kernel/linux.git/arch/mips/include/asm/sim.h, branch v6.19.11Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.19.112018-08-01T20:20:15+00:00MIPS: Remove nabi_no_regargs2018-08-01T20:20:15+00:00Paul Burtonpaul.burton@mips.com2018-08-01T20:12:42+00:00urn:sha1:96a68b14db358c310e1c5cc5229752845192c1fa
Our sigreturn functions make use of a macro named nabi_no_regargs to
declare 8 dummy arguments to a function, forcing the compiler to expect
a pt_regs structure on the stack rather than in argument registers. This
is an ugly hack which unnecessarily causes these sigreturn functions to
need to care about the calling convention of the ABI the kernel is built
for. Although this is abstracted via nabi_no_regargs, it's still ugly &
unnecessary.
Remove nabi_no_regargs & the struct pt_regs argument from sigreturn
functions, and instead use current_pt_regs() to find the struct pt_regs
on the stack, which works cleanly regardless of ABI.

mips: switch to generic sys_fork() and sys_clone()2013-02-03T23:33:02+00:00Al Viroviro@zeniv.linux.org.uk2012-12-27T17:11:46+00:00urn:sha1:50150d2bb9033de8a4d94b3feb2dfed81a605ed5
we still need the wrappers to store callee-saved registers in
pt_regs, but once that done we can jump to kernel/fork.c variants.
