Extremly low values are of dubious usefulness anyway but in this case
they actually were killing Qemu which simply wasn't able to complete
mips_next_event() within 0x30 100MHz cycles even on fast hosts.

Turns out b868868ae0f7272228c95cc760338ffe35bb739d wasn't quite right.
When called for a page that isn't marked dirty it would artificially
create an alias instead of doing the obvious thing and access the page
via KSEG0.
The same issue also exists in copy_to_user_page and copy_from_user_page
which was causing the machine to die under rare circumstances for example
when running ps if the BUG_ON() assertion added by the earlier fix was
getting triggered.

improve performance of sys_time(). sys_time() returns time in seconds,
but it does so by calling do_gettimeofday() and then returning the
tv_sec portion of the GTOD time. But the data structure "xtime", which
is updated by every timer/scheduler tick, already offers HZ granularity
time.

There is a test in tgafb_mono_imageblit() for a colour image with a fall-back
to cfb_imageblit(). The test is not necessary as the only caller, which is
tgafb_imageblit(), checks it too and only invokes this function for monochrome
images. It looks like a left-over from before some changes to
tgafb_imageblit().

The pixel mask calculation in tgafb_mono_imageblit() uses a variable
left-shift on a 32-bit data type by up to 32. Shifting by the width of a data
type or more produces an unpredictable result according to the C standard.
Rather than widening the data type this fix makes sure the count is between 0
and 31. The reason is not to penalise 32-bit platforms with operation on a
"long long" type for a marginal case that is meant not to happen (blitting an
image of a zero width).
The reason it has escaped for so long is the Alpha, being purely 64-bit, :-)
does not mask the shift out to 32 bits. This is a valid implementation --
producing the correct result certainly falls within "unpredictable behaviour".
It does trigger on MIPS though and it is the recent merge of the TC support
which only enabled the driver for use on anything other than the Alpha. For
MIPS when the width is 32 the mask ends up being 0 rather than 0xffffffff as
it should be and the frame buffer is not updated.

As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular
cursor can still be seen blinking in the upper left part of the screen. It is
fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE,
KD_TEXT) call done by something in userspace, perhaps by X itself, while the
tty is still in graphics mode. And when the tty is in KD_TEXT mode, the
cursor timer is restarted.
Although this is a userspace problem, we can work around it by delaying the
restart of the cursor timer until an fbcon_switch() is called. In other
words, the cursor timer will not be restarted even if a KD_TEXT mode switch is
requested.

This correct case, when source and destination X coordinates difference is n
multiple of pixels in byte. This is probably rare case, but this case should
supported for completeness.
Reorganization of FB_READL and FB_WRITEL calls results in code size decrease
for normal build without swapping support and size with support enabled is
reasonable too.

ps3fb: Enhance horizontal panning on firmware 1.90 and up:
- On firmware 1.90 and up, L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT supports copying
rectangles from XDR to DDR memory with different source and destination
line lengths. Hence larger horizontal virtual resolutions can be supported
(up to 16368 pixels).
- As the actual frame buffer memory layout no longer matches the entries in
ps3fb_res[], create fake struct ps3fb_ioctl_res data for the
PS3FB_IOCTL_SCREENINFO ioctl, so user space applications that depend on it
keep on working.

ps3fb: Add virtual screen and panning support:
- The vertical virtual screen size is limited by the amount of memory
reserved for ps3fb,
- The horizontal virtual screen size is limited to the fullscreen width,
- Advertise that we support panning, so fbcon will use it if the virtual
screen is enabled.
Enabling a virtual screen (using `fbset -vyres nnn') can speed up text
console scrolling by a factor of 10-15, depending on the video mode.

ps3fb: In the case of non-fullscreen video modes, there was a partial overlap
of the GPU command buffer and the frame buffer. Fix and cleanup various issues
with overlap and alignment:
- Move the GPU command buffer from the beginning to the end of video memory
- Exclude the GPU command buffer from the actual frame buffer memory
- Align the start of the virtual frame buffer to PAGE_SIZE instead of to 64
KiB, and don't waste memory if it's already aligned (for fullscreen modes)
- Take into account the alignment when checking memory requirements and
maximum number of frames
- Make sure fb_fix_screeninfo.smem_start always points to the virtual frame
buffer start, so we don't have to compensate for that in ps3fb_mmap()

The i.MX frame-buffer read operation should be faster for all configurations
then drawing each individual character again in response to scroll events.
The nonstandard fields allows to configure frame-buffer special options flags
for different display configurations by board specific initialization code.
One of such specific options is reversed order of pixels in each individual
byte. i.MX frame-buffer seems to be designed for big-endian use first. The
byte order is correctly configured for little-endian ordering, but if 1, 2 or
4 bits per pixel are used, pixels ordering is incompatible to Linux generic
frame-buffer drawing functions.
The patch "Allow generic BitBLT functions to work with swapped pixel order in
bytes" introduces required functionality into FBDEV core. The pixels ordering
selection has to be enabled at compile time CONFIG_FB_CFB_REV_PIXELS_IN_BYTE
and for each display configuration which requires it by flag
FB_NONSTD_REV_PIX_IN_B in "nonstd" field of info structure.
This patch provides way for board specific code to select this option.
