patches/linux/3.0.9/100-headers_install-fix-__packed-in-exported-kernel-head.patch
Allow multi-word "install" command.
Autoconf can determine that the correct install command includes flags,
e.g., "/usr/bin/install -c". When using this as a command, we can't
enclose the value in double-quotes, as that makes some shells use the
whole expression as a filename:
# this is the value returned by autoconf and stored in CT_install
$ ins="/usr/bin/install -c"
# if we call it with quotes, the command is not found
$ "${ins}"
bash: /usr/bin/install -c: No such file or directory
# removing the quotes lets it work as expected
$ ${ins}
/usr/bin/install: missing file operand
Try `/usr/bin/install --help' for more information.

5 headers_install: fix __packed in exported kernel headers
7 checkpatch.pl warns about using __attribute__((packed)) in kernel
8 headers: "__packed is preferred over __attribute__((packed))". If one
9 follows that advice it could cause problems in the exported header
10 files, because the outside world doesn't know about this shortcut.
12 For example busybox will fail to compile:
13 CC miscutils/ubi_attach_detach.o
14 In file included from miscutils/ubi_attach_detach.c:27:0:
15 /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’
16 /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here
19 Fix the problem by substituting __packed with __attribute__((packed)) in
20 the header_install.pl script.
