clk: qcom: Fix PLL rate configurations

2014-10-05T20:41:12+00:00

commit 5b6b7490af110c2b0df807eddd00ae6290bcf50a upstream. Sometimes we need to program PLLs with a fixed rate configuration during driver probe. Doing this after we register the PLLs with the clock framework causes the common clock framework to assume the rate of the PLLs are 0. This causes all sorts of problems for rate recalculations because the common clock framework caches the rate once at registration time unless a flag is set to always recalculate the rates. Split the qcom_cc_probe() function into two pieces, map and everything else, so that drivers which need to configure some PLL rates or otherwise twiddle bits in the clock controller can do so before registering clocks. This allows us to properly detect the rates of PLLs that are programmed at boot.

clk: qcom: mdp_lut_clk is a child of mdp_src

2014-10-05T20:41:12+00:00

commit f87dfcabc6f173cc811d185d33327f50a8c88399 upstream. The mdp_lut_clk isn't a child of the mdp_clk. Instead it's the child of the mdp_src clock. Fix it.

clk: qcom: Fix MN frequency tables, parent map, and jpegd

2014-10-05T20:41:12+00:00

commit ff20783f7b9f35b29e768d8ecc7076c1ca1a60ca upstream. Clocks that don't have a pre-divider don't list any pre-divider in their frequency tables, but their tables are initialized using aggregate initializers. Use tagged initializers so we properly assign the m and n values for each frequency. Furthermore, the mmcc_pxo_pll8_pll2_pll3 array improperly mapped the second element to pll2 instead of pll8, causing the clock driver to recalculate the wrong rate for any clocks using this array along with a rate that uses pll2. Plus the .num_parents field is 3 instead of 4 so you can't even switch the parent to pll3. Finally I noticed that the jpegd clock improperly indicates that the pre-divider width is only 2, when it's actually 4 bits wide.

staging/lustre: disable virtual block device for 64K pages

2014-10-05T20:41:12+00:00

commit 0bf22be0da8ea74bc7ccc5b07d7855830be16eca upstream. The lustre virtual block device cannot handle 64K pages and fails at compile time. To avoid running into this error, let's disable the Kconfig option for this driver in cases it doesn't support.

ext4: avoid trying to kfree an ERR_PTR pointer

commit a9cfcd63e8d206ce4235c355d857c4fbdf0f4587 upstream. Thanks to Dan Carpenter for extending smatch to find bugs like this. (This was found using a development version of smatch.) Fixes: 36de928641ee48b2078d3fe9514242aaa2f92013 Reported-by: Dan Carpenter Signed-off-by: Greg Kroah-Hartman

ext4: propagate errors up to ext4_find_entry()'s callers

2014-10-05T20:41:12+00:00

commit 36de928641ee48b2078d3fe9514242aaa2f92013 upstream. If we run into some kind of error, such as ENOMEM, while calling ext4_getblk() or ext4_dx_find_entry(), we need to make sure this error gets propagated up to ext4_find_entry() and then to its callers. This way, transient errors such as ENOMEM can get propagated to the VFS. This is important so that the system calls return the appropriate error, and also so that in the case of ext4_lookup(), we return an error instead of a NULL inode, since that will result in a negative dentry cache entry that will stick around long past the OOM condition which caused a transient ENOMEM error.

aio: block exit_aio() until all context requests are completed

2014-10-05T20:41:12+00:00

commit 6098b45b32e6baeacc04790773ced9340601d511 upstream. It seems that exit_aio() also needs to wait for all iocbs to complete (like io_destroy), but we missed the wait step in current implemention, so fix it in the same way as we did in io_destroy.
