[PATCH 1/2] resolve clock_info reallocationg issue
From: Yong Shen
everytime when screen refresh, the clock_info data stucture will
be reacclocated, which does not make sence. This patch addresses

Thats wrong, you have to add the inotify_wd to the mainloop code.

I would suggest you create a clock_info structure where you store the
inotify_fd and inotify_wd and you use a clock_fini function.
struct clock_info *clock_info;
...
clock_info = clock_init();
...
clock_fini(clock_info);
...
That will prevent to add more global variables and extern definitions.
Pathes for "Produce boottarball that includes rootfs, kernel and bootloader" for Android
Hi, I will push some patches for review. They are all for Android. For the blueprint https://blueprints.launchpad.net/linaro-android/+spec/linaro-android-platform-kernel-boottarball . I have had problems setting the subject correctly, but they are for the android manifest, linaro/device/common, linaro/device/beagleboard and build gits.

Paull will bring this topic to the TSC to see whether they will be in support of handling Network device Drivers fix-ups and improvement. * Device Tree * All of the u-boot patches are in jcrigby's tree that covers omap3/4, samsung, freescale * On the kernel side efika, panda, overo, samsung and beagle support has been patched in and jcrigby will be pulling them into his stable tree * For Android - After alarmtimers is finished, John thinks lowmemorykiller would be a good area to look into. * Some of the kconfig Work Items will be POSTPONED to next cycle, as Jason will test kexec and John has to concentrate on Android kernel tree.

[PATCH android/frameworks/base] audioflinger: Enable ARMv5TE optimized resampler
Previously, the optimized asm option is only enabled when __ARM_ARCH_5E__ is defined, which is assigned in armv5te.mk rather than armv7-a series targets. This patch checks the ARM CPU feature about half-word multiply instructions to enable ARMv5TE resampler optimization routines properly.
