Merge tag 'riscv-for-linus-4.20-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux

Pull RISC-V fixes from Palmer Dabbelt:
"This week is a bit bigger than I expected. That's my fault, as I
missed a few patches while I was at Plumbers last week. We have:

- A fix to a quite embarassing issue where raw_copy_to_user() was
implemented with asm_copy_from_user() (and vice versa).

- Improvements to our makefile to allow flat binaries to be
generated.

- A build fix that predeclares "struct module" at the top of
<asm/module.h>, which triggers warnings later in that header.

- The addition of our own <uapi/asm/unistd> header, which is
necessary to align our stat ABI on 32-bit systems.

- A fix to avoid printing a warning when the S or U bits are set in
print_isa().

I already have one patch in the queue for next week"

RISC-V: Build flat and compressed kernel images

This patch extends Linux RISC-V build system to build and install:
Image - Flat uncompressed kernel image
Image.gz - Flat and GZip compressed kernel image

Quiet a few bootloaders (such as Uboot, UEFI, etc) are capable of
booting flat and compressed kernel images. In case of Uboot, booting
Image or Image.gz is achieved using bootm command.

The flat and uncompressed kernel image (i.e. Image) is very useful
in pre-silicon developent and testing because we can create back-door
HEX files for RAM on FPGAs from Image.
