2007-08-27[MIPS] Do not discard extra debugging sections.Daniel Jacobowitz1-3/+4
Leaving these sections is useful to some tools that look at the image, and none of them are loaded into memory. The .mdebug.abi64 section, in particular, lets GDB recognize vmlinux.32 as an N64 program instead of guessing that it is O32.

2007-07-29Remove fs.h from mm.hAlexey Dobriyan2-0/+2
Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it. As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files rebuilt down to 3444 (-12.3%).

2007-07-19define new percpu interface for shared dataFenghua Yu1-4/+1
per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

2007-07-12[MIPS] SMTC: Interrupt mask backstop hackKevin D. Kissell2-0/+4
To support multiple TC microthreads acting as "CPUs" within a VPE, VPE-wide interrupt mask bits must be specially manipulated during interrupt handling. To support legacy drivers and interrupt controller management code, SMTC has a "backstop" to track and if necessary restore the interrupt mask. This has some performance impact on interrupt service overhead. Disable it only if you know what you are doing. Signed-off-by: Ralf Baechle <[email protected]>

Currently a number of unaligned instructions is counted but not used. Add /debug/mips/unaligned_instructions file to show the value. And add /debug/mips/unaligned_action to control behavior upon an unaligned access.
