David Karoly f61fb770f0 kernel/arm: don't set Accessed Flag when initially mapping a page 
Pages should not be marked as accessed when initially mapping them.

However, there's a short interval during kernel startup when new pages
are mapped but the fault handler is not installed yet.

Therefore, we set Accessed Flag to 1 in early_map.
Once the kernel initialization has progressed enough, we start mapping
new pages with Accessed Flag set to 0.

The chicken and egg problem of initially mapping the vector page is
tackled by preallocating the vector page in the boot loader.
