      ARC: [nsimosci] Unbork console · 61fb4bfc
      由 Vineet Gupta 提交于 
      Despite the switch to right UART driver (prev patch), serial console
still doesn't work due to missing CONFIG_SERIAL_OF_PLATFORM

Also fix the default cmdline in DT to not refer to out-of-tree
ARC framebuffer driver for console.

      ARC: [nsimosci] Change .dts to use generic 8250 UART · 6eda477b
      由 Mischa Jonker 提交于 
      The Synopsys APB DW UART has a couple of special features that are not
in the System C model. In 3.8, the 8250_dw driver didn't really use these
features, but from 3.9 onwards, the 8250_dw driver has become incompatible
with our model.

      locking/mcs: Allow architecture specific asm files to be used for contended case · ddf1d169
      由 Tim Chen 提交于 
      This patch allows each architecture to add its specific assembly optimized
arch_mcs_spin_lock_contended and arch_mcs_spinlock_uncontended for
MCS lock and unlock functions.

      locking/mcs: Order the header files in Kbuild of each architecture in alphabetical order · b119fa61

      We perform a clean up of the Kbuid files in each architecture.
We order the files in each Kbuild in alphabetical order
by running the below script.

                i = 3;
                do {
                        for (; i <= NF; i++) {
                                if ($i == "\\") {
                                        getline;
                                        i = 1;
                                        continue;
                                }

      ARC: Add guard macro to uapi/asm/unistd.h · 97bc386f
      由 Vineet Gupta 提交于 
      Chen originally proposed this as "right thing to do" however I
actually ran into this when building perf tools. Some of the utils
include unistd.h as well as linux/unistd.h. Since -I includes kernel
headers too, we end up including the ARC unistd.h twice, leading to
redefinition nwarnings.
