when early patching nops.

mm: Introduce flush_cache_vmap_early()

[ Upstream commit 7a92fc8b4d20680e4c20289a670d8fca2d1f2c1b ]

mm: Introduce flush_cache_vmap_early()

[ Upstream commit 7a92fc8b4d20680e4c20289a670d8fca2d1f2c1b ]

The pcpu setup when using the page allocator sets up a new vmalloc
mapping very early in the boot process, so early that it cannot use the
flush_cache_vmap() function which may depend on structures not yet
initialized (for example in riscv, we currently send an IPI to flush
other cpus TLB).

But on some architectures, we must call flush_cache_vmap(): for example,
in riscv, some uarchs can cache invalid TLB entries so we need to flush
the new established mapping to avoid taking an exception.

So fix this by introducing a new function flush_cache_vmap_early() which
is called right after setting the new page table entry and before
accessing this new mapping. This new function implements a local flush
tlb on riscv and is no-op for other architectures (same as today).

Merge patch series "riscv: Reduce ARCH_KMALLOC_MINALIGN to 8"

Currently, riscv defines ARCH_DMA_MINALIGN as L1_CACHE_BYTES, I.E
64Bytes, if CONFIG_RISCV_DMA

Merge patch series "riscv: Reduce ARCH_KMALLOC_MINALIGN to 8"

Jisheng Zhang <jszhang@kernel.org> says:

Currently, riscv defines ARCH_DMA_MINALIGN as L1_CACHE_BYTES, I.E
64Bytes, if CONFIG_RISCV_DMA_NONCOHERENT=y. To support unified kernel
Image, usually we have to enable CONFIG_RISCV_DMA_NONCOHERENT, thus
it brings some bad effects to coherent platforms:

Firstly, it wastes memory, kmalloc-96, kmalloc-32, kmalloc-16 and
kmalloc-8 slab caches don't exist any more, they are replaced with
either kmalloc-128 or kmalloc-64.

Secondly, larger than necessary kmalloc aligned allocations results
in unnecessary cache/TLB pressure.

This issue also exists on arm64 platforms. From last year, Catalin
tried to solve this issue by decoupling ARCH_KMALLOC_MINALIGN from
ARCH_DMA_MINALIGN, limiting kmalloc() minimum alignment to
dma_get_cache_alignment() and replacing ARCH_KMALLOC_MINALIGN usage
in various drivers with ARCH_DMA_MINALIGN etc.[1]

One fact we can make use of for riscv: if the CPU doesn't support
ZICBOM or T-HEAD CMO, we know the platform is coherent. Based on
Catalin's work and above fact, we can easily solve the kmalloc align
issue for riscv: we can override dma_get_cache_alignment(), then let
it return ARCH_DMA_MINALIGN at the beginning and return 1 once we know
the underlying HW neither supports ZICBOM nor supports T-HEAD CMO.

So what about if the CPU supports ZICBOM or T-HEAD CMO, but all the
devices are dma coherent? Well, we use ARCH_DMA_MINALIGN as the
kmalloc minimum alignment, nothing changed in this case. This case
can be improved in the future once we see such platforms in mainline.

After this patch, a simple test of booting to a small buildroot rootfs
on qemu shows:

kmalloc-96 5041 5041 96 ...
kmalloc-64 9606 9606 64 ...
kmalloc-32 5128 5128 32 ...
kmalloc-16 7682 7682 16 ...
kmalloc-8 10246 10246 8 ...

So we save about 1268KB memory. The saving will be much larger in normal
OS env on real HW platforms.

patch1 allows kmalloc() caches aligned to the smallest value.
patch2 enables DMA_BOUNCE_UNALIGNED_KMALLOC.

After this series:

As for coherent platforms, kmalloc-{8,16,32,96} caches come back on
coherent both RV32 and RV64 platforms, I.E !ZICBOM and !THEAD_CMO.

As for noncoherent RV32 platforms, nothing changed.

As for noncoherent RV64 platforms, I.E either ZICBOM or THEAD_CMO, the
above kmalloc caches also come back if > 4GB memory or users pass
"swiotlb=mmnn,force" to force swiotlb creation if <= 4GB memory. How
much mmnn should be depends on the specific platform, it needs to be
tried and tested all possible usage case on the specific hardware. For
example, I can use the minimal I/O TLB slabs on Sipeed M1S Dock.

Merge tag 'riscv-for-linus-6.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V fixes from Palmer Dabbelt:

- Fixes for a pair of kexec_file_load() failures

- A fix to ensure the direct mapping is PMD-aligned

- A fix for CPU feature detection on SMP=n

- The MMIO ordering fences have been strengthened to ensure ordering
WRT delay()

- Fixes for a pair of -Wmissing-variable-declarations warnings

- A fix to avoid PUD mappings in vmap on sv39

- flush_cache_vmap() now flushes the TLB to avoid issues on systems
that cache invalid mappings

riscv: Implement flush_cache_vmap()

The RISC-V kernel needs a sfence.vma after a page table modification: we
used to rely on the vmalloc fault handling to emit an sfence.vma, but
commit 7d3332be011e

riscv: Implement flush_cache_vmap()

The RISC-V kernel needs a sfence.vma after a page table modification: we
used to rely on the vmalloc fault handling to emit an sfence.vma, but
commit 7d3332be011e ("riscv: mm: Pre-allocate PGD entries for
vmalloc/modules area") got rid of this path for 64-bit kernels, so now we
need to explicitly emit a sfence.vma in flush_cache_vmap().

Note that we don't need to implement flush_cache_vunmap() as the generic
code should emit a flush tlb after unmapping a vmalloc region.
