2010-02-10libc_sh: Add a sysdep header for shCarmelo Amoroso
A new sysdep header for sh (ported from NPTL branch) to provide some useful macros in asm code: ENTRY: an entry point visible from C PSEUDO: a wrapper for syscall with proper errno checking SYSCALL_ERROR_HANDLER: errno check (suitable for TLS) This will help in NPTL integration.

2010-02-10libc: Add a common sysdep headerCarmelo Amoroso
Add a common header file to provide macros useful in asm code: C_LABEL to construct the asm name for a C symbol cfi_xxx to generate eh_frame unwind information. Ported from NPTL branch. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

Thanks, indeed. If we came into "#elif WORDSIZE == 32" block, above condition never be true. So we can just move this statement out of "#if...#elif...#elif...#endif" block. Here is a revised patch. ------------------------------------------------------ From: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Subject: [PATCH] getdents: Fix mips64 build Some archs (such as mips64) do not have getdents64 syscall but have getdents syscall. Define alias for it. This fixes regression from 0.9.30.1. Backgrounds: This is once done by commit e8b1c674. But after the commit 33bcf733 ("Use getdents syscall if kernel provide supports for this instead of relying upon getdents64."), if __ASSUME_GETDENTS32_D_TYPE was defined the alias for getdents64 is not defined. The macro __ASSUME_GETDENTS32_D_TYPE had been effectively ignored until 0.9.30.1 but the commit 0f0f20ab ("Move kernel-features.h header from the linuxthread directory to a common one...") really enables it.

2009-12-19malloc: fix race condition and other bugs in the no-mmu mallocFreeman Wang
Fixes multiple race conditions on mmb list. This was done by making the mmb_heap_lock into a recursive lock and making the regular heap_lock extend to cover the mmb heap handling. Also move the new_mmb allocation up to before the mmb list is iterated through to find the insertion point. When the mmb_heap also runs out and needs to be extended when the regular heap is just extended, the mmb list could be messed up.

2009-12-13syslog: fix openlog(xx, LOG_KERN) and optimize a bitDenys Vlasenko
The fix: logfac == 0 in openlog(xx, logfac) is allowed now. Corresponding internal openlog() call in vsyslog() uses explicit LOG_USER in order to set it as a default facility. Optimizations: mylock is not recursive now, since a single intenal call of openlog is converted to a call to openlog_internal which assumes that lock is already taken. No recursive locking is possible now. LogFacility is reduced to byte. cache static LogFile in auto variable fd (smaller code). vsyslog with bogus pri parameter wouldn't lock/unlock and mess with signals - it will just return at once. pass NULL as ident string in internal openlog call - same effect as passing LogTag but smaller code. comment out "if (LogTag)" checks - it is never NULL. use the same struct sigaction for setting new sigaction and for saving old one - saves ~32 bytes of stack.
