(and rename it to sysvbfs_file_setsize()) because it's actually
part of vnode ops and bfs.c is also pulled by standalone bootloaders
which don't want vnode header mess.
fs/puffs/t_fuzz:mountfuzz7, fs/puffs/t_fuzz:mountfuzz8,
and fs/zfs/t_zpool:create tests pass again. Patch from
manu, discussed on tech-kern and committed at his request.
excludes the 'jmp alltraps'.
Use the _NJ versions for trap entries with non-standard code.
Move all the KDTRACE_HOOKS code into a single block inside the
IDTVEC(trap03) code. This removes a mis-predicted from every
trap when KDTRACE_HOOKS are enabled.
Add a few blank lines, need some comments as well :-)
No functional changes intended.
Merge the XEN/non-XEN versions of INTRFASTEXIT and
INTR_RECURSE_HWFRAME by using extra defines.
Split INTRENTRY so that code can insert extra instructions
inside user/kernel conditional.
for ports which don't bother to have unnecessary bus_dma(9) implementation
to appease MI driver modules that require bus_dma_tag_t.
For amiga, move <m68k/bus_dma.h> inclusion from <machine/pci_machdep.h>
to <machine/bus.h> since amiga will want actual bus_dma(9) in future
for PCI devices.
Fixes builds on sys/modules/if_axe etc on ancient ports.
"Sounds good" from martin@ on port-m68k@.
Use this opportunity to skip calculating the VA of the page. Let the CPU
deal with the invalidation itself through invlpg + destination address to
avoid converting between canonical/non canonical forms.
the TLB and the CPU will not notice the access right change.
This results in write protection faults in supervisor mode when patching
kernel code through ddb(4) (originally mapped as read only).
Bug reported by David Laight on port-amd64@ (thanks!), patch and test by
me.
i386 is unaffected as PG_LGFRAME does not mask the sign bits. For the
sake of correctness, use VA_SIGN_NEG(...) anyway.
XXX this is the patch that will be pulled-up to -5 and -6.
calls as these operations are synchronously flushed under Xen; they should
not be cached.
XXX the code can be shared between i386 and amd64, but I will merge
them once I figure out why db_write_text() can cause page faults for
certain CPUs in long mode (code looks correct, but single stepping or
adding debug printf's makes the bug magically disappear... sigh)
Bug reported by David Laight on port-amd64@ when attempting to set
breakpoints through ddb(4).
