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%).

2007-07-24[SPARC64]: Mark most of initial bootup asm as .text.init.ref_okDavid S. Miller1-4/+7
We can't mark the whole thing init because there are dependencies in bootloaders that assume that _start, or whatever the image entry value, is 2 instructions before the "HdrS" signature. In fact, TILO assumes this entry is always at 0x4000, yikes! Also, right after the bootloader info area there are OBP strings and values that get used later in the boot process, and those are not all provably .init yet. Signed-off-by: David S.

2007-07-20[SPARC]: Fix serial console device detection.David S. Miller8-161/+71
The current scheme works on static interpretation of text names, which is wrong. The output-device setting, for example, must be resolved via an alias or similar to a full path name to the console device. Paths also contain an optional set of 'options', which starts with a colon at the end of the path. The option area is used to specify which of two serial ports ('a' or 'b') the path refers to when a device node drives multiple ports. 'a' is assumed if the option specification is missing. This was caught by the UltraSPARC-T1 simulator. The 'output-device' property was set to 'ttya' and we didn't pick upon the fact that this is an OBP alias set to '/virtual-devices/console'. Instead we saw it as the first serial console device, instead of the hypervisor console. The infrastructure is now there to take advantage of this to resolve the console correctly even in multi-head situations in fbcon too. Thanks to Greg Onufer for the bug report.

2007-07-19define new percpu interface for shared dataFenghua Yu1-4/+2
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.
