Subject	[PATCH 0/3] Hibernate cleanups
Date	Sat, 21 May 2011 14:08:28 +0200

Hi,

Following are three hibernate patches I didn't have the time to
work on before.

[1/3] - Update comments in kernel/power/hibernate.c
[2/3] - Remove arch_prepare_suspend()
[3/3] - Update kerneldoc comments in kernel/power/hibernate.c

Since they don't make any functional changes, I don't think it makes sense
to wait with them for the next merge window, so I'd like to push them
for 2.6.40 if no one objects.

Thanks,
Rafael

慘的是..後來 Linus 宣佈沒有 2.6.40，而是 3.0 ...

LKML 的 interface 很好心，會把相關的 repy-discuss 放在一個 tree (頁面的左邊)，每點一個 message，要是裡面包含 path，就會出現一個 "diff" 的link，讓你把 patch 拿下來。

這是samsung 基於那個 NOKIA initial work 所做的：

有提到那個 lds.S 修改。另外他還加上 A9 的 support。

還有 ，當 使用 eMMC /SD 作 resume partition 時，要等待 driver ready，所以

這個 patch 加上 resumewait 參數，等 dev open success..
