4c63796838 ia32_pci: rename N_PIC_IRQS to NUM_STD_IRQS
That number is not representing the number of PIC IRQs, but rather the
number of "standard", fixed-number IRQs on a (legacy) x86 PC platform.

c963861d47 Remove PIC code, but not PIC disabling code
Removes the non-PIC disabling PIC code as the PIC is not a supported interrupt
controller.  The PIC disabling code remains as it is needed to prevent the
generation of spurious interrupts from the PIC (see CONFIG_SHUTOFF_PIC).

b643468280 IOAPIC defaults to y when LOAPIC is enabled
For as long as the IOAPIC and LOAPIC code is coupled (as it currently is),
enabling LOAPIC must select IOAPIC to be enabled as well.  If future commits
separate the two, then the "select IOAPIC" can be dropped.

Note that the prj.mdef are different for both tests, since

0abe07a0cd microkernel: introduce support for private memory maps
This enable defining memory maps in source code in addition to
defining in MDEF files. This introduces the macro
DEFINE_MEM_MAP(mem_map_name, ...). The memory maps created this
way are the same, in functionality, as those defined in MDEF
files. They can be manipulated by the standard microkernel
memory map APIs.

Define the memory map using:

  DEFINE_MEM_MAP(mem_map1, blocks, block_size);

and "mem_map1" can be used, for example:

  task_mem_map_alloc(mem_map1, ...);

or,

  task_mem_map_free(mem_map1, ...);

etc.

To use the memory map defined in another source file, simply add:

extern const kmemory_map_t mem_map1;

to the desired C or header file.

To support private memory map objects (aka, defining them within

are not only processed through sysgen, but also those defined

This is done by creating a new section in binary, and all memory
map pointers go into this section. By doing this, the list
can still be manipulated as an array.

This is done by creating a new section in binary, and all pipe

putting the pointers to pipe, instead of the pipe objects
themselves, is that some compiler/linker may pad the large pipe
struct. For example, compiling under gcc and march=i686 pads
the struct to 32-byte alignment (march=atom to 64-byte alignment).
This causes issue with sizeof() and pointer arithmetic because
they have no idea about the padding. So use pointers here to
prevent padding.

2285976f03 microkernel: redefine pipe object identifier type
The opaque pipe object id type is now a pointer to
the associated pipe structure, rather than an index
into the microkernel's array of pipe structures.

This change is a pre-requisite to support for private
pipes, which are defined in source code.

This also moves the required struct into more visible
headers such that private pipes can be declared.
Renaming the struct is also being done to conform to
naming convention for private kernel objects.
Since a couple structs have to be moved anyway, so
do the moving and renaming here too (contrary to what
have been done in the past, with separated patches).
