If GCC >= 4.9 and Binutils >=2.25, we use -march=loongson3a, otherwise we use -march=mips64r2, this can slightly improve performance. Besides, arch/mips/loongson64/Platform is a better location rather than arch/ mips/Makefile. Signed-off-by: Huacai Chen <chenhc@lemote.com> Cc: Aurelien Jarno <aurelien@aurel32.net> Cc: Steven J.

Add an `ieee754=' kernel parameter to control IEEE Std 754 conformance mode. Use separate flags copied from the respective CPU feature flags, and adjusted according to the conformance mode selected, to make binaries requesting individual NaN encoding modes accepted or rejected as needed. Update the initial setting for FCSR and, in the full FPU emulation mode, its read-only mask accordingly. Accept the mode selection requested for legacy processors as well. As with the EF_MIPS_NAN2008 ELF file header flag adjust both ABS2008 and NAN2008 bits at the same time, to match the choice made for hardware currently implemented. Signed-off-by: Maciej W.

Determine the presence of and the amount of control available over IEEE Std 754-2008 features. In the case of a hardware FPU being used examine the FIR register for the presence of the HAS2008 bit and then the FCSR register for the writability of the ABS2008 and NAN2008 bits and the hardwired state of each of these bits if read-only. Update the initial FCSR contents used for threads and the FCSR writability mask accordingly. For full FPU emulation and MIPS32 or MIPS64 processors make the FCSR ABS2008 and NAN2008 bits writable.

Handle the EF_MIPS_NAN2008 ELF file header flag and refuse execution where there is no support in the FPU for the NaN encoding mode requested by a binary invoked. Ensure that the setting of the bit in the binary matches one in any intepreter used. Set the thread's initial FCSR contents according to the value of the EF_MIPS_NAN2008. Set the values of the FCSR ABS2008 and NAN2008 bits both to the same value if possible, to take the approach taken with existing FPU hardware into account. As of now all implementations have both bits hardwired to the same value, that is both are fixed at 0 or both are fixed at 1, even though the architecture allows for implementations where the amount of control implemented with each of these two individual bits is independent of each other.

Implement IEEE Std 754-2008 NaN encoding wired to the state of the FCSR.NAN2008 bit. Make the interpretation of the quiet bit in NaN data as follows: * in the legacy mode originally defined by the MIPS architecture the value of 1 denotes an sNaN whereas the value of 0 denotes a qNaN, * in the 2008 mode introduced with revision 5 of the MIPS architecture the value of 0 denotes an sNaN whereas the value of 1 denotes a qNaN, following the definition of the preferred NaN encoding introduced with IEEE Std 754-2008. In the 2008 mode, following the requirement of the said standard, quiet an sNaN where needed by setting the quiet bit to 1 and leaving all the NaN payload bits unchanged. Update format conversion operations according to the rules set by IEEE Std 754-2008 and the MIPS architecture. Specifically: * propagate NaN payload bits through conversions between floating-point formats such that as much information as possible is preserved and specifically a conversion from a narrower format to a wider format and then back to the original format does not change a qNaN payload in any way, * conversions from a floating-point to an integer format where the source is a NaN, infinity or a value that would convert to an integer outside the range of the result format produce, under the default exception handling, the respective values defined by the MIPS architecture. In full FPU emulation set the FIR.HAS2008 bit to 1, however do not make any further FCSR bits writable. Signed-off-by: Maciej W.

In the non-arithmetic mode the sign bit is altered according to the operation requested regardless of the datum encoded in the input operand, no other bits are changed, the resulting bit pattern is written to the output operand and no exception is ever signalled.

The "a" version of the MT7620 has single port PCIE bus. The driver is straightforward without any special magic required. The driver works on MT7620 and MT7628. There are a few magic values that get written to the pcie phy and a register of which we only know the name. I marked these places as vodoo in the comments above the code.

BCM47XX platform has specific PCI setup because all buses share the same domain. It's different e.g. on ARM ARCH_BCM_5301X where each PCI bus gets its own domain (they are handled by iProc PCIe controller driver). As we want to make SPROM driver more generic, let's add an exception for BCM47xx. It was tested on BCM4706 (MIPS) and BCM4708A0 (ARM).

Add device tree nodes for the NEMC and BCH to the JZ4780 device tree, and make use of them in the Ci20 device tree to add a node for the board's NAND. Note that since the pinctrl driver is not yet upstream, this includes neither pin configuration nor busy/write-protect GPIO pins for the NAND. Use of the NAND relies on the boot loader to have left the pins configured in a usable state, which should be the case when booted from the NAND.

In sctp_close, sctp_make_abort_user may return NULL because of memory allocation failure. If this happens, it will bypass any state change and never free the assoc. The assoc has no chance to be freed and it will be kept in memory with the state it had even after the socket is closed by sctp_close(). So if sctp_make_abort_user fails to allocate memory, we should abort the asoc via sctp_primitive_ABORT as well. Just like the annotation in sctp_sf_cookie_wait_prm_abort and sctp_sf_do_9_1_prm_abort said, "Even if we can't send the ABORT due to low memory delete the TCB. This is a departure from our typical NOMEM handling". But then the chunk is NULL (low memory) and the SCTP_CMD_REPLY cmd would dereference the chunk pointer, and system crash. So we should add SCTP_CMD_REPLY cmd only when the chunk is not NULL, just like other places where it adds SCTP_CMD_REPLY cmd.
