The allocation of all of our components should be done in slave alloc. Currently it's rather fancifully refcounted in the queuecommand callback. This patch moves allocation and destroy to their correct places in slave_alloc/slave_destory. Now we can guarantee that everywhere a device is requested, it's actually been allocated, so don't check for this anymore. Additionally, the per device busy timer was the only source of potential use after free. It's been deleted because Linux does the correct thing with busy returns, so there's no need to implement a separate timer in the driver. Finally, implement code that forces all the device parameters to zero (i.e. async and narrow) in the slave alloc, inform the spi class of the bios recorded maximums and wait until slave configure before trying anything more adventurous.

This should finish the spurious queue removal from aic7xxx (there are other queues that are probably unnecessary, but at least the major and obviously unnecessary ones are done with). Signed-off-by: -

This was rendered obsolete by the busyq removal; remove some of the last remnants of its presence. Signed-off-by: -

There's not much sense in sharing code anymore now that aic7xxx uses various transport class facilities. Signed-off-by: -

The aic7xxx driver has two spurious queues in it's linux glue code: the busyq which queues incoming commands to the driver and the completeq which queues finished commands before sending them back to the mid-layer This patch just removes the busyq and makes the aic finally return the correct status to get the mid-layer to manage its queueing, so a command is either committed to the sequencer or returned to the midlayer for requeue.

This is similar to the previous sym2 problem. For Domain Validation to work we can't allow any period setting to turn wide on if it was previously off. Signed-off-by: -
James Bottomley authored
There's a basic need not to have parameters go under or over certain values when doing domain validation. The basic ones are max_offset, max_width and min_period This patch makes the transport class take and enforce these three limits. Currently they can be set by the user, although they could obviously be read from the HBA's on-board NVRAM area during slave_configure (if it has one). Signed-off-by:

This fixes some x86_64 bugs - - maybe_map returns -1 on error instead of 0, which is interpreted as physical address 0 - removed an include of ipc.h, which isn't needed - fixed the calculation of signal frame location - the signal delivery code is now immune to the stack expansion check - added a missing include Signed-off-by:

tt-mode closes switch_pipes in exit_thread_tt and kills processes in switch_to_tt, if the exit_state is EXIT_DEAD or EXIT_ZOMBIE. In very rare cases the exiting process can be scheduled out after having set exit_state and closed switch_pipes (from release_task it calls proc_pid_flush, which might sleep). If this process is to be restarted, UML failes in switch_to_tt with: write of switch_pipe failed, err = 9 We fix this by closing switch_pipes not in exit_thread_tt, but later in release_thread_tt. Additionally, we set switch_pipe[0] = 0 after closing. switch_to_tt must not kill "from" process depending on its exit_state, but must kill it after release_thread was processed only, so it examines switch_pipe[0] for its decision.

Only x86 and x86_64 use arch_align_stack(), all other subarches have: #define arch_align_stack(x) (x) So, if this definition is found, UML's own arch_align_stack() should be skipped. Signed-off-by:

s390 tt-mode needs to save not only syscall number, but an further register also. Signed-off-by:
-
Bodo Stroesser authored
s390 needs to change some parts of arch/um/kernel/ptrace.c. Thus, the code regarding PEEKUSER and POKEUSER are shifted to arch/um/sys-<subarch>/ptrace.c. Also s390 debug registers need to be updated, when singlestepping is switched on / off. Thus, setting/resetting of singlestepping is centralized in the new function set_singlestep(), which also inserts the macro SUBARCH_SET_SINGLESTEP(mode), if defined. Finally, s390 has the "ieee_instruction_pointer" in its registers, which also is allowed to be read via ptrace( PTRACE_PEEKUSER, getpid(), PT_IEEE_IP, 0); To implement this feature, sys_ptrace inserts the macro SUBARCH_PTRACE_SPECIAL, if defined.

Remove the __deprecated from verify_area_skas and verify_area_tt. Since verify_area is itself marked __deprecated, and it is the only caller of these, then they don't need to be marked. Marking them only makes the build noisier. Signed-off-by:

This patch adds a VIDIOC_G_FREQUENCY command to tuner-core.c and sets lowest and highest tunable frequencies in v4l2_tuner structure returned by VIDIOC_G_TUNER command. Signed-off-by:

Jiri Benc authored
In VIDIOC_S_FREQUENCY command in tuner-core.c, t->freq is set to a new value before calling set_freq(). This is not necessary, as set_freq() sets t->freq itself. Moreover, it causes problems with Philips tuners, as they need to take into consideration difference between previous and new frequency. Signed-off-by:

This change from March 3rd causes the partition parsing code to ignore partitions which have a signature byte of zero. Turns out that more people have such partitions than we expected, and their device numbering is coming up wrong in post-2.6.11 kernels. So revert the change while we think about the problem a bit more. Cc: Andries Brouwer <Andries.Brouwer@cwi.nl> Signed-off-by:

There's a slight bug in the routines in that if the period requires dt, then the routine will unconditionally set it. DT may only be set if Wide is also set, so this turns back on the wide bit. For domain validation to work correctly, we need to observe the wide bit absolutely. Acked by: Matthew Wilcox <willy@debian.org> Signed-off-by: -

The defines in bootinfo.h are not used, so the include can be removed. According to Ben, birecs are not used on ppc64: on ppc64, we made the decision of enforcing the presence of an OF device-tree and either an OF-like client interface or a kexec like flattened tree. so if your bootloader want to say things to the kernel, it can do so by adding properties to the device-tree compile-tested with defconfig Signed-off-by:

The code in reloc_offset is actually subtracting the address in the link register from the address calculated by the linker.
