<title>uapi: export all headers under uapi directories</title>

<id>urn:sha1:fcc8487d477a3452a1d0ccbdd4c5e0e1e3cb8bed</id>
<content type='text'>
Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-blackfin/shmparam.h
asm-blackfin/ucontext.h
asm-c6x/shmparam.h
asm-c6x/ucontext.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).

Thanks to Julien Floret &lt;julien.floret@6wind.com&gt; for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/&lt;arch&gt;/include/uapi/asm/Kbuild;
 - arch/&lt;arch&gt;/include/asm/Kbuild.

It is used for limitation of buffer size during IOCTL such as FFU.
However, eMMC FW size is bigger than (512L*256).
(For instance, currently, Samsung eMMC FW size is over 300KB.)
So, it needs to increase to execute FFU.

<title>mmc: block: Add new ioctl to send multi commands</title>

<link rel='alternate' type='text/html' href='https://universe.0xinfinity.dev/distro/kernel/commit/?id=a5f5774c55a2e3ed75f4d6c5556b7bfcb726e6f0'/>
<id>urn:sha1:a5f5774c55a2e3ed75f4d6c5556b7bfcb726e6f0</id>
<content type='text'>
Certain eMMC devices allow vendor specific device information to be read
via a sequence of vendor commands. These vendor commands must be issued
in sequence and an atomic fashion. One way to support this would be to
add an ioctl function for sending a sequence of commands to the device
atomically as proposed here. These multi commands are simple array of
the existing mmc_ioc_cmd structure.

The structure passed via the ioctl uses a __u64 type to specify the number
of commands (so that the structure is aligned on a 64-bit boundary) and a
zero length array as a header for list of commands to be issued. The
maximum number of commands that can be sent is determined by
MMC_IOC_MAX_CMDS (which defaults to 255 and should be more than
sufficient).

This based upon work by Seshagiri Holi &lt;sholi@nvidia.com&gt;.
