[klibc] [PATCH] fix ARM longjmp with zero 'val'.

[Thorsten Glaser]

Bill Pringlemeir dixit:

>make CROSS_COMPILE=arm-none-linux-gnueabi-
>KLIBCREQFLAGS='-mabi=aapcs-linux' ARCH=arm CPU_ARCH=armv5te
>CPU_TUNE=arm926ej-s KLIBCKERNELSRC=/home/src/linux/source
>KLIBCKERNELOBJ=/home/src/linux $*

>I just did a 'git diff' and attached that to my mail.  Is a 'git
>format-patch' the right way to do this?

Actually, 'git format-patch -s'. If you just want to do it for the
top (last commit), 'git format-patch -s HEAD^' is right. Then add
a To: header to the file and mail it out, for example like this:

(echo 'To: klibc at zytor.com'; git format-patch -s HEAD^) | sendmail -oem -oi -t

Yes, except it doesn’t really use the kernel config, only its
config system. The correct thing to do is to set the flag for
thumb to y, possibly on the command line. The Debian package,
for example, for armhf does this:

make ARCH=arm CONFIG_AEABI=y CPU_ARCH=armv7-a CPU_TUNE=cortex-a8 \
    CONFIG_KLIBC_THUMB=y INSTALLROOT=debian/tmp […]

Note that thumb was broken until last weekend.
