Subject: [PATCH 1/3] Get rid of UFS_WAPBL_BEGIN1/END1

ufs makeinode no longer releases dvp, so incrementing the
usecount for wapbl is unnecessary.

Subject: [PATCH 1/1] Simplify ufs_wapbl_end2

Similar to ufs_wapbl_begin2, this function is rarely called with vnodes,
and when it does - it's only with one parameter.

The only thing we do with the vnode when it's rarely used, is decrement
the usecount. do this explicitly instead.

Subject: [PATCH 1/1] Simplify ufs_wapbl_begin2

The purpose of the vnode parameters in this function is to increase
usecount (only).
This is only used by ufs_symlink (where it is called UFS_WAPBL_BEGIN1),
otherwise it is called with NULL, NULL as vnodes (UFS_WAPBL_BEGIN).

you've forgotten to apply this.
I suspected it is because you only have the ones that got all broken up.
this appears to apply well.

enable nouveau in i386 ALL config.
it's already enabled in GENERIC.

small fixes:
nouveaufbbus -> nouveaufbbus? to fix build failure (same as GENERIC)
remove option NV_DEBUG because it is redefined in the code. (doesn't exist in amd64 ALL, either)
