The add_bounce_page() can be called from _bus_dmamap_load_phys().
Client virtual address is zero (not valid) in that case. So, client
physical address must be used to get an offset when
BUS_DMA_KEEP_PG_OFFSET flag is set. Note that client physical address
is always valid.

odone() in g_io_schedule_up() is wrapped by THREAD_NO_SLEEPING()
and THREAD_SLEEPING_OK(), IMHO, there is something missing in code as

Hi,
could somebody help me, please, with too many following warnings:
sys/buf_ring.h:189:33: warning: variable 'cons_next_next' set but not used
As the warning is produced by header which is included a lot, the important

Hi,
the access to sysmaps_pcpu[] should be atomic with respect to
thread migration. Otherwise, a sysmaps for one CPU can be stolen by
another CPU and the purpose of per CPU sysmaps is broken. A patch is
enclosed.

I'm just syncing my ARM pmap code (base on i386 one) with current

Hi,
I found out that while the running excecutables and a dynamic linker
are protected against writing (ETXTBSY), the loaded shared libraries
are not protected. The libraries are mapped by mmap() in dynamic
linker (rtld) and there is no way how to set VV_TEXT flag on the

I found out that on a few places pmap_qenter() is called on pages
which are not wired. For example, in the following functions, when
vm_pager_get_pages() is called, the pages are not wired:
exec_map_first_page() in sys/kern/kern_exec.c

Hallo,
a size of 'struct vpglocks' is padded to CACHE_LINE_SIZE size in
'sys/vm/vm_page.h'
header file. I work on a 'coldfire' port where CACHE_LINE_SIZE is 16 bytes and
sizeof(struct mtx) is 20 bytes thus size alignment doesn't work.
I solved it somehow, but I like to learn how to solve it i
