e6634fbd0c 6c: conserve registers for floating point operations
for floating point operations, reuse the return register
on the right hand side if it has higher complex number
than the left hand side to conserve registers.

this makes the following code compile, that was previously
run out of floating point register:

float
f(float r[15])
{
	return (r[0] + (r[1] * (r[2] + r[3] * (r[4] + r[5] * (r[6] + r[7] * (r[8] + r[9] * (r[10] + r[11] * (r[12] + r[13] * r[14]))))))));
}

the downside is that this produces extra move operations.

380adf8b48 aux/getflags: support named flags
When using aux/getflags, it produces unnecessarily obscure
names for the flags. This allows the caller of aux/getflags

94bd7700aa rc: fix code serialization for PIPEFD (thanks BurnZeZ)
BurnZeZ reported this the other day. It seems like if we have
a pipeline that looks like:

	fn foo{cat < <{echo hi}}

then the '<' will get merged in /env/'fn#foo'. This change
fixes pcmd to add a space. It looks to me like this is the
only token that can get merged this way by pcmd.

the maximum number of ip stacks is a implementation detail
of devip. it is 128 currently, instead of 16 as suggested

2d1dac07f7 triple-click to select non-whitespace segment
The previous patch to plumb non-whitespace segments was
confusing due to lack of visual feedback. This removes
the empty selecton plumb behavior, and instead makes
triple clicking work to get a plumbable selection.

(we are the default gateway). ignore such entries.

ca9d65e40b cc: remove mysbrk(), exponentially increase gethunk() allocation delta
mysbrk() was only used in gethunk() and should not be
called by anyone, so dont export the symbol.

simplify gethunk() using brk().

double allocation size on each call until we reach
1000*NHUNK.

use signed long for nhunk as alignment rountin might
make it negative and handle that case.

1b8a569417 cc, ?[acl]: fix gethunk() and move common memory allocator code to cc/compat
for gethunk() to work, all allocators have to use it,
including allocations done by libc thru malloc(),
so the fake allocation functions are mandatory for
everyone.

to avoid duplication the code is moved to cc/compat
and prototypes provided in new cc/compat.h header.

9d46360c9d backout the gethunk() again, as that breaks the assemblers
the assemblers share gethunk() cc/macbody but are compiled
without compat.c, so calls such as getenv() trigger malloc()
which does its own sbrk() calls, breaking the continuity
of the hunk.

so this change needs another revision. until then, this is
backed out.

1d3644a168 cc, ?l: fix gethunk() to actually grow allocation
the compilers and linkers use ther own memory allocator.
free memory is between hunk and hunk+nhunk. allocation
works by checking if nhunk is bigger or equal to the
amount needed, and if not, repeatedly call gethunk()
until there is. after that, the allocated amount is added
from hunk and subtracted from nhunk by the user.

the problem was when the needed amount was bigger than
the default NHUNK size gethunk() allocates per call.
gethunk() would not actually grow nhunk, but instead
just set hunk and nhunk variables to the last allocated
block. this resulted in a infinite loop of calls to
gethunk() until sbrk() would hit the maximum size for
the BSS segment.

this change makes gethunk() actually grow the hunk space,
increasing nhunk, and only updating hunk when nhunk was
previously zero. we assume that mysbrk() retuns increasing
addresses and that the space between the previous hunk+nhunk
and the new block base returned by mysbrk() is usable.

a39cc60c52 cc: backout gethunk() change
the real problem is that gethunk() does not grow the allocation
but just allocates a new hunk, so repeated calls to gethunk()
wont make nhunk grow to satisfy the allocation.

this will be fixed in a upcoming commit.

1fe3143e4c kernel: cleanup the software mouse cursor mess
The swcursor used a 32x32 image for saving/restoring
screen contents for no reason.

Add a doflush argument to swcursorhide(), so that
disabling software cursor with a double buffered
softscreen is properly hidden. The doflush parameter
should be set to 0 in all other cases as swcursordraw()
will flushes both (current and previours) locations.

Make sure swcursorinit() and swcursorhide() clear the
visibility flag, even when gscreen is nil.

Remove the cursor locking and just do everything within
the drawlock. All cursor functions such as curson(),
cursoff() and setcursor() will be called drawlock
locked. This also means &cursor can be read.

Fix devmouse cursor reads and writes. We now have the
global cursor variable that is only modified under
the drawlock. So copy under drawlock.

Move the pc software cursor implementation into vgasoft
driver, so screen.c does not need to handle it as
a special case.

Remove unused functions such as drawhasclients().

5f1b70f437 pc, pc64: new memory map code
This replaces the memory map code for both pc and pc64
kernels with a unified implementation using the new
portable memory map code.

The main motivation is to be robust against broken
e820 memory maps by the bios and delay the Conf.mem[]
allocation after archinit(), so mp and acpi tables
can be reserved and excluded from user memory.

There are a few changes:

new memreserve() function has been added for archinit()
to reserve bios and acpi tables.

upareserve() has been replaced by upaalloc(), which now
has an address argument.

umbrwmalloc() and umbmalloc() have been replaced by
umballoc().

both upaalloc() and umballoc() return physical addresses
or -1 on error. the physical address -1 is now used as
a sentinel value instead of 0 when dealing with physical
addresses.

archmp and archacpi now always use vmap() to access
the bios tables and reserve the ranges. more overflow
checks have been added.

ramscan() has been rewritten using vmap().

to handle the population of kernel memory, pc and pc64
now have pmap() and punmap() functions to do permanent
mappings.

d3512f60df ip/dhcp6d: work arround non-ethernet based client duid
in ndb, we use the ethernet mac to identify the client.
in dhcpv6, there is just a uniqueue device id that
might even be generated randomly. to find the ethernet
address of a client, check the duid type and only use
it when the dudid is of type 1 (link layer) or 3 (link
layer address + time) and the link layer address type
is 1 (ethernet). otherwise, assume the source ip is
a link local address and extract it from that.

this hack works for thinkpad t495, which uses random
uuid based client duid.
