[PATCH 5.1 043/121] MIPS: mark ginvt() as __always_inline

[PATCH 5.1 043/121] MIPS: mark ginvt() as __always_inline

[Greg Kroah-Hartman]

[ Upstream commit 6074c33c6b2eabc70867ef76d57ca256e9ea9da7 ]

To meet the 'i' (immediate) constraint for the asm operands,
this function must be always inlined.

[PATCH 5.1 054/121] MIPS: uprobes: remove set but not used variable epc

[Greg Kroah-Hartman]

[ Upstream commit f532beeeff0c0a3586cc15538bc52d249eb19e7c ]

Fixes gcc '-Wunused-but-set-variable' warning:

arch/mips/kernel/uprobes.c: In function 'arch_uprobe_pre_xol':
arch/mips/kernel/uprobes.c:115:17: warning: variable 'epc' set but not used [-Wunused-but-set-variable]

It's never used since introduction in
commit 40e084a506eb ("MIPS: Add uprobes support.")
