Subject: Re: XTS Crypto Not Found In /proc/crypto Even After Compiled for 4.10.1.

OK, I just tried 4.10.0 and the output is looking the same.

I can't say my setup is all that odd. The cryptographic use is only
with the swap partition found in my original email (seen in Herbert's
reply).

My normal build goes as such:
1) git clean -xdf
2) git reset --hard
3) curl https://github.com/tobetter/linux/commit/9cdf86bac1db2d74bf98508226e86679581f8f80.patch
| git apply -
   //usb: host: xhci-plat: Get PHYs for xhci's hcds
4) curl https://github.com/tobetter/linux/commit/142cf1b68fa0e1710f3623875d5c269cbbc2f005.patch
| git apply -
   //base: platform: name the device already during allocation
5) curl https://github.com/tobetter/linux/commit/3772f11d73289ea40825f40ba5c64b5b0e3888ff.patch
| git apply -
   //phy: exynos5-usbdrd: Calibrate LOS levels for exynos5420/5800
6) sed -i -e "s/static void exynos5420_usbdrd_phy_calibrate/static int
exynos5420_usbdrd_phy_calibrate/" ./drivers/phy/phy-exynos5-usbdrd.c
7) //duplicate entry in drivers/media/usb/au0828/au0828-cards.c for my
0x400 vid tuner.
8) HOST_EXTRACFLAGS="-O3 -pipe -mfpu=neon-vfpv4 -mfloat-abi=hard
-march=armv7-a -mtune=cortex-a15.cortex-a7" make -j 8 zImage
exynos5422-odroidxu4.dtb modules 2>&1 | tee make.log
9) INSTALL_MOD_PATH=./tmp INSTALL_FW_PATH=./tmp make modules_install
firmware_install 2>&1 | tee makeModFirm.log
10) sudo cp -rv ./tmp/lib/* /usr/lib
11) sudo cp -v ./arch/arm/boot/zImage /boot/zImage-4.10.0
12) sudo cp -v ./arch/arm/boot/dts/exynos5422-odroidxu4.dtb
/boot/exynos5422-odroidxu4-4.10.0.dtb
13) sudo ln -s /boot/zImage-4.10.0 /boot/zImage
14) sudo ln -s /boot/exynos5422-odroidxu4-4.10.0.dtb
/boot/exynos5422-odroidxu4.dtb
15) sudo sync
16) sudo systemctl reboot

I've attached the config I use.
