linux-next: build failure after merge of the final tree (tty tree related)

[Stephen Rothwell]

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/tty/ehv_bytechan.c: In function 'udbg_init_ehv_bc':
drivers/tty/ehv_bytechan.c:230:18: error: 'MSR_GS' undeclared (first use in this function)
drivers/tty/ehv_bytechan.c: In function 'ehv_bc_console_write':
drivers/tty/ehv_bytechan.c:289:24: warning: cast from pointer to integer of different size
drivers/tty/ehv_bytechan.c: In function 'ehv_bc_console_init':
drivers/tty/ehv_bytechan.c:355:24: warning: cast to pointer from integer of different size

Caused by commit dcd83aaff1c8 ("tty/powerpc: introduce the ePAPR embedded
hypervisor byte channel driver").

MSR_GS is defined in arch/powerpc/include/asm/reg_booke.h which is
included by arch/powerpc/include/asm/reg.h but only when defined
(CONFIG_BOOKE) || defined(CONFIG_40x).

I have reverted that commit for today.
