2007-02-26[MIPS] Kill redundant EXTRA_AFLAGSAtsushi Nemoto
Many Makefiles in arch/mips have EXTRA_AFLAGS := $(CFLAGS) line. This is redundant while AFLAGS contains $(cflags-y) and any options only listed in CFLAGS (not in cflags-y) should be unnecessary for asm sources.

2007-02-22[MIPS] Add basic SMARTMIPS ASE supportFranck Bui-Huu
This patch adds trivial support for SMARTMIPS extension. This extension is currently implemented by 4KS[CD] CPUs. Basically it saves/restores ACX register, which is part of the SMARTMIPS ASE, when needed. This patch does *not* add any support for Smartmips MMU features. Futhermore this patch does not add explicit support for 4KS[CD] CPUs since they are respectively mips32 and mips32r2 compliant. So with the current processor configuration, a platform that has such CPUs needs to select both configs: CPU_HAS_SMARTMIPS SYS_HAS_CPU_MIPS32_R[12] This is due to the processor configuration which is mixing up all the architecture variants and the processor types. The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This can lead to a kernel image a little bit bigger than required. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-02-20[MIPS] Fixup copy_from_user_inatomicRalf Baechle
From the 01408c4939479ec46c15aa7ef6e2406be50eeeca log message: The problem is that when we write to a file, the copy from userspace to pagecache is first done with preemption disabled, so if the source address is not immediately available the copy fails *and* *zeros* *the* *destination*. This is a problem because a concurrent read (which admittedly is an odd thing to do) might see zeros rather that was there before the write, or what was there after, or some mixture of the two (any of these being a reasonable thing to see). If the copy did fail, it will immediately be retried with preemption re-enabled so any transient problem with accessing the source won't cause an error. The first copying does not need to zero any uncopied bytes, and doing so causes the problem. It uses copy_from_user_atomic rather than copy_from_user so the simple expedient is to change copy_from_user_atomic to *not* zero out bytes on failure. < --- end cite --- > This patch finally implements at least a not so pretty solution by duplicating the relevant part of __copy_user.

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

2007-02-14[PATCH] sysctl: C99 convert arch/mips/lasat/sysctl.c and remove ABI breakageEric W. Biederman
While C99 converting the ctl_table initializers I realized that the binary sysctl numbers were in conflict with the binary values under CTL_KERN. Including CTL_KERN KERN_VERSION as used by glibc. So I just removed the sysctl binary interface for these values, as it was unsupportable. Luckily these sysctl were inserted at the end of the sysctl list so this bug was not visible to userspace.

The caller of plat_irq_dispatch do setup/restore TI_REGS($28), so dec's plat_irq_dispatch should not do it, and there is no need to adjust RA.
