The header files for the Pb1200/DBAu1200 boards have wrong definition for the
IDE interface's decoded range length -- it should be 512 bytes according to
what the IDE driver does. In addition, the IDE platform device claims 1 byte
too many for its memory resource -- fix the platform code and the IDE driver
in accordance.Signed-off-by: Sergei Shtylyov

Work around the CPU clock miscalculation on Au1000DA/HA/HB due the
sys_cpupll register being write-only, i.e. actually do what the comment
before cal_r4off() function advertised for years but the code failed at.
This is achieved by just giving user a chance to define the clock
explicitly in the board config. via CONFIG_SOC_AU1000_FREQUENCY option,
defaulting to 396 MHz if the option is not given...The patch is based on the AMD's big unpublished patch, the issue seems to
be an undocumented errata (or feature :-)...Signed-off-by: Sergei Shtylyov

So far flush_cache_range() did't consider the I-cache largely because it
did rarely ever matter to real world code. This was working primarily
because normally code and data are don't share the same pages - with the
exception of MIPS16 code which uses address constants embedded between
the code. The following sequence of events may break the code:o MIPS16 executable being loaded
o dynamic linker relocates the address constants embedded into the code:
o Uses mprotect(2) to make code pages PROT_READ|PROT_WRITE
o Performs the actual relocations by writing to the pages which likely
are COW. Because no PROT_EXEC is set I-cache coherence will not be
considered.
o Uses mprotect(2) to switch code pages back to PROT_READ|PROT_EXEC.
This results in a call to flush_cache_range() which also does not
consider I-caches.
o => executing the page just having been relocated may now result in the
I-cache getting refilled with stale data from memory.Signed-off-by: Ralf Baechle

This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
pairs
- it prepares the VFS for stacking support since it is essential to have a
struct path in every place where the stack can be traversed
- it reduces the overall code size:without patch series:
