[PATCH 6/11] drivers/dma: Correct NULL test
From: Julia Lawall <julia(a)diku.dk> cohd_fin has already been verified not to be NULL, so the argument to BUG_ON cannot be true. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression *x; expression e; identifier l; @@ if... 6 Feb 2010 04:15

[PATCH 11/11] fs/xfs: Correct NULL test

[PATCH 4/11] arch/x86/kvm: Correct NULL test

[PATCH 4/7] MTD: nand: make reads using MTD_OOB_RAW affect only ECC validation
This changes the behavier of MTD_OOB_RAW. It used to read both OOB and data to the data buffer, however you would still need to specify the dummy oob buffer. This is only used in one place, but makes it hard to read data+oob without ECC test, thus I removed that behavier, and fixed the user. Now MTD_OOB_RAW beh... 5 Feb 2010 18:26

[PATCHv4 0/2] sched: arch_scale_smt_powers
The new Power7 processor has 4 way SMT. This 4 way SMT benefits from dynamic power updates that arch_scale_smt_power was designed to provide. The first patch fixes a generic scheduler bug necessary for arch_scale_smt to properly function. The second patch implements arch_scale_smt_power for powerpc, and in parti... 5 Feb 2010 16:12
