This series adds support for fast passive parallel (FPP) Altera
FPGA configuration using FTDI FT232H chip in FT245-FIFO mode.
It has been used to configure Arria 10 FPGAs.
Patch 1 adds an FT232H MFD driver with common functions that
can be used for FT232H USB-GPIO/I2C/SPI master adapter drivers.

There is an off-by-one bug here, which can cause host-to-guest write to stall.
When cur_write_sz == pending_sz, we shouldn't signal the host because it's
meaningless: the ring mustn't be 100% full.
But when cached_write_sz == pending_sz, we must signal the host.

Hi IRQ experts, DT exports,
I have a question about CONFIG_IRQ_DOMAIN_HIERARCHY.
When IRQ domains are hierarchy,
how can we specify IRQ number re-mapping between the
parent irqchip and the child irqchip?
The following figure shows a simplified example.

Hi!
I tried using git to clone kernel tree on N900, and could not figure
out how to do that. This machine has 256MB ram... more than enough for
kernel compilation, but apparently not enough for git.

This patch series adds support for building KASAN-enabled kernels with clang.
This mostly involves adding callbacks for a couple of new features in LLVM's
AddressSanitizer implementation. We also need to probe for the (slightly
different) CFLAGS used to configure ASAN with clang.
*** BLURB HERE *
Use cc-option to figure out whether the compiler's sanitizer uses
LLVM-style parameters ("-mllvm -asan-foo=bar") or GCC-style parameters
("--param asan-foo=bar").

clang's AddressSanitizer implementation adds redzones on either side of
alloca()ed buffers. These redzones are 32-byte aligned and at least 32
bytes long.
__asan_alloca_poison() is passed the size and address of the allocated
buffer, *excluding* the redzones on either side. The left redzone will

As a code-size optimization, LLVM builds since r279383 may
bulk-manipulate the shadow region when (un)poisoning large memory
blocks. This requires new callbacks that simply do an uninstrumented
memset().
This fixes linking the Clang-built kernel when using KASAN.

For now we can hard-code ASAN ABI level 5, since historical clang builds
can't build the kernel anyway. We also need to emulate gcc's
__SANITIZE_ADDRESS__ flag, or memset() calls won't be instrumented.

Hello,
The main change in this version is that the process of first trying to
verify a modsig and then trying an xattr sig if the former fails is now done
in ima_appraise_measurement instead of process_measurement. As a result, the
changes needed in the latter are small.
This is possible because
