return failure if swap is full and there are no free physical pages.
have malloc() use this flag if M_CANFAIL is passed to it.
use M_CANFAIL to allow amap_extend() to fail when memory is scarce.
this should prevent most of the remaining hangs in low-memory situations.
at run time. This simplifies the code and avoids problems with uninitialised
variables, and if it's good enough for pciide(4), it's good enough for me.
Also normalise the prefix for channel-specific messages.
necessary to allow the card to be detected afterwards. In theory, this
shouldn't be necessary, since we don't touch the page latch yet, but I'm not
going to argue.
sort of error message, over and over again, in different files.
Rather than having the same text repeated in multiple .o files,
create a couple of little functions to do the printing, and save a
bundle of space. Also improves readability of code.
- when moving the stylus, the cursor was updated only when the screen was
released
- when moving the stylus for too long, the kernel crashed
This was caused by improper delays in SSP read and write, and by interrupt
hammering while the screen is touched). Both led to the machine handling
interrupts all the time and been unable to schedule the X server, therefore
the lack of cursor refresh.
The problem is fixed by
- masking touchpanel interrupts as soon as we are already handling them
- creating a kernel thread (j720ssp) that takes care of keyboard and
touchpanel I/O, instead of doing it in a softintr.
- reducing delays in j720ssp_readwrite operations from 5ms to 0.1ms.
NB: If the delay in j720ssp_readwrite operation is lowered to 0.1, then
switching on the screen using the power key pushes brightness to maximum.
In order to avoid this, we introduce a wait argument to j720ssp_readwrite,
which specify how many microseconds we have to wait. j720ssp_readwrite is
called with wait = 100 everywhere except in j720lcdparam where it is called
with wait = 500. That way it works.

with humanize_number(3). In reality, the kernel version should be changed
to more closely match the userland version so that there are no prototype
conflicts.
If two signals are sent after each other without the process being run in
userspace between them then the second one will overwrite part of the signal
info stored on the userstack.
Fixed by rewriting and simplifying both the signal delivery code and the
trampoline code. Also bump signal version number to 2.
