2012-12-05m68knommu: modify clock code so it can be used by all ColdFire CPU typesGreg Ungerer1-62/+38
The existing clk.c code for ColdFire CPUs has one set of functions to support those CPU types that have selectable clocks (those with a PPMCR register), and a duplicate simpler set for those with static clocks. Modify the clk.c code so there is just one set of support functions. All CPU types now define a list of clocks (in "struct clk"s), so we only need a single set of clock functions.

2012-12-05m68knommu: add clock creation support macro for other ColdFire CPUsGreg Ungerer1-1/+8
The clock support code for ColdFire CPUs currently supports those that have the clock control register PPMCR. Expose the struct clk for all CPU types and add a definition for all other ColdFire CPU types. With this we will be able to define simple clock trees for all ColdFire CPU types, even though they will not be able to be enabled or disabled. They will be able to report the clock rate.

2012-12-05m68k: fix unused variable warning in mempcy.cGreg Ungerer1-1/+2
When compiling for original 68000 or ColdFire targets you will get the following warning when compiling arch/m68k/lib/memcpy.c: CC arch/m68k/lib/memcpy.o arch/m68k/lib/memcpy.c: In function ‘__builtin_memcpy’: arch/m68k/lib/memcpy.c:13:15: warning: unused variable ‘temp1’ This is easily fixed by moving the definition of temp1 into the code block where it is used.

2012-12-05m68knommu: make non-MMU page_to_virt() return a void *Greg Ungerer1-1/+1
The page_to_virt() macro for m68knommu is currently effectively returning an int type. But the equivilent m68k macro returns a void * virtual address. Modify the non-MMU macro to return a void * as well (using the __va macro). This change will remove compiler warnings in common m68k code that use this macro.

2012-12-05m68knommu: merge ColdFire 5249 and 525x definitionsGreg Ungerer5-282/+124
The ColdFire 5249 and 525x family of SoCs are very similar. Most of the internals are the same, and are mapped the same. We can use a single set of peripheral definitions for all of them. So merge the current m5249sim.h and m525xsim.h definitions into a single file. The 5249 is now obsolete, and the 525x parts are current, so I have chosen to move everything into the existing m525xsim.h file. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2012-11-15TTY: call tty_port_destroy in the rest of driversJiri Slaby1-2/+4
After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places.

2012-11-14m68k: move to a single instance of free_initmem()Greg Ungerer4-36/+8
Currently each sub-architecture has its own implementation if init_freemem(). There is two different cases that the various implementations deal with. They either free the init memory, or they don't. We only need a single instance to cover all cases. The non-MMU version did some page alignment twidling, but this is not neccessary. The current linker script enforces page alignment. It also checked for CONFIG_RAMKERNEL, but this also is not necessary, the linker script always keeps the init sections in RAM. The MMU ColdFire version of free_initmem() was empty. There is no reason it can't carry out the freeing of the init memory. So it is now changed and tested to do this. For the other MMU cases the code is the same. For the general Motorola MMU case we free the init memory. For the SUN3 case we do nothing (though I think it could safely free the init memory as well).

2012-11-14m68k: merge MMU and non-MMU versions of mm/init.cGreg Ungerer3-323/+228
Some of the code in the existing mm/init_mm.c and mm/init_no.c files is the same, and if we merge them back to a single file we can save some code duplication. Although the old mem_init() code for non-MMU was a little different than the MMU version, it turns out we can use the same code. So I now we just use the MMU mem_init() code for all. It also means we now get identical console info messages for this code on kernel boot up. So merge the two files back into a single file.

2012-11-13tracing,x86: Add a TSC trace_clockDavid Sharp1-0/+1
In order to promote interoperability between userspace tracers and ftrace, add a trace_clock that reports raw TSC values which will then be recorded in the ring buffer. Userspace tracers that also record TSCs are then on exactly the same time base as the kernel and events can be unambiguously interlaced. Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large timestamp values. v2: Move arch-specific bits out of generic code. v3: Rename "x86-tsc", cleanups v7: Generic arch bits in Kbuild.

2012-11-01sk-filter: Add ability to get socket filter program (v2)Pavel Emelyanov1-0/+1
The SO_ATTACH_FILTER option is set only. I propose to add the get ability by using SO_ATTACH_FILTER in getsockopt. To be less irritating to eyes the SO_GET_FILTER alias to it is declared. This ability is required by checkpoint-restore project to be able to save full state of a socket. There are two issues with getting filter back. First, kernel modifies the sock_filter->code on filter load, thus in order to return the filter element back to user we have to decode it into user-visible constants. Fortunately the modification in question is interconvertible. Second, the BPF_S_ALU_DIV_K code modifies the command argument k to speed up the run-time division by doing kernel_k = reciprocal(user_k). Bad news is that different user_k may result in same kernel_k, so we can't get the original user_k back. Good news is that we don't have to do it. What we need to is calculate a user2_k so, that reciprocal(user2_k) == reciprocal(user_k) == kernel_k i.e. if it's re-loaded back the compiled again value will be exactly the same as it was. That said, the user2_k can be calculated like this user2_k = reciprocal(kernel_k) with an exception, that if kernel_k == 0, then user2_k == 1. The optlen argument is treated like this -- when zero, kernel returns the amount of sock_fprog elements in filter, otherwise it should be large enough for the sock_fprog array. changes since v1: * Declared SO_GET_FILTER in all arch headers * Added decode of vlan-tag codes Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.
