In sun4c_init_clean_mmu(), aligning 'kernel_end' using
SUN4C_REAL_PGDIR_ALIGN() is unnecessary since the caller
does this already.In sun4c_paging_init(), 4 page sizes of "fluff" were added
to the address of &end. This was necessary a long time ago
when sparc32 would allocate some early data structures
by carving out memory chunks after &end but that no longer
occurs.Signed-off-by: Mark Fortescue

This deals with a sun4c issue caused by commit b6a2fea39318e43fee84fa7b0b90d68bed92d2ba:
mm: variable length argument support.The new way the code works means that sun4c_update_mmu_cache gets
called before a context has been selected, which results in invalid
operation of the underling mm code.Simply ignoring update requests when there is no valid context solves
the problem.Signed-off-by Mark Fortescue

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%).Cross-compile tested without regressions on my two usual configs and (sigh):

Sparc optimized memset (arch/sparc/lib/memset.S) does not fill last
byte of the memory area, if area size is less than 8 bytes and start
address is not word (4-bytes) aligned.Here is code chunk where bug located:
/* %o0 - memory address, %o1 - size, %g3 - value */
8:
add %o0, 1, %o0
subcc %o1, 1, %o1
bne,a 8b
stb %g3, [%o0 - 1]This code should write byte every loop iteration, but last time delay
instruction stb is not executed because branch instruction sets
"annul" bit.Patch replaces bne,a by bne instruction.

__ndelay and __udelay have not been delayung >= specified time.
The problem with __ndelay has been tacked down to the rounding of the
multiplier constant. By changing this, delays > app 18us are correctly
calculated.
The problem with __udelay has also been tracked down to rounding issues.
Changing the multiplier constant (to match that used in sparc64) corrects
for large delays and adding in a rounding constant corrects for trunctaion
errors in the claculations.
Many short delays will return without looping. This is not an error as there
is the fixed delay of doing all the maths to calculate the loop count.Signed-off-by: Mark Fortescue

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.

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.Signed-off-by: Fenghua Yu
