Hi,
latest stable 4.14.63-rt40 fails with CONFIG_HYPERV:
drivers/hv/vmbus_drv.c: In function ‘vmbus_isr’:
drivers/hv/vmbus_drv.c:969:25: error: implicit declaration of function
‘get_irq_regs’; did you mean ‘get_mm_rss’?
[-Werror=implicit-function-declaration]
struct pt_regs *regs = get_irq_regs();
^~~~~~~~~~~~
get_mm_rss
drivers/hv/vmbus_drv.c:969:25: warning: initialization of ‘struct
pt_regs *’ from ‘int’ makes pointer from integer without a cast
[-Wint-conversion]
Thomas' 5bef95248a270f68a1e448337b1d4c927cf8b0b2 in stable-rt ("random:
Make it work on rt") seems to break it. 4.14.59-rt37 compiles fine, so I
guess the include chain somehow changed upstream.
Simple fix below, include irq_regs.h.
