A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added. |

More suncc fixes.
- remove more empty declarations
- add options to turn errors on empty structs into warnings and options to
silence these warnings |

More suncc fixes.
- Removed extra semicolons after function declaration.
- Sun Studio recognizes only C99 __func__ and no gcc-specific __FUNCTION__.
In this case, a simple -D option can fix the problem. |

Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur. |

/trunk/kernel/arch/ia32/src/smp/ |
On SMP amd64 and ia32 systems, release the irq->lock
before calling clock() from the interrupt handler.
This is important for maintaining kernel preemption
since no preemption can take place while a spinlock
is held. |

Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.
Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary. |

The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.
Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache. |
